本文件提供了表征实验室火灾试验中测量的有毒气体产量的原则，并为比较不同类型和规模的此类试验的结果提供了基础。它还包括对气体测定中不确定性的考虑。综合不确定度是确定测试结果相似性或差异性的关键因素。实验室规模试验和实际规模试验之间一致性的充分性取决于火灾危险或风险评估所需的精度，这不在本文件的范围内。本文件定义了不同火灾试验中测量的有毒气体数据的相关性和重要性。有了这样的定义，就有可能就如何在不同规模和类型的火灾试验之间比较这些数据提供一般指导。火灾测试所代表的燃烧条件、测试和测试样品的其他具体特征、火灾流出物的采样策略以及有毒气体种类的分析技术是定义有毒气体数据重要性的最重要因素。本文档旨在作为a)火灾试验有毒气体数据的相关性和重要性的定义，b)来自不同规模和特性的火灾测试的有毒气体数据的比较，以及c)基于小规模数据预测来自大规模测试的有毒气体数据，反之亦然。本文件给出了不同规模的物理火灾模型之间有毒气体数据比较的一般指南，但主要是为ISO 13571中列出的气体开发的。e.二氧化碳(CO2)、一氧化碳(CO)、卤化氢(HCl、HBr、HF)、二氧化硫(SO2)、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。
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 thea) 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, andc) 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 (CO2), carbon monoxide (CO), hydrogen halides (HCl, HBr, HF), sulfur dioxide (SO2), hydrogen cyanide (HCN), nitrogen oxides (NO, NO2), formaldehyde (CH2O) and acrolein (C3H4O).This document is not applicable to characterization and comparisons of the toxicity of the effluents from fire tests.
