ISO 17493:2016描述了一种测试方法，用于评估暴露在热空气循环烘箱中的防护服材料或物品和设备的耐热性。该方法旨在评估材料在给定暴露温度下的物理变化。评估材料的定义可见变化，包括收缩测量。 根据防护服材料或测试项目的类型，提供不同的程序。

ISO 17493:2016 describes a test method for evaluating the heat resistance of protective clothing materials or items and equipment when exposed in a hot air circulating oven. The method is intended to evaluate physical changes in a material at a given exposure temperature. Materials are evaluated for defined visible changes including the measurement of shrinkage. Different procedures are provided depending on the type of the protective clothing material or item being tested.
