地板防火反应测试 第1部分：使用辐射热源确定燃烧行为（ISO 9239‑1:2025）

[中文适用范围]： 本文件规定了一种方法，用于评估在试验舱中暴露于热流辐射梯度下水平安装的地板在被点火火焰点燃时的抗风燃烧行为和火焰蔓延情况。附录A提供了在需要时评估烟雾发展的详细信息。本方法适用于所有类型的地板，例如纺织地毯、软木、木材、橡胶和塑料覆盖层以及涂层。通过本方法获得的结果反映了地板的防火性能，包括使用任何基材的情况。地板的背面修改、与基材的粘接、垫层或其他改变可能会影响测试结果。本方法不能单独用于描述或评估地板在实际火灾条件下的火灾危险或火灾风险。关于测试方法的精确度信息，请参见附录B。 [外文原描述]： This document specifies a method for assessing the wind-opposed burning behaviour and spread of flame of horizontally mounted floorings exposed to a heat flux radiant gradient in a test chamber, when ignited with pilot flames. Annex A gives details of assessing the smoke development, when required. This method is applicable to all types of flooring, e.g. textile carpet, cork, wood, rubber and plastics coverings as well as coatings. Results obtained by this method reflect the reaction to fire performance of the flooring, including any substrate if used. Modifications of the backing, bonding to a substrate, underlay or other changes of the flooring can affect test results. It cannot be used alone to describe or appraise the fire hazard or fire risk of floorings under actual fire conditions. Information on the precision of the test method is given in Annex B.
