Where oneor more of the components is classified according to a CWFT Decision, the whole kit may beclassified to the lowest class of any component.The potential contribution of a product to a fire does not only depend on its intrinsic propertiesand the thermal attack, but also to a large extent on its end-use situation when incorporated inthe works. Tests shall be conducted therefore to simulate its end-use situation.The reaction to fire classification and relevant testing shall be given for the entire kit, e.g. if thecladding is intended used to be applied with thermal insulation behind, it shall be tested withthis insulation.EN 13823 gives only a general description of the arrangement of the test specimen. UnlessEuropean Standard exists (e.g. EN 438-7), Annex E includes precise, specific informationabout the SBI-Testing for cladding kits.For the time being, performing assessments according to the reaction to fire tests are judgedsufficient in some countries for the determination of the behaviour in fire of the cladding kits; inMember States where regulatory requirements demand full-scale façade testing, such testingshall be performed according to national provisions (no European method currently existing).Such testing does not form part of the ETA assessment.ETAG 03428
