4 General

4.1 Objective

Since the use of metals other than those specified for any given application may

lead to rapid failure, resulting in a hazard to both life and property, it is essential

that the risk of incorrect identification of the metals be reduced to a minimum by

marking in accordance with this specification.

4.2 General Requirement

Metal products ordered to ASTM or equivalent other specification shall, as a

minimum, be marked in accordance with such specification and, in addition, as

further specified below.

4.3 Specification References

Reference is made in this specification to standards mentioned in paragraph 3.2.

5 Marking Terms

5.1 Vendor's Name or Trade Mark

The vendor's name or registered trade mark used shall be that of the

manufacturer who performs the final processing or finishing operation prior to

marketing the product.

5.2 Commercial Designation

5.2.1 The commercial designation shall include a designator of material type,

grade and a designator of physical conditions, temper and/or quality.

5.2.2 The material designations shall include the applicable ASTM, AISI,

DIN, JIS, ISO, BSI or EN specification numbers or numbers of

equivalent specifications.

6 Marking Requirements and Applications

6.1 Marking Methods and Legibility

6.1.1 Markings on metal products shall be legible and sufficient to resist

effacement by contact incidental to normal handling, shipment and

storage. Quick drying, waterproof ink, paint, other suitable marking

substances or electrochemical marking may be used. Stamping is

permitted on carbon steel products except ground bars.

6.1.2 When tags are used they shall be made of a durable non-corroding

material with markings that remain legible after prolonged outdoor

storage. Stamping is the preferred method for marking on metal tags.

6.2 Deleterious Effect

Marking on metal products shall be placed in a manner which will not affect the

usefulness of the product.

6.3 Marking Frequency

The following requirements for frequency of metal identification marking

consider handling, packaging, and the likelihood of identification problems

when metal products are cut in the storehouse or at the construction site.

Minimum marking frequencies are given in the following paragraphs.

6.3.1 Mild carbon steel plate shall be marked at one location on each piece as

shown in Figure 1. High-strength low-alloy steel plate shall be marked

on one place on each piece. Alloy and stainless steel plates, and

nonferrous plates shall be marked in rows of recurring marks at intervals

not greater than 1 m on one face of each plate.

6.3.2 Coated and uncoated mild carbon steel sheet and strip, shall be marked at

one location on the top piece of each lift or shipping unit. Alloy steel

and stainless steel sheet, and strip and non-ferrous sheet metals shall be

marked at each corner of one face of each piece or in rows of recurring

marks at intervals not greater than 1 m on one face of each piece.

6.3.3 Alloy steel, stainless steel and non-ferrous bar, tube stock and keystock

shall be marked at intervals not greater than 1 m throughout the length of

each bar.

6.3.4 Bundled carbon steel bars and shapes shall be marked with two tags

firmly attached to each end of the bundle as shown in Figure 1 of this

specification.

6.3.5 Carbon steel bars and shapes that are not bundled shall be marked at one

end of each bar.

6.3.6 Castings shall be marked in at least one location on each piece; such

markings may be cast in place.

6.3.7 Single and slit coils, and sheets in banded shipping units shall be tagged

as shown in Figure 1 of this specification.
