BS EN 13501-5:2016 EN 13501-5:2016 (E) 5 Introduction The aim of this European Standard is to define a harmon

26、ized procedure for the classification of roofs/roof coverings exposed to external fire. This classification is based on the test methods listed in Clause 5 and the relevant field of application procedures. This European Standard has been prepared in support of the second essential requirement in the

27、 European Commission (EC) Construction Products Regulation (No 305/2011) and as detailed in the Interpretative document number 2: Safety in case of fire (OJ C62 Vol. 37). The EC has drawn up a list of products which under specified conditions, may be considered to be Class BROOFwithout testing. This

28、 information is given in the Commission Decision of 2000-09-06 establishing the list of products belonging to Classes BROOF(Decision 2000/553/EC 2005/403/EC 2006/600/EC).Additionally there is a procedure by which certain products can be assigned a particular fire classification without the need for

29、testing. Such products have well-established reactions to fire performance and have been agreed by the Standing Committee on Construction. Agreements relating to such products which may be classified without further testing (CWFT) are published in the Official Journal of the EU. NOTE Test reports co

30、nstitute the basis for extended application reports as explained in EN 15725. BS EN 13501-5:2016EN 13501-5:2016 (E) 6 1 Scope This European Standard provides the fire performance classification procedures for roofs/roof coverings exposed to external fire based on the four test methods given in CEN/T

31、S 1187:2012 and the relevant extended application rules. For the classification of a roof/roof covering, only those test methods and those application rules need to be applied for which the corresponding classification is envisaged. Products are considered in relation to their end use application. N

32、OTE The distinction between roofs with a steep slope and facades, in terms of the test and classification standard to be applied, may be subject to national regulations. General information on the four test methods in CEN/TS 1187 is given in Annex A. 2 Normative references The following documents, i

33、n whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

41、ordance with EN 15725 4 Classes of external fire performance of roofs/roof coverings The classification set out in this European Standard is based upon the test methods contained in CEN/TS 1187. That standard incorporates four distinct test methods that correspond to different fire hazard scenarios.

42、 There is no direct correlation between the test methods and hence no generally acceptable hierarchy of classification between them. Products classified in a given class are deemed to satisfy all the requirements of any lower class for the same test method/fire hazard scenario. The classes with thei

43、r corresponding fire performance are given in Table 1. 5 Test methods 5.1 General The four test methods given in CEN/TS 1187 are those to be used for classification purposes for roofs/roof coverings. The selection of the tests to be carried out is specified in 6.3. The classification parameters, the

44、 classes and the corresponding criteria are specified in Clauses 8 and 9. BS EN 13501-5:2016EN 13501-5:2016 (E) 8 5.2 Test 1: Method with burning brands The test evaluates the performance of a roof under the conditions of thermal attack with burning brands. The performance includes the fire spread a

45、cross the external surface of the roof, the fire spread within the roof and the fire penetration. 5.3 Test 2: Method with burning brands and wind The test evaluates the performance of a roof covering under the conditions of thermal attack with burning brands and additional wind. The performance incl

46、udes damaged length both on the roof covering and in the substrate. 5.4 Test 3: Method with burning brands, wind and supplementary radiant heat The test evaluates the performance of a roof under the conditions of thermal attack with burning brands, additional wind and radiant heat. The performance i

47、ncludes the external fire spread and the fire penetration. 5.5 Test 4: Two-stage method incorporating burning brands, wind and supplementary radiant heat The test evaluates the performance of a roof under the conditions of thermal attack with burning brands, wind and radiant heat. The performance in

48、cludes the external fire spread and the penetration by fire. 6 Principles for specimen preparation, testing and classification 6.1 General requirements for specimen preparation In general, this paragraph covers tests 1, 3 and 4. Before testing, the test specimens shall be prepared and conditioned an

49、d, where relevant, mounted in accordance with the relevant test method and product standards or other technical specifications. The external fire performance of a roof/roof covering includes such aspects as external and internal fire spread, external and internal damage, fire penetration and the occurrence of flaming droplets or debris. The external fire performance of a roof/roof covering therefore does not only depend on the burning behaviour of the exposed surface, the roof covering, but also on the influences of several components of the roof,
