Page 10 of 46 of ETA 12/0581, issued on 17.01.2013 ANNEX 1 Product performance: Fire resistance 1. This Annex relates to the use of HEMPACORE ONE 43600 and HEMPACORE ONE FD 43601 for the fire protection of: • open sections (‘H’ and ‘I’ shaped) steel beams and columns (see Tables A1.1 to A1.18), • square and circular hollow steel columns (see Tables A1.19 to A1.36). The precise scope is given in the tables which specify the dry film thickness of intumescent coating (without primer and topcoat) required to achieve the classification R for various design temperatures and section factors. 2. The product is approved on the basis of: • Approval testing in accordance with EN 13381-8:2010 and ETAG 018, Part 1 and 2. • Design of the dry film thickness of intumescent coating for the fire protection of open sections following the graphical analysis in accordance with Annex E of EN 13381-8:2010 • Design of the dry film thickness of intumescent coating for the fire protection of square and circular hollow sections following the numerical regression analysis in accordance with Annex E of EN 13381-8:2010. 3. The data presented in this Annex for beams refer to a three-sided fire exposure and for columns to a four-sided fire exposure. 4. The data presented in this Annex are applicable to structural steel (S designation) sections in accordance with EN 10025 11 , excluding S185, blast cleaned to ISO 8501-1 Sa 2 ½ or equivalent, primed with the compatible primers listed in Table 1. The data are applicable to assemblies with or without topcoat. 5. The thicknesses given for open H- and I-sections also apply to steel sections of other shapes, e.g. U, L and T-sections under consideration of the same A/V value. 6. The application of the reactive coating on steel tension members made of structural steel in accordance with EN 10025 is not assessed by this ETA. The application on zinc-coated substrates has not been verified. 11 EN 10025-1 to 6: 2004-2005. Hot rolled products of structural steel implemented.
