标准摘要
[中文适用范围]: 本文件规定了总体要求、设备和计算方法,以提供可用于评估整套服装或防护服整体在短时间火焰吞没条件下的性能的结果。该测试方法建立了一个评级系统,以表征由阻燃材料制成的单层和多层服装所提供的热防护。评级基于在实验室模拟火灾中对暴露于对流和辐射能量的全尺寸人体模型的热传递测量,该模拟火灾具有可控的热通量、持续时间和火焰分布。在规定的时间内将热传递数据相加,以得出总传递能量。传递能量和热人体模型防护系数 (TMPF) 评估方法提供了一种量化产品性能的方法。暴露热通量限制在标称水平 84 kW/m2,持续时间为 3 秒至 20 秒,取决于风险评估和对服装的隔热能力的预期。所得结果仅适用于经测试的特定服装或套装,并适用于每项测试的特定条件,特别是热通量、持续时间和火焰分布。本测试方法涵盖了在暴露之前、期间和之后对测试样本的整体行为的目视评估、观察、检查和记录。本测试方法不涉及身体位置和移动的影响。热通量测量还可用于计算预测的暴露导致的皮肤烧伤(见 ISO 13506-2)。本测试方法不模拟高辐射暴露,例如电弧闪光暴露、某些涉及液体或固体燃料的火灾暴露类型,也不模拟核爆炸暴露。注意本测试方法很复杂,要求在测试设置和操作方面都具有很高的技术专业知识。即使与本测试方法中的说明有微小的偏差,也会导致测试结果有很大不同。 [外文原描述]: This document specifies the overall requirements, equipment and calculation methods to provide results that can be used for evaluating the performance of complete garments or protective clothing ensembles exposed to short duration flame engulfment. This test method establishes a rating system to characterize the thermal protection provided by single-layer and multi-layer garments made of flame resistant materials. The rating is based on the measurement of heat transfer to a full-size manikin exposed to convective and radiant energy in a laboratory simulation of a fire with controlled heat flux, duration and flame distribution. The heat transfer data is summed over a prescribed time to give the total transferred energy. Transferred energy and thermal manikin protection factor (TMPF) assessment methods provide a means to quantify product performance. The exposure heat flux is limited to a nominal level of 84 kW/m 2 and durations of 3 s to 20 s dependant on the risk assessment and expectations from the thermal insulating capability of the garment. The results obtained apply only to the particular garments or ensembles, as tested, and for the specified conditions of each test, particularly with respect to the heat flux, duration and flame distribution. This test method covers visual evaluation, observation, inspection and documentation on the overall behaviour of the test specimen(s) before, during and after the exposure. The effects of body position and movement are not addressed in this test method. The heat flux measurements can also be used to calculate the predicted skin burn injury resulting from the exposure (see ISO 13506-2). This test method does not simulate high radiant exposures such as those found in arc flash exposures, some types of fire exposures where liquid or solid fuels are involved, nor exposure to nuclear explosions. NOTE This test method is complex and requires a high degree of technical expertise in both the test setup and operation. Even minor deviations from the instructions in this test method can lead to significantly different test results.
