用于防止热和火焰的防护服 - 暴露在火焰和辐射热下的热传递的测定

[中文适用范围]： 本文件规定了一种测试方法，用于测量暴露于对流热和辐射热组合时通过水平安装的阻燃纺织材料传递的热量。 曝光条件调整为纯对流热和纯辐射热的大约 50/50 混合。 总暴露热通量为 84 kW/m2。 当所有结构或子组件均由阻燃材料制成时，该测试方法适用于用作单层或多层结构的任何类型的片材。 它不适用于不阻燃的材料。 该测试方法不适用于评估暴露于任何其他类型热能源的材料，例如仅辐射热或仅火焰接触。 ISO 6942 适用于评估仅暴露于辐射热的材料。 ISO 9151 适用于评估仅因火焰接触而产生的材料。 注：一些（但不是全部）纺织材料在暴露于本测试方法产生的对流热和辐射热后可以点燃并继续燃烧。 [外文原描述]： This document specifies a test method for measuring the heat transferred through horizontally mounted flame-resistant textile materials when exposed to a combination of convective and radiant heat. The exposure conditions are adjusted to be approximately a 50/50 mixture of pure convective heat and pure radiant heat. The total exposure heat flux is 84 kW/m 2 . This test method is applicable to any type of sheet material used either as a single layer or in a multilayer construction when all structures or sub-assemblies are made of flame-resistant materials. It does not apply to materials that are not flame resistant. This test method does not apply to the evaluation of materials exposed to any other type of thermal energy sources, such as radiant heat only or flame contact only. ISO 6942 is applicable when evaluating materials for exposure to radiant heat only. ISO 9151 is applicable when evaluating materials due to flame contact only. NOTE Some, but not all, textiles materials can ignite and continue to burn after exposure to the convective and radiant heat produced by this test method.
