1.1 该试验方法用于为安装在固定立式仪器人体模型上的单层服装或防护服提供预测的人类皮肤烧伤损伤，然后将其暴露在实验室中的模拟火灾环境中，该模拟火灾环境具有受控的热通量、火焰分布和持续时间。平均暴露热通量为84 kW/m 2. （2） 卡/秒·厘米 2. )，持续时间最长可达20秒。 1.2 记录单层服装或防护服套装的视觉和物理变化，以帮助理解服装或防护服装套装的整体性能，以及如何解释预测的人类皮肤烧伤结果。 1.3 皮肤烧伤的预测是基于有限数量的实验，其中人类受试者的前臂暴露在高温条件下。 皮肤烧伤的前臂信息被均匀地应用于人体模型的整个身体，除了手和脚。手和脚不包括在皮肤烧伤预测中。 1.4 所获得的测量结果和所记录的观察结果只能适用于使用指定的热通量、火焰分布和持续时间测试的特定服装或套装。 1.5 本标准用于测量和描述材料、产品或组件在受控条件下对热量和火焰的响应，但其本身并未包含在实际火灾条件下对材料、产品和组件进行火灾危险或火灾风险评估所需的所有因素。 1.6 该方法不是火灾试验响应试验方法。 1.7 以国际单位制表示的数值应视为标准。 括号中给出的数值是将其转换为英寸磅单位或热测试常用的其他单位的数学转换。如果合适，为方便起见，将非国际单位四舍五入。 1.8 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.9 火灾测试具有内在的危险性。在进行这些试验时，应对人员和财产采取充分的保护措施。 1.10 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 使用本试验方法测量不同材料、服装、服装套装和系统在暴露于特定火灾时提供的热防护（参见 3.2.2 ， 3.2.3 ， 4.1 和 10.4 )。 5.1.1 该试验方法不模拟高辐射暴露，例如电弧闪光暴露、涉及液体或固体燃料的某些类型的火灾暴露，也不模拟核爆炸暴露。 5.2 该试验方法提供了在指定尺寸的固定直立人体模型上测量服装和服装整体性能的方法。该测试方法用于为暴露在实验室模拟火灾中的特定服装或防护服提供预测的皮肤烧伤损伤。 它不会确定材料性能的合格/不合格。 5.2.1 本试验方法并非质量保证试验。结果不构成材料的性能规范。 5.2.2 本试验方法未涉及身体位置和运动的影响。 5.3 服装提供的热保护的测量是复杂的，并且取决于所使用的设备和技术。在这种范围的测试方法中，建立足以涵盖所有意外事件的细节是不可行的。偏离本测试方法中的说明可能会导致显著不同的测试结果。需要有关传热理论和测试实践的技术知识来评估是否以及与本测试方法中给出的说明的哪些偏离是显著的。 测试方法的标准化减少但并没有消除对此类技术知识的需求。报告任何偏离情况以及结果。

1.1 This test method is used to provide predicted human skin burn injury for single-layer garments or protective clothing ensembles mounted on a stationary upright instrumented manikin which are then exposed in a laboratory to a simulated fire environment having controlled heat flux, flame distribution, and duration. The average exposure heat flux is 84 kW/m 2 (2 cal/s·cm 2 ), with durations up to 20 s. 1.2 The visual and physical changes to the single-layer garment or protective clothing ensemble are recorded to aid in understanding the overall performance of the garment or protective clothing ensemble and how the predicted human skin burn injury results can be interpreted. 1.3 The skin burn injury prediction is based on a limited number of experiments where the forearms of human subjects were exposed to elevated thermal conditions. This forearm information for skin burn injury is applied uniformly to the entire body of the manikin, except the hands and feet. The hands and feet are not included in the skin burn injury prediction. 1.4 The measurements obtained and observations noted can only apply to the particular garment(s) or ensemble(s) tested using the specified heat flux, flame distribution, and duration. 1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. 1.6 This method is not a fire test response test method. 1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units or other units commonly used for thermal testing. If appropriate, round the non-SI units for convenience. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Use this test method to measure the thermal protection provided by different materials, garments, clothing ensembles, and systems when exposed to a specified fire (see 3.2.2 , 3.2.3 , 4.1 , and 10.4 ). 5.1.1 This test method does not simulate high radiant exposures, for example, those found in electric arc flash exposures, some types of fire exposures where liquid or solid fuels are involved, nor exposure to nuclear explosions. 5.2 This test method provides a measurement of garment and clothing ensemble performance on a stationary upright manikin of specified dimensions. This test method is used to provide predicted skin burn injury for a specific garment or protective clothing ensemble when exposed to a laboratory simulation of a fire. It does not establish a pass/fail for material performance. 5.2.1 This test method is not intended to be a quality assurance test. The results do not constitute a material’s performance specification. 5.2.2 The effects of body position and movement are not addressed in this test method. 5.3 The measurement of the thermal protection provided by clothing is complex and dependent on the apparatus and techniques used. It is not practical in a test method of this scope to establish details sufficient to cover all contingencies. Departures from the instructions in this test method have the potential to lead to significantly different test results. Technical knowledge concerning the theory of heat transfer and testing practices is needed to evaluate if, and which departures from the instructions given in this test method are significant. Standardization of the test method reduces, but does not eliminate, the need for such technical knowledge. Report any departures along with the results.
