标准摘要
[中文适用范围]： 本文件规定了两种互补的方法（方法 A 和方法 B），用于确定防护热辐射服装材料在受到热辐射时的行为。这些试验是在代表性单层或多层织物或其他 intendé 用于防护服的材料上进行的。它们也适用于组件，这些组件对应于整体防护服组件的结构，无论是否包含内衣。方法 A 用于对材料在受到热辐射后的任何变化进行视觉评估。通过方法 B 可以确定材料的防护效果。材料可以同时使用这两种方法测试，也可以仅使用其中一种方法进行测试。根据这两种方法的试验结果，可以对材料进行分类；然而，为了能够对材料是否适合用作防护服提出陈述或预测，还需要考虑其他标准。由于试验是在室温下进行的，因此结果不一定与高温环境下的材料行为对应，因此只能在有限程度上用于预测由测试材料制成的防护服性能。 [外文原描述]： This document specifies two complementary methods (method A and method B) for determining the behaviour of materials for heat protective clothing subjected to heat radiation. These tests are carried out on representative single or multi-layer textiles or other materials intended for clothing for protection against heat. They are also applicable to assemblies, which correspond to the overall build up of a heat protective clothing assembly with or without underclothing, Method A serves for visual assessment of any changes in the material after the action of heat radiation. With method B the protective effect of the materials is determined. The materials may be tested either by both methods or only by one of them. The tests according to these two methods serve to classify materials; however, to be able to make a statement or prediction as to the suitability of a material for protective clothing additional criteria must be taken into account. Since the tests are carried out at room temperature the results do not necessarily correspond to the behaviour of the materials at higher ambient temperatures and therefore are only to a limited extent suitable for predicting the performance of the protective clothing made from the materials under test.
