根据CEN/TS 1187:2012中给出的四种测试方法和相关的扩展应用规则，本欧洲标准规定了暴露于外部火灾的屋顶/屋顶覆盖物的防火性能分类程序。 对于屋顶/屋顶覆盖物的分类，仅需要应用那些测试方法和这些应用规则，对其进行相应的分类。 产品被认为是与其最终用途应用相关的。 注意根据试验和分类标准，具有陡坡和外墙的屋顶之间的区别可能需要遵守国家规定。 CEN/TS 1187中四项测试方法的一般信息见附件A.

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/TS 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. NOTE 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.
