标准范围

ISO 6942规定了两种互补方法（方法A和方法B），用于确定热辐射防护服材料的性能。这些测试是在具有代表性的单层或多层纺织品或其他用于防热服装的材料上进行的。它们也适用于与带或不带内衣的隔热服总成的整体结构相对应的总成。方法A用于目视评估热辐射作用后材料的任何变化。使用方法B，确定材料的保护效果。材料可以通过两种方法进行测试，也可以仅通过其中一种方法进行测试。根据这两种方法进行的试验用于对材料进行分类；然而，为了能够说明或预测防护服材料的适用性，有必要考虑其他标准。由于试验是在室温下进行的，因此结果不一定与材料在更高环境温度下的行为一致，因此仅在有限程度上适用于预测由试验材料制成的防护服的性能。

ISO 6942 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 carried out 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, it is necessary to take into account additional criteria.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.
