If the classification based on the tests and criteria given in Tables 1 and 2 is not appropriate, one or more reference scenarios (representative scale tests typifying agreed hazard scenarios) can be called upon within the context of a defined procedure. This procedure is intended to be the subject of a future European Standard or Commission Decision, on the basis of an agreement between the Commission and the Member States, in consultation with CEN/CENELEC and EOTA. !NOTE 2
Test reports constitute the basis for extended application reports as explained in prEN 15725." SIST EN 13501-1:2007+A1:2009

NOTE It is a product composed of one or more components, substantial and/or non-substantial. 3.1.5 substantial component material that constitutes a significant part of a non-homogeneous product. A layer with a mass/unit area
≥ 1,0 kg/m2 or a thickness ≥ 1,0 mm is considered to be a substantial component 3.1.6 non-substantial component material that does not constitute a significant part of a non-homogeneous product. A layer with a mass/unit area < 1,0 kg/m2 and a thickness < 1,0 mm is considered to be a non-substantial component NOTE Two or more non-substantial layers that are adjacent to each other (i.e. with no substantial component(s) in between the layers) are regarded as one non-substantial component when they collectively comply with the requirements for a layer being a non-substantial component. 3.1.7 internal non-substantial component non-substantial component that is covered on both sides by at least one substantial component 3.1.8 external non-substantial component non-substantial component that is not covered on one side by a substantial component 3.1.9 flooring upper layer(s) of a floor, comprising any surface finish with or without an attached backing and with any accompanying underlay, interlayer and adhesives 3.1.10 linear pipe thermal insulation product length of insulation product designed to fit around pipes, with a maximum outer insulation diameter of
300 mm and not intended for use with cylindrical ducts 3.1.11 substrate product which is used immediately beneath the product about which information is required. NOTE For flooring, it is the floor on which it is mounted or the material which represents this floor. SIST EN 13501-1:2007+A1:2009

Table 1. A classification can only be obtained by undertaking !the tests or the extended application process required" for that particular product. A classification obtained for one product type, e.g. floorings, cannot be interpreted or accepted in a different classification system. 5 !Test methods and field of application rules" 5.1 General The following test methods are specified in relation to the envisaged reaction to fire classification. The relevant classification parameters are given in Tables 1, 2 and 3. !Direct and extended application shall be carried out as described in CEN/TS 15117 and in
prEN 15725." 5.2 Non-combustibility test (EN ISO 1182) This test identifies products that will not, or not significantly, contribute to a fire, regardless of their end use. The test is relevant for the classes A1, A2, A1fl, A2fl, A1L and A2L. 5.3 Heat of combustion test (EN ISO 1716) This test determines the potential maximum total heat release of a product when completely burning, regardless of its end use. The test is relevant for the classes A1, A2, A1fl, A2fl, A1L and A2L. It allows the determination of both the gross heat of combustion (PCS) and the net heat of combustion (PCI). 5.4 Single burning item test (EN 13823) This test evaluates the potential contribution of a product to the development of a fire, under a fire situation simulating a single burning item in a room corner near to that product. The test is relevant for the classes A2, A2L, B, BL, C, CL, D and DL. Under the conditions specified in 8.3.2 the test is also relevant for the class A1. SIST EN 13501-1:2007+A1:2009
