A change in the scope for this standard has been proposed to extend criteria to helmets, hoods, gloves, footwear, and rainwear. A previous petition to the Standards Council indicated that these changes were considered with the scope of the current Technical Committee. Additional input showing specific changes to the standard are being submitted electronically. The industry for flash protection current lacks any specific criteria for these additional items, which are equally important to the protection of workers who may be exposed to accidental flash fires.

Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against ShortDuration Thermal Exposures from Fire


"Flash" fires, or vapor cloud fires, are a very small subset of actual fire types experienced in industrial environments with fire hazards. The potential fires that exist can be in the form of pressurized flammable line breaks (jet fires), flammable liquid spills (pool and running pool fires), combustible dust fires, and fireballs (from Boiling Liquid Vapor Explosions or flammable material container BLEVE). Actual thermal exposures can be in the form of full or partial flame contact or engulfment and/or exposure to the radiant energy from a fire's flame emissive power (e.g., when a worker is not in contact with the flames but is escaping the hazard). The purpose of this standard is to provide minimum specification requirements for PPE to address all of these industrial thermal hazards. This goal is better served with the appropriate generic description "short duration thermal exposures from fire" in the title, which covers all of the noted hazards this standard is designed to address.

The standard should be modified to also address single use garments by the modification of theconditioning criteria applied to these products.


The current edition identified single use garments and the committee has not endeavored to fill this industry gap. Standardization of this arena is needed to provide concurrent performance for products being claimed to offered industrial work protection from flash fires.

Add: D 1683 Standard Test Method for Failure In Sewn Seams of Woven Fabrics


Move Standard D 1683 from Appendix to body of document to make it mandatory. (1)This test method is currently listed in Appendix B, Table B.1, a section of the standard that is not usually read by users because it is not mandatory data. In addition to to the wrong identification in column 1 for the primary measurement (should be"seam strength" not"seam efficiency") the wording used in the description identifies 3 distinct issues: the wording for the application contradicts the phrase "stronger seams" without explaining how or why the fabric that is "stronger" than the seam means that the garment has to be discarded instead of repaired.(2)This test method. D 1683, is the single protocol used with all other NFPA protective clothing standards to determine if the garment manufacturers who are supplied with fabric from ISO 9001/3rd Party certified fabric suppliers and ISO 9001/3rd Party certified recognized component suppliers of buttons, zippers, sewing thread, etc. have assembled all all of the parts together in a way that they can meet the performance requirements in a new garment for major seams and minor seams. The distinction between these two categories of seams will be addressed in Section 3 and in other sections of the standard.

Add: D 6193 Standard Practice for Stitches and Seams

TITLE OF NEW CONTENT

Type your content here ...


This standard, which was formerly the Fed Std 751 for Stitches and Seams, was transitioned to ASTM in 1995, would provide a ready reference for end users to better understand how a garment is being manufactured or repaired.1. In additiion to complete descriptions and drawings of every type of stitch formation (sewing thread configurations), there are line drawings that show the wide range of seam types (fabric configurations) that can be made before two or more planar structures are joined together. It also includes drawings and descriptions of bartacks, buttonholes, and zig-zag stitches, etc.2. Part of the usefulness associated with this standard is the combination of the stitching and seaming vocabulary with the images and drawings. This includes terms such as: overedged seams, lapped seams; lapped-felled seams, chainstitch, safetystitch, lockstitch, and many more.

Delete: Fed Std 191 A, Test Method 1534

See: Section 2.3.2

Add: Commercial Item Descriptions (CID's)

Submitter proposes that the following CID's be added to reference documents:

A-A-55126, Fastener Tape, Hook and Loop, Synthetic, 2006

A-A-55217, Aramid, Spun Thread, (Type I Normal Performance, Type II, High Performance) 2011

A-A-55634, Zippers (Fasteners, Slide Interlocking) 2004


Starting in the 1990's, the US Government transitioned from military specifications (descriptive based documents) to CID's (performance based documents) so that purchases could be made from commercial inventories. These inventories would meet consensus performance requirements that had been agreed to by industry, DLA, and Natick R&D. Each of these identified CID's have multiple performance requirements, that were agreed to by the DoD and industry, that use various tests to evaluate the performance of the following components:(a) Hook and Loop: Uses an Aviation Interiors test for FR treated fastener testing and two ASTM test methods for shear and pull testing(b) Sewing thread: Uses three ASTM test methods to measure (1) melt testing of yarn; (2) break strength, yarn size, and yardage, (3) seam strength of major seams and minor seams(c) Zippers: Uses three ASTM test methods to measure: (1) melt testing of yarn, (2) break strength, yarn size, and yardage, (3) strength of interlocking components

3.3.6 * Cold Weather Insulation Material.

A fabric that consists of one or more nonseparable layers that is used for protection in a low-temperatureenvironment. A cold weather insulation material is not an interlining (see interlining) .



Proposed_TIA_1105_2112_.docx Balloted TIA


Note: This Public Input originates from Tentative Interim Amendment 2112-12-2 (TIA 1105) issued by the Standards Council on August 1, 2013.

The current criteria in NFPA 2112-2012 are not workable to support the inclusion of cold weather insulation materials that provide safe and effective protection of flame resistant garments used for protection of workers against accident flash fires. Changes were made to the 2012 edition of NFPA 2112 without the benefit of a full validation effort. An effort intended to meet this purpose has now been completed by a task group under the direction of the Technical Committee where several prospective cold weather insulation materials were evaluated using existing and proposed test methods that included both current and modified flame resistance and heat/thermal shrinkage resistance testing. Additional evaluations were carried out using full scale manikin testing with garments incorporating the selected cold weather insulation materials in jackets of a simple design to assess effects of simulated flash fires on the clothing and insulation materials.

This effort produced the following two primary findings:

1. One of the cold weather insulation materials included in the investigation exhibited average afterflame times in excess of the 2-second requirement using the current flame resistance test procedures. When tested according to the proposed modified flame resistance test procedures, afterflame times were compliant or near compliant. In addition, the manikin-based testing for the same fabric exhibiting extended afterflame times, showed no unusual burning behavior during manikin testing of full garments where the liner consisted of the cold weather insulation material or showed shrinkage that differed radically from garments using materials that qualify to current NFPA 2112 performance criteria. Based on these findings, the modified flame resistance testing can be utilized for the evaluation of cold weather insulation materials.

It was observed that after flame times were observed to be generally shorter when a 50 mm folded edge was used as compared to a 25 mm folded edge. It was also rationalized that more consistent results would be provided with the 50 mm folded edge for the modified flame test because the specimen is positioned 19 mm into a 38 mm high flame leaving only a 6 mm space between the top of the flame and the beginning of the unprotected (by the folded edge) batting. It was therefore reasoned and consistent with the observed test results that the modified flame resistance test should use a 50 mm folded edge.

Specific changes to NFPA 2112 have been proposed in proposed modifications shown in Section 8.3.

2. Certain cold weather insulation materials exhibited significant distortion in heat/thermal shrinkage resistance testing and thermal shrinkage. Yet, these same materials when employed in the form of a liner in a flame resistant jacket utilizing a lightweight shell material did not show significant differences in their shrinkage (of the liner) with materials that would otherwise pass the NFPA 2112-2013 thermal shrinkage resistance criteria. This further included testing with the jacket samples inverted (turned inside out) representing a “worst case” exposure and wearing configuration where no adverse safety issues were observed. From these results, the exemption of cold weather insulation materials from the thermal shrinkage resistance requirement can be justified. Specific changes to NFPA 2112 implementing these modifications are provided as in paragraphs 7.1.3, 7.1.3.1 (deletion), 7.1.4, and Section 8.4.

It is important to point out that the cold weather insulation material is required to meet a heat resistance


23 of 178 1/23/2015 9:23 AM

requirement and is always covered by an outer (shell) material (paragraph 7.1.4). If it is not, it would not qualify as a cold weather insulation material. It is also important to point out that while these changes were based on testing that did not show any safety of the protective garment to be compromised when presented to a simulated flash fire, conditions may exist for which cold weather insulation materials (and other garment materials) will fail to provide intended levels of protection.

The following substantiations are proposed for the additional changes in this amendment to address cold weather insulation material definitions, labeling, design criteria, performance criteria, and test methods:

• A clarification was added to the definition of cold weather insulation material to indicate that the material is not an interlining. Additional language was also added to distinguish an interlining that is not tested for heat resistance or thermal shrinkage resistance from a cold weather insulation material, which is tested for heat resistance but not thermal shrinkage resistance (paragraphs 3.3.6, 3.3.20, A.3.3.6, and A.3.3.20).

• Additional labeling language was added to require the identification of the cold weather insulation material fiber content, the inclusion of a warning that garments with cold weather insulation materials must be properly secured and that a separate label must be provided on the liner if detachable, that indicates that the liner must not be worn by itself. These changes are covered in paragraph 5.1.2, 5.1.9, 5.1.12, and 5.1.13).

• Design criteria were added to permit garment with sewn-in or detachable liners that utilize cold weather insulation materials but that manufacturers must design removable liners so that the liner cannot be worn without the outer layer (paragraphs 6.4 and A.6.4).

• Changes were made in the performance criteria to clarify to which requirements cold weather insulation materials are tested (paragraphs 7.1.2, 7.1.3, and 7.1.4).

• A clarification was provided to specify that the cold weather insulation material is not tested for thermal protective performance (paragraphs 7.1.1.1 and 7.1.1.2).

• Specific procedures were added to address the modified testing of the cold weather insulation material as specified in U.S. Air Force purchase description NCTRF PD N2-01-3A, Batting, Quilted, Aramid, involving the removal of 50 mm of batting and folding of the face cloth over the remaining batting, as supported by the test information provided above (paragraph 8.3.1.7 and Section 8.3.13). Additional instructions were provided for preparing samples for conditioning by sewing a layer of flame resistant fabric to the cold weather insulation material prior to laundering with its removal following laundering or dry cleaning (paragraphs 8.3.13.1 and 8.3.13.2).

• Modifications for the heat and thermal shrinkage resistance test method were made to clarify that the cold weather insulation materials are not evaluated for thermal shrinkage resistance as supported by the test information above (paragraphs 8.4.1.1 through 8.4.1.5, paragraph 8.4.2.1, and section 8.4.11). Additional instructions were provided for preparing samples for conditioning by sewing a layer of flame resistant fabric to the cold weather insulation material prior to laundering with its removal following laundering or dry cleaning (paragraphs 8.4.3.1 through 8.4.3.3).

For supporting documentation see the doc info pages at www.nfpa.org/2112.

Emergency Nature: The proposed TIA intends to correct a circumstance in which the revised NFPA Standard has resulted in an adverse impact on a product or method that was inadvertently overlooked in the total revision process or was without adequate technical (safety) justification for the action. As currently written, NFPA 2112 includes criteria that create a bias against cold weather insulation materials that is inconsistent with their use and in consistent with demonstrated levels of safety.

The OSHA interpretation of March 2010 encouraging employers to provide their employees with garments certified to a consensus standard like NFPA 2112 has created a need and demand for outerwear garments for cold weather protection that are certified to the NFPA 2112 standard. The current edition of the NFPA 2112 standard does not provide clear methods to properly test and certify garments that incorporate insulation for additional protection from cold weather.

Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire

TIA Log No. 1105

Reference: Various

Comment Closing Date: June 14, 2013

Submitter: Jeffrey O. Stull, International Personnel Protection, Inc.

1. Revise 3.3.6, A.3.3.6, and 3.3.20, and add a new A.3.3.20 to read as follows:

3.3.6* Cold Weather Insulation Material. A fabric that consists of one or more nonseparable layers that is used

for protection in a low-temperature environment. A cold weather insulation material is not an interlining (see

interlining).

A.3.3.6 Cold Weather Insulation Material. Examples of insulation materials are include textile battings(s) alone

or batting(s) that are attached to a face cloth. For example, an insulation material consisting of two layers are

considered nonseparable by the attachment that combines the two layers. The insulation material may or may not

have a face cloth. Cold weather insulation materials generally are provided within the garment such that their area of

coverage coincides with the majority of garment area covering the wearer’s body.

Cold weather insulation material as defined in this standard does not preclude the use of intermediate layers for

additional protection against thermal hazards.

3.3.20* Interlining. Any textile that is incorporated into any garment as a layer between outer and inner layers that

only covers a small portion of the overall garment. [1975, 2009]

A.3.3.20 Interlining. The outer and inner layers are compliant to the fabric requirements of this standard. Examples

of an interlining are a fabric layer used to stiffen the waist band in a pair of pants or a facing fabric used inside the

closure flap of a coverall. Interlining materials do not come in contact with the wearer’s skin or underclothing.

2. Revise subsections 5.1.2, 5.1.9(7), and 5.1.12, and add a new 5.1.13 to read as follows:

5.1.2 At least one product label shall be conspicuously located inside each flame-resistant garment. when the item is

properly assembled with all layers and components in place.

5.1.9(7) Fiber content for each primary fabric layer including cold weather insulation materials, but excluding

interlinings and labels.

5.1.12 Garments with multiple layers, including an outer layer and removable cold weather insulation layer, shall

specify the certified wearable configurations on the label configuration and include a warning on the label stating

that all layers must be properly secured and worn in accordance with the manufacturer’s instructions.

5.1.13 For garments with multiple layers that include an outer layer and a removable cold weather insulation layer, a

label shall be conspicuously attached to the removable insulation layer that states “DO NOT WEAR THIS LINER

BY ITSELF. FOR COMPLIANCE WITH THE FLASH FIRE REQUIREMENTS OF NFPA 2112, THE

COMPLETE GARMENT MUST BE WORN. FOR COMPLIANCE INFORMATION, SEE THE PRODUCT

LABEL ON OUTER GARMENT.”

3. Add new Section 6.4 and subsections 6.4.1, and A.6.4.1 to read as follows:

6.4 Use of a Liner for Cold Weather Insulation. Garments shall be permitted to include liners in their construction

including cold weather insulation materials where the liner is either integral to the garment or removable.

6.4.1* Where garments incorporate a cold weather insulation material as part of a removable lining system, the

garment shall be designed such that the removable liner consisting of the cold weather insulation material cannot be

independently worn.

A.6.4.1 Removable liners are permitted to be worn separately if the liner material(s) independently meets the

appropriate fabric requirements in Chapter 7 including 7.1.1 for heat transfer performance and 7.1.5 for overall flash

fire performance. If the liner contains cold weather insulation materials that are not evaluated to 7.1.1 and 7.1.5 and

do not pass the thermal shrinkage resistance requirement in 7.1.3, then the manufacturer must label the liner as

specified in 5.1.13 and provide a design that does not allow separate wearing of the liner without the outer layer.

This may be demonstrated by the absence of a means of closure for the closure area of shirts, pants, and coveralls.

4. Add new subsections 7.1.1.1 and 7.1.1.2 to read as follows:

7.1.1.1 Where the flame-resistant garment consists of multiple and separable layers intended to be worn separately,

the outer layer and the inner layer or layers shall be separately tested.

7.1.1.2 Where the flame-resistant garment consists of multiple layers intended only to be worn together, only the

outer layer shall be tested.

5. Revise subsections 7.1.2 and 7.1.3 to read as follows:

7.1.2 Fabric, cold weather insulation material, and reflective striping utilized in the construction of flame-resistant

garments shall be tested for flame resistance as specified in Section 8.3, and shall have a char length of not more

than 100 mm (4 in.) and an after-flame of not more than 2 seconds, and shall not melt and drip.

7.1.3 Fabric utilized in the construction of flame-resistant garments, excluding manufacturer’s labels, interlinings,

and cold weather insulation materials, shall be individually tested for thermal shrinkage resistance as specified in

Section 8.4, and shall not shrink more than 10 percent in any direction.

6. Delete existing subsection 7.1.3.1 as follows:

7.1.3.1 Cold weather insulation materials utilized in the construction of flame-resistant garments shall be tested in

accordance with Section 8.4 and shall not shrink more than 20 percent in any direction.

7. Revise subsection 7.1.4 to read as follows:

7.1.4 Fabric, cold weather insulation materials, other textile materials, and reflective striping other than those items

described in 7.1.4.1 and 7.1.4.2, used in the construction of flame-resistant garments shall be individually tested for

heat resistance in their original form as specified in Section 8.4, and shall not melt and drip, separate, or ignite.

8. Add a new subsection 8.3.1.7 to read as follows:

8.3.1.7 Modifications to this test method for testing cold weather insulation materials shall be as specified in 8.3.13.

9. Revise subsections 8.3.3.1, 8.3.3.2, and 8.3.3.3 to read as follows

8.3.3.1 For fabrics and cold weather insulation materials that are designated on the flame-resistant garment label to

be washed, specimens shall be tested before and after 100 cycles of washing and drying as specified in 8.1.3.

13. Delete existing subsection 8.4.8.2 and renumber 8.4.8.3 to 8.4.8.2 to read as follows:

8.4.8.2 Measurements of cold weather insulation material thermal shrinkage shall be made on the side of the fabric

facing the wearer as used in the construction of the garment.

8.4.8.3 8.4.8.2 Testing shall be performed in accordance with 8.4.2 through 8.4.7.

14. Add new subsection 8.4.11 to read as follows:



panel of the cold weather insulation material. A similar-sized cloth piece of 200-g/m2 to 270-g/m2 (6.0-oz/yd2 to

8.0-oz/yd2) flame-resistant fabric meeting all requirements of this standard shall be sewn around the perimeter of the

cold weather insulation material such that the batting side is covered by the fabric .

8.4.11.2 Following wash or dry-clean conditioning, 3 specimens measuring 152 mm × 152 mm (6 in. × 6 in.) shall

be removed from the cold weather insulation material layer of the conditioned panel.

8.4.11.3 Testing shall be performed in accordance with 8.4.2 through 8.4.7, and thermal shrinkage shall not be

measured.

Submitter’s Substantiation: The current criteria in NFPA 2112-2012 are not workable to support the inclusion of

cold weather insulation materials that provide safe and effective protection of flame resistant garments used for

protection of workers against accident flash fires. Changes were made to the 2012 edition of NFPA 2112 without the

benefit of a full validation effort. An effort intended to meet this purpose has now been completed by a task group

under the direction of the Technical Committee where several prospective cold weather insulation materials were

evaluated using existing and proposed test methods that included both current and modified flame resistance and

heat/thermal shrinkage resistance testing. Additional evaluations were carried out using full scale manikin testing

with garments incorporating the selected cold weather insulation materials in jackets of a simple design to assess

effects of simulated flash fires on the clothing and insulation materials.


1. One of the cold weather insulation materials included in the investigation exhibited average afterflame

times in excess of the 2-second requirement using the current flame resistance test procedures. When tested

according to the proposed modified flame resistance test procedures, afterflame times were compliant or

near compliant. In addition, the manikin-based testing for the same fabric exhibiting extended afterflame

times, showed no unusual burning behavior during manikin testing of full garments where the liner

consisted of the cold weather insulation material or showed shrinkage that differed radically from garments

using materials that qualify to current NFPA 2112 performance criteria. Based on these findings, the

modified flame resistance testing can be utilized for the evaluation of cold weather insulation materials.

It was observed that after flame times were observed to be generally shorter when a 50 mm folded edge

was used as compared to a 25 mm folded edge. It was also rationalized that more consistent results would

be provided with the 50 mm folded edge for the modified flame test because the specimen is positioned 19

mm into a 38 mm high flame leaving only a 6 mm space between the top of the flame and the beginning of

the unprotected (by the folded edge) batting. It was therefore reasoned and consistent with the observed test

results that the modified flame resistance test should use a 50 mm folded edge.


2. Certain cold weather insulation materials exhibited significant distortion in heat/thermal shrinkage

resistance testing and thermal shrinkage. Yet, these same materials when employed in the form of a liner in

a flame resistant jacket utilizing a lightweight shell material did not show significant differences in their

shrinkage (of the liner) with materials that would otherwise pass the NFPA 2112-2013 thermal shrinkage

resistance criteria. This further included testing with the jacket samples inverted (turned inside out)

representing a “worst case” exposure and wearing configuration where no adverse safety issues were

observed. From these results, the exemption of cold weather insulation materials from the thermal

shrinkage resistance requirement can be justified. Specific changes to NFPA 2112 implementing these

modifications are provided as in paragraphs 7.1.3, 7.1.3.1 (deletion), 7.1.4, and Section 8.4.

It is important to point out that the cold weather insulation material is required to meet a heat resistance requirement

and is always covered by an outer (shell) material (paragraph 7.1.4). If it is not, it would not qualify as a cold

weather insulation material. It is also important to point out that while these changes were based on testing that did

not show any safety of the protective garment to be compromised when presented to a simulated flash fire,

conditions may exist for which cold weather insulation materials (and other garment materials) will fail to provide

intended levels of protection.

The following substantiations are proposed for the additional changes in this amendment to address cold weather

insulation material definitions, labeling, design criteria, performance criteria, and test methods:

A clarification was added to the definition of cold weather insulation material to indicate that the material is

not an interlining. Additional language was also added to distinguish an interlining that is not tested for

heat resistance or thermal shrinkage resistance from a cold weather insulation material, which is tested for

heat resistance but not thermal shrinkage resistance (paragraphs 3.3.6, 3.3.20, A.3.3.6, and A.3.3.20).

Additional labeling language was added to require the identification of the cold weather insulation material

fiber content, the inclusion of a warning that garments with cold weather insulation materials must be

properly secured and that a separate label must be provided on the liner if detachable, that indicates that the

liner must not be worn by itself. These changes are covered in paragraph 5.1.2, 5.1.9, 5.1.12, and 5.1.13).

Design criteria were added to permit garment with sewn-in or detachable liners that utilize cold weather

insulation materials but that manufacturers must design removable liners so that the liner cannot be worn

without the outer layer (paragraphs 6.4 and A.6.4).

Changes were made in the performance criteria to clarify to which requirements cold weather insulation

materials are tested (paragraphs 7.1.2, 7.1.3, and 7.1.4).

A clarification was provided to specify that the cold weather insulation material is not tested for thermal

protective performance (paragraphs 7.1.1.1 and 7.1.1.2).

Specific procedures were added to address the modified testing of the cold weather insulation material as

specified in U.S. Air Force purchase description NCTRF PD N2-01-3A, Batting, Quilted, Aramid,

involving the removal of 50 mm of batting and folding of the face cloth over the remaining batting, as

supported by the test information provided above (paragraph 8.3.1.7 and Section 8.3.13). Additional

instructions were provided for preparing samples for conditioning by sewing a layer of flame resistant

fabric to the cold weather insulation material prior to laundering with its removal following laundering or

dry cleaning (paragraphs 8.3.13.1 and 8.3.13.2).

Modifications for the heat and thermal shrinkage resistance test method were made to clarify that the cold

weather insulation materials are not evaluated for thermal shrinkage resistance as supported by the test

information above (paragraphs 8.4.1.1 through 8.4.1.5, paragraph 8.4.2.1, and section 8.4.11). Additional



dry cleaning (paragraphs 8.4.3.1 through 8.4.3.3).


Emergency Nature: The proposed TIA intends to correct a circumstance in which the revised NFPA Standard has

resulted in an adverse impact on a product or method that was inadvertently overlooked in the total revision process

or was without adequate technical (safety) justification for the action. As currently written, NFPA 2112 includes

http://www.nfpa.org/2112

criteria that create a bias against cold weather insulation materials that is inconsistent with their use and in consistent

with demonstrated levels of safety.

The OSHA interpretation of March 2010 encouraging employers to provide their employees with garments certified

to a consensus standard like NFPA 2112 has created a need and demand for outerwear garments for cold weather

protection that are certified to the NFPA 2112 standard. The current edition of the NFPA 2112 standard does not

provide clear methods to properly test and certify garments that incorporate insulation for additional protection from

cold weather.


3.3.12 * Flame Resistance.

The property of a material whereby combustion is prevented, terminated, or inhibited following theapplication of a flaming or nonflaming source of ignition, with or without subsequent removal of the ignitionsource.

The definition is not the complete NFPA definition for this term, there is more wording that was omitted. Theomitted wording was

"Flame resistance can be an inherent property of a material or it can be imparted by specific treatment"

The committee has two options to correct this error:

1. Make the change by adding the omitted wording to the current definition for the term "flame resistance",or

2. Add the term "inherent flame resistance" and its definition to Chapter 3:

inherent flame resistance -- flame resistance that is derived from the essential characteristics of the fiber orpolymer from which the textile is made


The current definition for the term "flame resistance is not the complete NFPA definition for this term, there is more wording that was omitted. The omitted wording was "Flame resistance can be an inherent property of a material or it can be imparted by specific treatment "

The committee has two options to correct this error:1. Make the change by adding the omitted owrding to the current defiinition for the term "flame resistance", or add the term "inherent flame resistance" and its definition to Chapter 3:Inherent flame resistance - flame resistance that is derived from the essential characteristics of the fiber or polymer from which the textile is made.

3.3.13 * Flash Fire.

A fire that spreads by means of a flame front rapidly through a diffuse fuel, such as dust, gas, or the vaporsof an ignitible liquid, without the production of damaging pressure. [ 921, 2011]


This standard establishes the minimum performance requirements of PPE for protection of industrial personnel from short duration thermal exposures from industrial fires, not from a specific type of fire. "Flash" fires, or vapor cloud fires are a very small subset of actual fire types experienced in industrial environments with fire hazards. The potential fires that exist can be in the form of pressurized flammable line breaks (jet fires), flammable liquid spills (pool and running pool fires), combustible dust, and fireballs (from Boiling Liquid Expanding Vapor Explosions or flammable material container BLEVE). Actual thermal exposures can be in the form of full or partial flame contact or engulfment and/or exposure to the radiant energy from a fire's flame emissive power (e.g., when a worker is not in contact with the flames but is escaping the hazard). The standard is better served by identifying thermal exposures to fire, which encompasses all of the noted hazards and fits with the established standard's Purpose (1.2.1), rather than singling out a specific fire type (as in the case of "Flash Fires"). As such, a definition specific to "Flash Fires" is not required.

3.3.29 Seam.

Any permanent attachment of two or more protective garment fabrics in a line formed by joining theseparate material pieces.

3.3.29.1 Sewn Seam.

A series of stitches joining two or more separate plies of material(s) of planar structure, such as textiles.[1975, 2009]

Proposal: Submitter proposes that these terms be deleted and replaced with several new terms that providethe end user with valuable, objective, and measurable data that indicates performance.


While these terms and definitions might indicate the joining of two separate pieces of fabric, I believe a different image would come to mind with the following:a. structural integrity - the integration of fabric, components, and seam engineering needed to meet the major seam and minor seam performance requirements of a new FR garment.b. major seam - a critical sewn seam that demonstrates a new garment minimum seam strength of 70 lbf (315N)c. minor seam - a non-critical sewn seam that demonstrates a new garment minimum seam strength of 50 lbf (225N)d. critical seam- a single layer garment junction where failure prevents the wearer from performing assigned tasks because of immediate or imminent danger caused by the failure; requires immediate replacement*on a pair of trousers: this can include the outside seam, the inside seam, the crotch seam, the seat seam, the zipper attachment*on a shirt - this can include the side seam, the shoulder seams, the collar*on a coverall - this can include the outside seam (top - along torso/bottom-along lower trunk), the inside/crotch seat seams, shoulder seams, zippere. non-critical seams - in a single layer garment junction where failure allows the wearer to continue performing the assigned tasks until the earliest opportunity for replacement or repair* on a pair of trousers - this can include a button, a hem, a pocket, a belt loop, a pocket flap* on a shirt - this can include a hem, a pocket, a collar flap, a button* on a coverall - this can include a hem, a pocket, a pocket flap*

Performance after Cleaning

(1) retained seam strength -- the seam strength of either a major seam or a minor seam after a specifiednumber of washings

(2) retained seam strength -- the percentage of structural integrity of a major seam or a minor seam after aspecified number of washings



Following a discussion about NFPA 2112 and NFPA 1977 the submitter and chairman talked about the issue of seam strength after multiple washings. Because there is no "new" garment requirement identified in NFPA 2112, it was agreed to use the NFPA 1977 value for major seams and minor seams. The study will include:1. Using at least 2 seam engneering strategies, make samples of major seams and minor seams for testing four groups of NFPA 2112 fabrics identified by chairman*2. Using D 1683 confirm the structural integrity of major seams and minor seams for the four groups of NFPA identified fabrics*3. Using AATCC 135, 1,V,Ai wash same number of samples of the four groups of fabrics a specified number of times, e.g. 25, 50, 100 times.4. Following the washing of the samples in accordance with AATCC procedure, test specimens for retains seam strength using D 1683.5. Create a report of findings to share with NFPA 2112 committee at fall 2014 meeting (Bring quantity of samples for examination)Fabrics identified: Nomex(R) IIIA; Protera(TM); ComfortBlen(TM); FR Cotton(88/12)

Statement: Additional clothing items were added to the scope of the document.

The current criteria in NFPA 2112-2012 are not workable to support the inclusion of cold weatherinsulation materials that provide safe and effective protection of flame resistant garments used forprotection of workers against accident flash fires. Changes were made to the 2012 edition of NFPA2112 without the benefit of a full validation effort. An effort intended to meet this purpose has nowbeen completed by a task group under the direction of the Technical Committee where severalprospective cold weather insulation materials were evaluated using existing and proposed testmethods that included both current and modified flame resistance and heat/thermal shrinkageresistance testing. Additional evaluations were carried out using full scale manikin testing withgarments incorporating the selected cold weather insulation materials in jackets of a simple design toassess effects of simulated flash fires on the clothing and insulation materials.






It is important to point out that the cold weather insulation material is required to meet a heatresistance requirement and is always covered by an outer (shell) material (paragraph 7.1.4). If it is

not, it would not qualify as a cold weather insulation material. It is also important to point out thatwhile these changes were based on testing that did not show any safety of the protective garment tobe compromised when presented to a simulated flash fire, conditions may exist for which coldweather insulation materials (and other garment materials) will fail to provide intended levels ofprotection.

THIS GARMENT MEETS THE REQUIREMENTS OF NFPA 2112, STANDARD ON FLAME-RESISTANTGARMENTS FOR PROTECTION OF INDUSTRIAL PERSONNEL AGAINST FLASH SHORT

DURATION THERMAL EXPOSURES FROM FIRE, 2012 2017 EDITION. NFPA 2113 REQUIRESUPPER AND LOWER BODY COVERAGE.


"Flash" fires, or vapor cloud fires are a very small subset of actual fire types experienced in industrial environments with fire hazards. The potential fires that exist can be in the form of pressurized flammable line breaks (jet fires), flammable liquid spills (pool and running pool fires), combustible dust, and fireballs (from Boiling Liquid Expanding Vapor Explosions or flammable material container BLEVE). Actual thermal exposures can be in the form of full or partial flame contact or engulfment and/or exposure to the radiant energy from a fire's flame emissive power (e.g., when a worker is not in contact with the flames but is escaping the hazard). The standard is better served by identifying short duration thermal exposures from fire in the label, which encompasses all of the noted hazards and fits with the established standard's Purpose (1.2.1). Also added correction for the next edition (2017).

cal/cm2) and a “contact” HTP rating of not less than 12.6 J/cm2 (3.0 cal/cm2).

Question: It seems that this test sets a similar performance standard to ASTM F1930, 3 seconds at 2cal/second, manikin test. To my understanding, this measures the heatflux to second degree burn, with aminimum performance of 6 cal. The manikin test exposes the fabic (in coverall form) to 6 cal, andmeasures if there is burn or not. Both are evaluating burn at a 6 cal exposure. Both are expensive tests,costing as much as $3000 per fabric. Why don't we specify only one 6 cal burn test? If both tests arenecessary, it would be helpful to include a note explaining the different real world phenomena requiringboth tests to qualify a fabric as providing protection at a 6 cal exposure.


If the HTP performance specification were removed, and the Technical Committee settled on a the manikin 6-cal burn test, tens of thousands of dollars would be saved. Every new 2112-rated fabric would only need to undergo one test to evaluate it's performance with a 6-cal exposure. This would reduce the cost and time of certification substantially, making 2112-certified garments more competitive with their non-certified FR counterparts.

2. Certain cold weather insulation materials exhibited significant distortion in heat/thermal shrinkageresistance testing and thermal shrinkage. Yet, these same materials when employed in the form of aliner in a flame resistant jacket utilizing a lightweight shell material did not show significant differencesin their shrinkage (of the liner) with materials that would otherwise pass the NFPA 2112-2013 thermal


80 of 178 1/23/2015 9:23 AM

shrinkage resistance criteria. This further included testing with the jacket samples inverted (turnedinside out) representing a “worst case” exposure and wearing configuration where no adverse safetyissues were observed. From these results, the exemption of cold weather insulation materials fromthe thermal shrinkage resistance requirement can be justified. Specific changes to NFPA 2112implementing these modifications are provided as in paragraphs 7.1.3, 7.1.3.1 (deletion), 7.1.4, andSection 8.4.

7.1.4.1

Labels and emblems shall not be required to be tested for heat resistance. . Emblems or labels affixed to

the exterior of garments should not be larger than 45 cm 2 (7 inch 2 ) unless the emblem is manufacturedfrom flame resistant materials.


Problem to be resolvedWhile flammable small emblems are unlikely to have significant impact on the performance of an FR garment in terms of body burn, the possibility of burning emblems may still present a safety risk. It is not uncommon for larger emblems to be placed on the back of a garment. Ignition of a larger emblem on the back of a garment where it is not readily visible to the wearer could present a significant risk.

Substantiation Garment manufacturers, rental companies, and end users would benefit from additional guidance as to size of exterior emblems. At least one major manufacturer of FR garments has suggested limiting emblems to the size of a business card. The exact size limitation is not as important as the introduction of language to establish some upper limit in size. Larger emblems could still be employed if manufactured with flame resistant materials. This flame resistance could be demonstrated by ASTM D6413 afterflame time limited to 2 seconds.

The table below represents the survivability for an average individual given the range of burn injury (combined 2nd and 3rd degree burn).1 The rate of survival changes with the age of the individual. For the purpose of this standard, the ages ranges of 5-34, 35-49, and 50-59 are relevant since these age ranges would encompass the ages for the majority of workers. At the current criteria of permitting up to 50% body burn, survivability for each of the respective age ranges is 80%, 60% and 40%. I submit that these levels are unacceptable for workers who should have the expectation for a better than average chance of survival when accidentally exposed to flash fire. The recommendation for a total body burn of not more than 40% would yield survivability rates of 90%, 80%, and 70%, respectively. These rates would provide a greater level of safety for workers without significantly decreasing the range of available clothing material choices.

7.1.5.1

Garments consisting of separable layers, such as a removable cold weather insulation material layer, thatare intended to be worn together or separately shall be tested in all wearable configurations identified bythe manufacturer

Where the flame-resistant garment consists of multiple and separable layers intended to be wornseparately, both of the following shall apply:

(a) Specimen garments consisting of the outer layer only shall be tested.

(b) Specimen garments consisting of the inner layer or layers only shall be tested.

7.1.5.2 Where the flame-resistant garment consists of multiple layers intended only to be worn together,specimen garments consisting of the outer layer only shall be tested .


Note: This Proposal originates from Tentative Interim Amendment 1124-12-1 (TIA 1093) issued by the Standards Council on March 7, 2013.

The current language does not provide requirements for all perceived wearable configurations of garments that consist of multiple layers. This leaves room for interpretation of testing requirements where a garment's finished application was not identified by the standard. The new wording adds this necessary clarification.

Where garments do have removable lining materials, but those lining materials are never intended to be worn without the outer protective layer, the current standard requires redundant testing with little to no benefit of the user. NFPA 2112 has identified TPP, Heat and Thermal Shrinkage and Flame Resistance requirements for fabric materials to identify the minimum testing that would demonstrate a contribution to burn injuries in a flash fire exposure. If the outer layer has been tested and complies with the full scale, manikin test, and the inner layer has been tested and complies with all the fabric tests that have been chosen to identify materials that would contribute to burn injuries, then adding those two layers together should not negatively impact the performance of that composite on the manikin test. By requiring this redundant testing, manufacturers have chosen to not certify these products and therefore they are encouraging users to wear non-certified configurations of these garments.

Emergency Nature: The proposed TIA intends to correct a circumstance in which the revised document has resulted in an adverse impact on a product or method that was inadvertently overlooked in the total revision process. Products consisting of multiple and separable layers are not being submitted for certification because there is confusion regarding the application of this section which mandates redundant evaluation of each layer of material. This leads to the wearing of non-compliant garments by the users and lessens the influence and credibility of NFPA 2112 in the field.

7.2 Thread Requirements.

Specimens of all sewing thread utilized in the construction of flame-resistant garments, excludingembroidery, shall be made of an inherently flame-resistant fiber, shall be tested for heat resistance asspecified in Section 8.6, and shall not melt.

Submitter proposes the following action related to Sections 7.2 and Section 8.6:

Sewing thread used in the construction of flame resistant garments shall be made of inherently flameresistant aramid staple sewing threads that comply to Commercial Item Description (CID) A-A-55217, eitherclassification Type I, Normal Performance or Type II, High Performance.


1. As discussed earlier in section 2.3.3, the CID's were developed as performance based standards that measured sewing thread performance in several other areas other than only melting.The CID uses ASTM Test Method 204 to measure yarn size, break strength, and yardage. A review of the CID shows that both classifications Type I and Type II have a range of several tex sizes, and break strengths, both of which contribute to the strength of major seams and minor seams.2. When a garment has a structural integrity performance requirement that includes a major seam of 70 lbf (325N) and a minor seam of 50 lbf(225N), the performance measurements of the sewing thread needs to include more than just the current requirement for data from the D7138 melting test.3. While the compliance of the current requirements in Sections 7.2 and 8.6 are easily resolved by the purchase of fiber, the other changes proposed in the submitter's public inputs will require revisions to Section 8.6.

8.3.1.7 Modifications to this test method for testing cold weather insulation materials shall be asspecified in 8.3.1.3.












It is important to point out that the cold weather insulation material is required to meet a heat resistance requirement and is always covered by an outer (shell) material (paragraph 7.1.4). If it is not, it would not qualify as


106 of 178 1/23/2015 9:23 AM

a cold weather insulation material. It is also important to point out that while these changes were based on testing that did not show any safety of the protective garment to be compromised when presented to a simulated flash fire, conditions may exist for which cold weather insulation materials (and other garment materials) will fail to provide intended levels of protection.

8.3.13.1 Samples for wash or dry-clean conditioning shall be prepared by cutting a 66-cm × 66-cm

(26-in. × 26-in.) panel of the cold weather insulation material. A similar-sized piece of 200-g/m2 to

270-g/m2 (6.0-oz/yd2 to 8.0-oz/yd2) flame-resistant fabric meeting all requirements of this standardshall be sewn around the perimeter of the cold weather insulation material such that the battingside is covered by the fabric.

8.3.13.2 Following wash or dry-clean conditioning, 5 specimens measuring 75 mm × 300 mm (3 in.× 12 in.) from each of the warp and filling direction shall be removed from the cold weatherinsulation material layer of the conditioned panels.

8.3.13.3 If applicable, all specimens shall be prepared for testing by trimming the scrim material,batting, or other layer(s) away from the face cloth by 50 mm ± 3 mm (2.0 in. ± 1/8 in.) such that theface cloth can be folded back covering the scrim, batting, or other layer(s) by 50 mm ± 3 mm (2.0in. ± 1/8 in.); the folded specimen shall be secured in the specimen holder.










It was observed that after flame times were observed to be generally shorter when a 50 mm folded edge was used as compared to a 25 mm folded edge. It was also rationalized that more consistent results would be provided with the 50 mm folded edge for the modified flame test because the specimen is positioned 19 mm into a 38 mm high flame leaving only a 6 mm space between the top of the flame and the beginning of the unprotected (by the folded edge) batting. It was therefore reasoned and consistent with the observed test results that the modified flame


115 of 178 1/23/2015 9:23 AM

resistance test should use a 50 mm folded edge.

A.1.2.1

Users are cautioned that flammable clothing can contribute to the severity of burn injuries through itsignition and continued burning after exposure to flash fire.

Short-duration thermal exposures can arise from other multiple fire types in industrial environments. Theseinclude, but are not limited to, jet flames, liquid fires (pool fires or running liquid fires), solids fires (fires ofsolid materials or dust fires), warehouse fires, and fires associated with oxygen.


"Flash" fires, or vapor cloud fires are a very small subset of actual fire types experienced in industrial environments with fire hazards. The potential fires that exist can be in the form of pressurized flammable line breaks (jet fires), flammable liquid spills (pool and running pool fires), combustible dust, and fireballs (from Boiling Liquid Expanding Vapor Explosions or flammable material container BLEVE). Actual thermal exposures can be in the form of full or partial flame contact or engulfment and/or exposure to the radiant energy from a fire's flame emissive power (e.g., when a worker is not in contact with the flames but is escaping the hazard). The standard is better served by identifying thermal exposures to fire, which encompasses all of the noted hazards and fits with the established standard's Purpose (1.2.1), rather than a specific fire type (in this case "Flash" fires).

The testing requirements in Chapter 8 of this standard are not intended to establish the limitations of theworking environment for personnel involved in situations that might be exposed to chemical flash fires, butare intended to establish material performance.

Users should be advised that if unusual conditions prevail, or if there are signs of abuse or mutilation of theprotective garment, or if modifications or replacements are made or accessories are added withoutauthorization of the protective garment manufacturer, the margin of protection might be reduced.

Users should be advised that the protective properties in new protective garments, as required by thisstandard, can change as the product is worn and ages.

A.3.3.6 Cold Weather Insulation Material.

Examples of insulation materials are include textile batting(s) alone or batting(s) that are attached to a facecloth. For example, an insulation material consisting of two layers are considered nonseparable by theattachment that combines the two layers. The insulation material may or may not have a face cloth. Coldweather insulation materials generally are provided within the garment such that their area of coveragecoincides with the majority of garment area covering the wearer’s body.

Cold weather insulation material as defined in this standard does not preclude the use of intermediatelayers for additional protection against thermal hazards.











2. Certain cold weather insulation materials exhibited significant distortion in heat/thermal shrinkage resistance testing and thermal shrinkage. Yet, these same materials when employed in the form of a liner in a flame resistant jacket utilizing a lightweight shell material did not show significant differences in their shrinkage (of the liner) with materials that would otherwise pass the NFPA 2112-2013 thermal shrinkage resistance criteria. This further included testing with the jacket samples inverted (turned inside out) representing a “worst case” exposure and


150 of 178 1/23/2015 9:23 AM

wearing configuration where no adverse safety issues were observed. From these results, the exemption of cold weather insulation materials from the thermal shrinkage resistance requirement can be justified. Specific changes to NFPA 2112 implementing these modifications are provided as in paragraphs 7.1.3, 7.1.3.1 (deletion), 7.1.4, and Section 8.4.












The OSHA interpretation of March 2010 encouraging employers to provide their employees with garments certified to a consensus standard like NFPA 2112 has created a need and demand for outerwear garments for cold weather protection that are certified to the NFPA 2112 standard. The current edition of the NFPA 2112 standard does not

A.3.3.x Fire. Fire is the result of combustion, or the chemical process of rapid oxidation (burning)that requires an ignition source, a flammable substance or fuel, and oxygen (usually from air). Inan industrial environment, different types of fires may result from a variety of different events.“Jet” fires typically arise from line breaks or ruptures of pressurized flammable materials. Thesefires can create high velocity, directed “jets”, which may project flames in any direction forconsiderable distances, depending on the characteristics of the source, and burn until the fuel isexhausted or the break is isolated. A pool, or running pool fire, arises from the ignition of spillsand leaks of flammable liquids. The size and intensity is dependent on the amount of materialinvolved and typically extends upward from the surface of the pool. These fires also continue untilthe fuel is exhausted and the source of the leak isolated. A flash, or vapor cloud fire arises fromthe release or presence of a hydrocarbon gas or combustible finely divided particles (e.g., coaldust or grain) that contains a concentration above the lower explosive limit of the chemical. Flashfire characteristics depend on the size of the gas or vapor cloud and local conditions. Whenignited, the flame front may expand outward in the form of a fireball or be driven by externalconvection (wind). The resulting effect of the fireball or flame front’s energy with respect to radiantheat significantly enlarges the hazard areas around the gas released.


A discussion regarding the definition of fire and various industrial fire types is missing from this standard (which defines the minimum PPE requirements for the hazard). This section introduces the general concepts involved and various fire types that may pose hazards to workers.

A.3.3.13 Flash Fire.

A flash fire requires an ignition source and a hydrocarbon atmosphere or atmosphere containingcombustible finely divided particles (e.g., coal dust or grain) that contains a concentration above the lowerexplosive limit of the chemical. Both hydrocarbon and dust flash fires generate temperatures from 540°C to1040°C (1000°F to 1900°F). A flash fire depends on the size of the gas or vapor cloud, and when ignited,the flame front expands outward in the form of a fireball. The resulting effect of the fireball's energy withrespect to radiant heat significantly enlarges the hazard areas around the gas released.


This standard establishes the minimum performance requirements of PPE for protection of industrial personnel from short duration thermal exposures from industrial fires, not from a specific type of fire. "Flash" fires, or vapor cloud fires are a very small subset of actual fire types experienced in industrial environments with fire hazards. The potential fires that exist can be in the form of pressurized flammable line breaks (jet fires), flammable liquid spills (pool and running pool fires), combustible dust, and fireballs (from Boiling Liquid Expanding Vapor Explosions or flammable material container BLEVE). Actual thermal exposures can be in the form of full or partial flame contact or engulfment and/or exposure to the radiant energy from a fire's flame emissive power (e.g., when a worker is not in contact with the flames but is escaping the hazard). The standard is better served by identifying thermal exposures to fire, which encompasses all of the noted hazards and fits with the established standard's Purpose (1.2.1), rather than singling out a specific fire type (as in the case of "Flash Fires"). As such, a definition specific to "Flash Fires" is not required.

MandatoryTests

Heat transferperformance(HTP) (7.1.1)

Methodappears inSection 8.2.

A 150 mm (6 in.) square fabric specimenis placed on a specimen holder thatsuspends the specimen horizontally overtwo Meker burners and a radiant panel.The heat and flame source is adjusted toprovide an exposure heat flux of 84

kW/m2 (2.0 cal/cm2 · sec). A weightedsensor containing a copper calorimeter isplaced on top of the specimen andmeasures the heat transfer through thespecimen. A water-cooled shutterbetween the specimen and heat source iswithdrawn to begin the exposure. The testmeasures the amount of time withcontinuous heating for heat breakthroughresistance (using an arbitrary criterion ofheat through the specimen to cause asecond-degree burn). This time ismultiplied by the exposure heat flux toprovide an HTP rating. HTP ratings aremeasured with the sensor both in“contact” with the specimen and “spaced”6 mm ( 1⁄4 in.) away from the specimen.Note that this test method does not resultin a burn injury prediction. The heatremaining in a test sample is notaccounted for, which would otherwisecontribute to a predicted skin burn injury.

This test is a measure of theunsteady state heat transferproperties of garment materials.The HTP test uses an exposureheat flux that is representative ofa JP4 (Jet Fuel) pool fireenvironment. NFPA 2112requires that specimens have an

HTP rating of 12.6 J/cm2 (3.0

cal/cm2) or more whenmeasured in “contact,”simulating direct contact with the

skin, and 25 J/cm2 (6.0 cal/cm2)or more when measured“spaced,” simulating an air gapbetween the skin and thegarment material. Higher HTPratings indicate better unsteadystate heat transfer performancefor this test but do not correlateto improved predicted skin burninjury performance.

Flameresistance(7.1.2)

ASTM D6413;washing anddrying percommerciallaunderingprocedure ordry cleaning(100 cycles)(Section 8.3)

A 75 mm × 305 mm (3 in. × 12 in.) fabricspecimen is placed in a holder that issuspended vertically over a 38 mm (1 1⁄2in.) high methane-fueled flame. Thespecimen is placed 19 mm ( 3⁄4 in.) intothe flame for 12 seconds. After exposureto the flame, the amount of time duringwhich the specimen continues to burn(after-flame) is recorded. The length ofthe burn or char length is then measuredby attaching a weight to the specimenand measuring the length of the tearalong the burn line. Observations arerecorded if any melting and dripping areobserved. Samples are tested in thismanner both before and after 100wash/dry cycles or 100 dry cleaningcycles.

This test is used to determinehow easily fabrics ignite andhow easily they continue to burnonce ignited. In order to passNFPA 2112, materials cannothave an average after-flametime greater than 2 seconds, achar length greater than 102 mm(4 in.), or any melting withdripping.

Thermalshrinkageresistance(7.1.3)

Methodappears inSection 8.4;washing anddrying percommerciallaunderingprocedure ordry cleaning(3 cycles)

A 381 mm (15 in.) square fabric specimenis marked for width and lengthdimensions and is then suspended in aforced air–circulating oven at 260°C(500°F). Following a 5-minute exposure,the specimen dimensions are remeasuredand then compared against the originalmeasurements to determine the amountof shrinkage. The specimen is examinedfor evidence of melting, dripping,separation, or ignition. Specimens thatdemonstrate such behavior fail the test.

A fabric's resistance toshrinkage of a fabric whenexposed to heat is consideredimportant in minimizing theeffects of a flash short durationthermal exposure from fire.NFPA 2112 permits shrinkage inthis laboratory-based test of 10percent or less. Lower reportedshrinkage indicates fabric that ismore resistant to thermalshrinkage.

Heatresistance(7.1.4/7.3)

Methodappears inSection 8.4;washing anddrying percommerciallaunderingprocedure ordry cleaning(3 cycles)

The exposure used for thermal shrinkageis also used for measuring heatresistance. Fabrics or garmentcomponents not required to meet thermalshrinkage requirements can be 152 mm(6 in.) square specimens. Following a5-minute exposure, the specimen isexamined for evidence of melting anddripping, separation, or ignition.Specimens that demonstrate suchbehavior fail the test. The test is alsoapplied to hardware items.

This test measures how garmentfabrics and components react tothe high heat that could occurduring a flash short durationthermal exposure from fire. Thepurpose of the test is to preventmaterials or components thatwill easily ignite, melt, drip, orseparate during exposure tohigh heat from being used ingarments.

Manikintesting (7.1.5)

ASTM F1930;washing anddrying percommerciallaunderingprocedure ordry cleaning(1 cycle)(Section 8.5)

The fabric is made into a standardizedcoverall design and placed on aninstrumented manikin that is dressed incotton underwear. The manikin issubjected to an overall flame and heat

exposure averaging 84 kW/m2 (2.0

cal/cm2 · sec) for 3 seconds. Sensorsembedded in the manikin's skin predictwhether a second- or third-degree burnwill occur at that specific location. Acomputer program determines thepercentage of the body that would sustainsecond- or third-degree burns.

This test provides an overallevaluation of how the fabricperforms in a standardizedcoverall design. NFPA 2112requires a body burn predictionof 50 percent or less of thesurface area covered by sensors(hands and feet are excluded).Lower percent body burnpredictions indicate greaterprotection provided by the fabric.

Threadmeltingresistance(7.2)

FTMS 191A,1534 (Section8.6)

A small segment of thread used in thestitching of station/work uniforms isplaced in a flask containing an organicsolvent and heated. (The solvent extractssubstances that would interfere with thetest.) Next, the extracted thread segmentis put in a device that slowly heats thethread. The temperature at which thethread begins to melt is the meltingtemperature.

Thread used in flame-resistantgarments must withstandtemperatures of up to 260°C(500°F). If the meltingtemperature is less than 260°C(500°F), the thread fails the test.The temperature, 260°C(500°F), is consistent with theheat resistance test.

Label legibility(7.4)

Methodappears inSection 8.7;washing anddrying percommerciallaunderingprocedure ordry cleaning

Sample labels containing the requiredproduct information are subjected to 100wash/dry or dry cleaning cycles and thenexamined for legibility.

This requirement checks forlabel durability. Following thistest, the labels must remainlegible from a distance of atleast 305 mm (12 in.).

Fabric weight ASTM D 3776

A known, specific area of fabric isweighed using a laboratory balance. Themeasured fabric weight is divided by thearea of the fabric. This yields a fabricweight in ounces per square yard.

Fabric weights are commonlyused to reference materials.

Tensilestrength (grabmethod)

ASTM D 5034

In this test, a 102 mm × 204 mm (4 in. × 8in.) fabric specimen is placed between thetwo grips of a tensile testing machine andpulled in the direction of the specimen'slong axis until it breaks. The forcemeasured at the site of the break isreported as the tensile strength. Tensilestrength is reported for both the warp(machine) and fill (cross-machine)directions of the fabric.

Tensile strength is ameasurement that describes theease with which a wovenmaterial can be pulled apart.Higher tensile strengths indicategreater fabric strength.

Tear strength(Elmendorfmethod)

ASTM D 1424

In this test, a notched 102 mm × 204 mm(4 in. × 8 in.) material specimen is placedinto a test device. The test device uses apendulum that is allowed to fall by its ownweight. The force of the falling pendulumtears the material beyond the notch. Thistest measures the force in pounds that isrequired to continue a tear in the notchedtest specimen. Tear resistance is reportedfor both the warp (machine) and fill(cross-machine) directions of the fabric.

Tear resistance is ameasurement of the ease withwhich a woven fabric can betorn apart. Higher tear strengthsindicate fabrics with greaterresistance to tearing.

Material burststrength

ASTM D 3787

This test measures the force required toburst a knit or stretch woven fabric. Amaterial specimen is clamped over adiaphragm that is inflated until thespecimen bursts. The pressure at whichthe fabric bursts is the burst strength.

Burst strength is a measure ofhow easily a knit fabric can bepenetrated by a hard roundobject. Higher burst strengthindicates fabrics that are moreresistant to bursting.

Launderingshrinkage

AATCC 135;machinecycle 3; washtemp. IV; anddryingprocedure Aiii(number ofcycles to bespecified)

A fabric specimen, on which dimensionsare marked and measured in both itswidth and length, is subjected to aspecified number of separate wash/drycycles under controlled conditions.Following the washing and drying, thedimensions of the material sample arecompared to its original dimensions todetermine the amount of shrinkage.Shrinkage is reported in both the warp(machine) and fill (cross-machine)directions of the fabric.

Laundering shrinkage is ameasure of the percentage afabric shrinks after laundering.Shrinkage measured for a fabricis not necessarily representativeof shrinkage measured for agarment.

Dry cleaning colorfastnessassesses the amount of colorchange, or fading, that occurs inthe fabric following exposure todry cleaning solvents. Fabricswith high color scale ratings aremore resistant to color changesin dry cleaning.

Crockingcolorfastness

AATCC 8

In this test method, a fabric sample isplaced in a device against a white transfercloth. The device rubs the fabric againstthe transfer cloth. The amount of colorthat is transferred to the white transfercloth is assessed by a rating scale ofGrade 1 to 5 in 0.5 increments (similar tolaundering colorfastness).

Crocking colorfastness is ameasure of the amount of coloror dye that is transferred fromthe fabric by rubbing orabrasion. Fabrics with high colorscale ratings are more resistantto loss of color through rubbingfrom wearing.

Lightcolorfastness,continuousxenon-arclamp exposure

AATCC 16,Option e

A fabric specimen is placed in aweatherometer using a water-cooledxenon-arc lamp, which simulates intenseexposure to sunlight and humidity. Theexposure test is conducted for a total oftwo weeks. Following the exposure, thefabric is compared to a color scale chartthat indicates the degree of color change.Color scale ratings range from Grade 1 to5 in 0.5 increments (similar to launderingcolorfastness).

Light colorfastness is a measureof the amount of color loss in afabric due to extended exposureto light. Fabrics with high colorscale ratings are more resistantto fading when exposed tooutdoor light.

Seamefficiency

ASTM D 1683

The strength of a seam is measured inthe same way as fabric tensile strength.In this test, a garment seam specimen isplaced between two grips in a tensiletesting machine and pulled in a directionperpendicular to the seam line until itbreaks. The force to break the seam canbe compared to the force to break thefabric by itself. The location of the breakin the specimen can also be reported.

Seam efficiency compares thestrength of a seam to the fabricthat it joins. Higher seamstrength indicates strongerseams; however, seams thatbreak in the fabric, as opposedto at the stitching or seam area,are stronger than the fabricitself.


"Flash" fires, or vapor cloud fires are a very small subset of actual fire types experienced in industrial environments with fire hazards. The potential fires that exist can be in the form of pressurized flammable line breaks (jet fires), flammable liquid spills (pool and running pool fires), combustible dust, and fireballs (from Boiling Liquid Expanding Vapor Explosions or flammable material container BLEVE). Actual thermal exposures can be in the form of full or partial flame contact or engulfment and/or exposure to the radiant energy from a fire's flame emissive power (e.g., when a worker is not in contact with the flames but is escaping the hazard). The standard is better served by identifying thermal exposures to fire, which encompasses all of the noted hazards and fits with the established standard's Purpose (1.2.1).
