This product has a category of use related to environmental conditions:

Type X: Reactive coating system intended for use in all conditions (internal, semi-exposed and exposed) when it is applied with top coat.

Type Z2: Reactive coat intended for internal conditions without high humidity1 content, and excluding

temperatures below 0°C, In this case the reactive coat can be applied without top coat or with any top coat of the system.

3. PREPARATION OF SAMPLES

The test specimens were made according to ETAG 018 part 1 and 2, respect to size and number. The manufacturer performed the application of his product on the steel substrates in presence of the testing laboratory (IETcc, EXOCVA and APPLUS).

Once the product was applied, the product was cured for 28 days (prescribed by the manufacture) at

temperature of 23ºC (2) and 50%(5) relative humidity. The tests were carried out at curing conditions indicated above, except in those indicated cases.

Fire resistance. Fire resistance performance assessment of the coating is reported under:

- Columns, open profiles, APPLUS nº 14-5985-222 - Beams, open profiles, EXOVA nº 338087 - Hollow sections, EXOVA nº 353718

The analysis of the data adopted the numerical regression analysis given in EN 13381-8: using specialised computer software for Columns and Hollow sections, and the graphical method for beams.

The evaluation relates to „H‟ and „I‟ shaped beam, column open sections, and rectangular and circular hollow sections protected with this system, applied in APPLUS and EXOVA, for periods of fire resistance 15 minutes (R15), 30 minutes (R30), 45 minutes (R45), 60 minutes (R60) 90 minutes (R90) and (R120) 120 minutes and for design temperatures in the range 350º to 750ºC.

The loaded steel beams with the maximum and minimum nominal protection thicknesses provide evidence about the adhesive properties of the coating (commonly referred to as „stickability‟) under standard EN fire test conditions. The loaded beams were tested until the central deflection exceeded L/30 (span/30). The loaded beams and the short equivalent reference beams (as beam with open section as tubular section) and a section open tall column with the maximum nominal protection thickness and a short equivalent reference open section column were used to generate factors to be applied to the short section data to correct for stickability.

The details of each specimen, i.e. the section factor (the ratio of the heated perimeter to cross-sectional area – A/V), the protection thickness and duration of heating required for the sections to reach the design steel temperatures are used as data for the analysis. The analysis complied with the following criteria for acceptability defined EN 13381-8: 2010:

(a) For each short section the predicted time to reach each design temperature shall not exceed the time for the corrected temperature to reach the design temperature by more than 15%.

(b) The mean value of all percentage differences in time calculated in the above point “a” shall be less than zero.

(c) A maximum of 30% of individual values of all percentage differences calculated in the above point “a” in time shall be more than zero.

Annex 1 shows the appropriate test and assessment information and the results of the analysis of the data.

4.2 ER.3 Hygiene, health and environment

Statement of dangerous substances. According to the manufacturer's declaration taking account of EOTA TR 034, the product installed does not contain and release any dangerous substance.

NOTE: For environmental use categories type Y and type X the test results could be influenced by the various top coat types and their colours. No generic approach is possible in relation to the type of top coat and the applicant has to test all top coats. However, in order to cover all colours of a particular top coat, a

colour having an index L< 50 on the CIELAB1)

scale (see ISO 7724) shall be selected for test. Components identification

This Annex relates to the use of C-THERM IC600 WB for the fire protection of „H‟ or „I‟ shaped steel beam and column sections and hollow sections. The precise scope is given in the following tables which show the total dry film thickness of C-THERM IC600 WB (excluding primer and top coat) required to provide classifications of R15 to R120 for various design temperatures and section factors. The product is approved on the basis of:

Approval testing in accordance with the principles of EN 13381-8.

A design appraisal against this ETA adopting the numerical regression analysis defined in Annex E of EN 13381-8: 2011 is used for results columns and hollow sections..

A design appraisal against this ETA adopting the graphics methods in Annex E.2 of EN 13381-8: 2013 is used for beams.

The data presented in the tables in this annex refers to beams and columns of open section (three-four side fire exposure) and hollow sections. The data shown is applicable to steel sections blast cleaned to ISO 8501-1 SA21/2 or equivalent and primed with the compatible primers and top coats listed in this ETA. Based on the test data the total dry film thickness of primer and top coat together should not exceed the maximum tested.

The data applies also to other shaped steel open sections that have re-entrant details such as type “U”, “L” and “T”. C-THERM IC 600WB has been exposed to the slowing heating regime defined in Annex A of EN 13381-8 and has satisfied the requirements

The graphs were completed with best fit curves for the nominal thicknesses and were adjusted such that the criteria for acceptability were satisfied for each design temperature (shown as dashed lines on the graphs).

The acceptability criteria for I section beams were as follows:

Acceptibility Criteria % Allowed / Actual 350°C 400°C 450°C 500°C 550°C 600°C 650°C 700°C 750°C

Maximum positive variation (%) 15 12,62 8,33 7,44 7,77 7,82 7,68 7,66 7,39 7,06

Optimistic predictions (%) 30 23,08 23,08 23,08 23,08 23,08 23,08 23,08 23,08 23,08

Overall conservative (%) less than zero -2,41 -2,28 -1,78 -1,72 -2,31 -1,54 -1,50 -1,79 -1,67


Assesment: graphical method The following tables show the thickness required for a determinate temperature with different thickness.
