标准范围

本文件规定了两种互补方法（方法A和方法B），用于测定热辐射下隔热服材料的性能。这些测试是在具有代表性的单层或多层纺织品或其他防热服装材料上进行的。它们也适用于组件，这些组件对应于带或不带内衣的隔热服组件的整体构造，方法A用于目视评估热辐射作用后材料的任何变化。用方法B测定材料的保护效果。可通过两种方法或仅通过其中一种方法对材料进行测试。根据这两种方法进行的试验用于对材料进行分类；然而，为了能够就防护服材料的适用性作出声明或预测，必须考虑附加标准。由于试验是在室温下进行的，因此结果不一定与材料在更高环境温度下的行为相符，因此仅在有限的范围内适用于预测由受试材料制成的防护服的性能。

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.
