消防员防护服.生理影响.第1部分:与出汗躯干耦合的热和湿传递的测量

[中文适用范围]： 本文件提供了一种测试方法，用于评估防护织物套装和潜在防护服装套装在规定环境条件下的一系列模拟活动（阶段）中的生理影响。 该标准测试方法描述了用于热生理评估的代表性服装或服装整体的织物组件的基本特性： ——干隔热； ——平均代谢活动和水分管理（干湿传热）期间的冷却特性； ——干燥行为。 默认测量是在代表服装或防护服组合的织物样品上进行的。 除了标准测试方法之外，还可以选择使用相同的测试协议来表征更复杂的防护服套装，包括内衣、空气层和某些设计特征1)。 此外，还可以对成衣进行测量。 该测试方法旨在用于测量和描述服装或服装整体的织物组件响应受控实验室条件下的一系列模拟活动的行为，其结果用于优化服装组合和材料选择。 此外，本文件与 ISO 18640-2 一起旨在用于描述防护服的热生理影响，而不是实际火灾条件下的热应激风险。 该测试的结果可用作热生理负荷风险评估的要素。 [外文原描述]： This document provides a test method for evaluating the physiological impact of protective fabric ensembles and potentially protective clothing ensembles in a series of simulated activities (phases) under defined ambient conditions. This standard test method characterizes the essential properties of fabric assemblies of a representative garment or clothing ensemble for thermo-physiological assessment: — dry thermal insulation; — cooling properties during average metabolic activity and moisture management (dry and wet heat transfer); — drying behaviour. Default measurements are done on fabric samples representing the garment or protective clothing combination. Optionally and in addition to the standard test method, the same testing protocol can be applied to characterise more complex protective clothing ensembles including underwear, air layer and certain design features[1]. In addition, measurements on readymade garments are possible. This test method is intended to be used to measure and describe the behaviour of fabric assemblies of a garment or clothing ensemble in response to a simulated series of activities under controlled laboratory conditions, with the results used to optimize garment combinations and material selection. Furthermore, this document together ISO 18640-2, is intended to be used to describe the thermo-physiological impact of protective clothing but not the risk for heat stress under actual fire conditions. The results of this test can be used as elements of a risk assessment with respect to thermo-physiological load. [1] A study conducted by Empa (Swiss Federal Laboratories for Materials Science and Technology, Switzerland) showed good correlation between results of standard torso tests (without underwear and air layers on fabrics) to tests on fabrics with underwear, tests on fabrics with underwear and air layers and test on readymade garments (with underwear and with or without air layers) of the same material composition. Due to the added thermal insulation values of the additional layers direct comparison of results between different measurement configurations is not possible, however.
