不同试验中有毒气体数据的比较.第1部分:指南和要求

[中文适用范围]： 本文件提供了描述实验室火灾测试中有毒气体产生量的特征的原则，并为比较不同类型和规模的此类测试的结果提供了基础。 它还包括考虑气体测定的不确定性。 综合不确定性是确定测试结果相似性或差异性的关键因素。 实验室规模测试和实际规模测试之间的一致性是否充分取决于火灾危险或风险评估所需的精度，本文件未涵盖这一点。 本文件定义了不同火灾测试中测量的有毒气体数据的相关性和重要性。 通过这样的定义，可以提供关于如何在不同规模和类型的火灾测试之间比较这些数据的通用指导。 火灾测试所代表的燃烧条件、测试和测试样本的其他具体特征、火灾废水的采样策略以及有毒气体种类的分析技术是确定有毒气体重要性时最重要的因素数据。 本文件旨在作为以下工具：a) 定义火灾试验中有毒气体数据的相关性和重要性；b) 不同规模和特性火灾试验中有毒气体数据的比较；以及 c) 有毒气体预测来自基于小规模数据的大规模测试的数据，反之亦然。 本文件提供了有关不同规模物理火灾模型之间有毒气体数据比较的一般指导，但主要针对 ISO 13571 中列出的气体，即二氧化碳 (CO2)、一氧化碳 (CO)、卤化氢（HCl、HBr） 、HF)、二氧化硫ISO 2)、氰化氢(HCN)、氮氧化物(NO、NO2)、甲醛(CH2O)和丙烯醛(C3H4O)。 本文件不适用于火灾试验流出物毒性的表征和比较。 [外文原描述]： This document provides principles for characterizing the measured production of toxic gases from a laboratory fire test and provides bases for comparing the results between different types and scales of such tests. It also includes consideration of the uncertainties in the gas determinations. The combined uncertainty is a key factor in the ability to establish similarity or difference of test results. The sufficiency of the agreement between a bench-scale test and a real-scale test depends on the precision needed in the fire hazard or risk assessment, which is not covered by this document. This document defines the relevance and significance of toxic gas data from measurements in different fire tests. With such a definition it is possible to provide generic guidance on how such data can be compared between different sizes and types of fire tests. The combustion conditions represented by the fire test, other specific characteristics of the test and the test specimen, the sampling strategy of the fire effluents, and the analysis technique for the toxic gas species are the most important factors when defining the significance of the toxic gas data. This document is intended to serve as a tool for the a) definition of the relevance and significance of toxic gas data from fire tests, b) comparison of toxic gas data from fire tests of different scales and characteristics, and c) prediction of toxic gas data from a large-scale test based on small-scale data or vice versa. This document gives general guidance regarding comparison of toxic gas data between physical fire models of different scales, but is principally developed for the gases listed in ISO 13571, i.e. carbon dioxide (CO 2 ), carbon monoxide (CO), hydrogen halides (HCl, HBr, HF), sulfur dioxide (SO 2 ), hydrogen cyanide (HCN), nitrogen oxides (NO, NO 2 ), formaldehyde (CH 2 O) and acrolein (C 3 H 4 O). This document is not applicable to characterization and comparisons of the toxicity of the effluents from fire tests.
