If the classification based on the tests and criteria given in Tables 1 and 2 is not appropriate, one or more referencescenarios (representative scale tests typifying agreed hazard scenarios) can be called upon within the context of a definedprocedure. This procedure is intended to be the subject of a future European Standard or Commission Decision, on the basis of anagreement between the Commission and the Member States, in consultation with CEN/CENELEC and EOTA.1 ScopeThis European Standard provides the reaction to fire classification procedure for all construction products, includingproducts incorporated within building elements.Products are considered in relation to their end use application.This document applies to two categories, which are treated separately in this European Standard:-
construction products, excluding floorings;-
floorings.NOTEThe treatment of some families of products is still under review and can necessitate amendments to this standard(see European Decision 2000/147/EC).2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).prEN ISO 1182, Reaction to fire tests for building products - Non-combustibility test (ISO/FDIS 1182:2000).prEN ISO 1716:1998, Reaction to fire tests for building products - Determination of the gross calorific value(ISO/DIS 1716:1998).

- Table 1 for construction products excluding floorings;
- Table 2 for floorings.Products classified in a given class are deemed to satisfy all the requirements of any lower class.5 Test methodsThe following test methods are specified in relation to the envisaged reaction to fire classification. The relevantclassification parameters are given in Tables 1 and 2.5.1 Non-combustibility test (prEN 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 and A2fl.5.2 Calorific potential test (prEN ISO 1716)This test determines the potential maximum total heat release of a product when completely burning, regardless of itsend use.The test is relevant for the classes A1, A2, A1fl and A2fl.It allows the determination of both the gross calorific potential (PCS) and the net calorific potential (PCI).5.3 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 asingle burning item in a room corner near to that product. The test is relevant for the classes A2, B, C and D. Under theconditions specified in 8.3.2 the test is also relevant for the class A1.5.4 Ignitability test (prEN ISO 11925-2)This test evaluates the ignitability of a product under exposure to a small flame. The test is relevant for the classes B,C, D, E, Bfl’, Cfl, Dfl and Efl.

For suchapplications, asymmetrical products may be tested and classified for each side separately.In order to reduce the amount of testing, a series of standard substrates is given in EN 13238 and a set ofrepresentative mounting conditions is given in the relevant test method or product specification. A sponsor, however,may choose none of the standard substrates or the representative mounting conditions, although this will limit the fieldof application of the test results and classifications obtained.In the ignitability test (prEN ISO 11925-2), products are tested with surface flame attack only if in the envisaged enduse application direct flame attack on the edge cannot occur. This is the case for floorings. If edges can be exposedunder end use conditions, both surface and edge flame attacks are applied.7 Number of tests for classification7.1The minimum number of tests is given in the appropriate test method.7.2For a product to claim a particular classification all the relevant criteria, given in Table 1 or 2, shall complywith the stated requirements.7.3For each continuous parameter (T, m, tf, PCS, PCI, FIGRA0,2MJ, FIGRA0,4MJ ,THR600s, SMOGRA, TSP600s,critical heat flux) the selection of the class is based on the mean value (m) of the set of results of this parameter,determined in accordance with the relevant test method, using the following procedure:a) Calculate the mean value (m’) of the set of results for this parameter using the minimum number of tests.b) If m’ lies within the limits for an envisaged class, the value m used for classification is m’.c) If m’ does not lie within the limits for an envisaged class, two additional tests may be carried out.d) If two additional tests are carried out, the results for each parameter in these two tests shall be added to theset of results obtained in the minimum number of tests. Next, the two extremes (highest and lowest) for eachparameter individually shall be excluded. The value m, used for classification, shall then be calculated usingthe remaining set of results for each parameter.7.4For the compliance parameters LFS, Fs and flaming droplets/particles, the selection of the class is based onthe presence of a non-compliance in the set of results of this parameter, determined in accordance with therelevant test method, using the following procedure:a) If the set of results for this parameter does not contain a non-compliance, the result “compliant” shall be usedfor classification.

2,0 MJ/m², shall be tested in accordance with EN 13823 (seeTable 1 – note 2a – FIGRA in this case means FIGRA 0,2MJ).Each substantial component of a non-homogeneous product applying for class A2 shall be tested separately inaccordance with either prEN ISO 1182 or prEN ISO 1716. The non-substantial components of a non-homogeneousproduct shall be tested separately in accordance with prEN ISO 1716 only.8.3.3 Class A2 productsAdditionally, all products applying for class A2 shall be tested in accordance with EN 13823.
