当纺织材料短时间暴露在83 2 kW/m2的对流能量水平下时，该方法对其耐热性和绝缘性进行评级。适用于机织物、针织物、棉絮和非机织物，用作防止偶然、短暂暴露在明火中的衣物。它不用于评估暴露于其他热暴露（如辐射能或熔融金属飞溅）的材料。提供了测试单层或多层试样的程序，无论是与传感器接触还是试样与传感器之间的空气空间。该方法不适用于垂直测试阻燃性时经历完全燃烧的纺织材料。根据这种方法对产品进行测试和评估可能需要使用可能有害的材料和/或设备。 本文件并未涉及与其使用相关的所有安全方面。使用该方法的任何人都有责任在使用前咨询相关部门，并结合任何适用的监管要求制定适当的健康和安全规程。

This method rates textile materials for thermal resistance and insulation when exposed to a convective energy level of 83 2 kW/m2 for a short duration.It is applicable to woven fabrics, knit fabrics, battings, and nonwoven fabrics intended for use as a clothing for protection against a chance, short exposure to open flames. It is not intended for evaluating materials exposed to other thermal exposure such as radiant energy or molten metal splash.Procedures are provided for testing single layer or multiple layer specimens, either in contact with the sensor or with an air space between specimen and sensor.This method is not applicable to textile materials that undergo complete flaming combustion when tested vertically for flame resistance.The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
