标准范围

ISO 12828-2:2016描述了在实验室开发分析方法时用于验证火灾气体分析的工具和技术。它是对ISO 12828-1的补充，ISO 12828-1涉及定量和检测限。所述工具和技术可用于测量量、浓度（摩尔和质量）、体积分数以及浓度或体积分数与时间的关系分析。火灾流出物通常是一种复杂的化学物质基质，强烈依赖于火灾中涉及的材料，但也取决于火灾场景参数（见ISO 19706）。在如此广泛的条件下，可用的分析技术将因基质对方法和可测量浓度范围的影响而不同。可用的分析技术可能在几个方面存在显著差异，例如它们对基质的敏感性以及可以可靠测量的浓度/体积分数范围。由于这些原因，在实际操作中，很难或不可能实现针对每一种感兴趣的火灾排放物的独特参考分析技术。本文件中的工具允许验证消防废水分析的可靠测量范围和条件，从而能够比较各种分析技术。可使用本文件中所含信息的现有国际标准示例包括ISO 19701、ISO 19702、ISO 5660-1中的分析化学方法，以及ISO/TR 16312-2、ISO 16405中讨论的方法中的化学测量，或使用ISO 13571和ISO 13344将其应用于火灾毒性评估。注1:本文件中使用了变量“浓度”，但可以在所有地方用“体积分数”替换，而不改变其含义。这不适用于附件。注2:浓度可通过体积分数乘以相关温度和压力下相关气体的密度来计算。

ISO 12828-2:2016 describes tools and techniques for use in validating the analysis of fire gases when an analytical method is developed in a laboratory. It complements ISO 12828？1, which deals with limits of quantification and detection.The tools and techniques described can be applied to the measurement of quantities, concentrations (molar and mass), volume fractions, and concentration or volume fraction versus time analyses. Fire effluents are often a complex matrix of chemical species, strongly dependent on the materials involved in the fire, but also dependent on fire scenario parameters (see ISO 19706). With such a wide variety of conditions, the analytical techniques available will differ in terms of the influence of the matrix on the methods and on the concentration ranges which can be measured. The analytical techniques available are likely to differ significantly in several respects, such as their sensitivity to the matrix and the range of concentrations/volume fractions which can be reliably measured. For these reasons, a unique reference analytical technique for every fire effluent of interest is, in practical terms, difficult or impossible to achieve. The tools in this document allow verification of the reliable measurement ranges and conditions for the analysis of fire effluents, thereby enabling a comparison among various analytical techniques.Examples of existing International Standards where the information contained in this document can be used are the analytical chemical methods in ISO 19701, ISO 19702, ISO 5660？1, and the chemical measurements in the methods discussed in ISO/TR 16312？2, ISO 16405, or their application to fire toxicity assessment using ISO 13571 and ISO 13344.NOTE 1 The variable "concentration" is used throughout this document, but it can be replaced in all places with "volume fraction" without altering the meaning. This does not apply to the Annexes.NOTE 2 Concentration can be calculated from volume fraction by multiplying by the density of the relevant gas at the relevant temperature and pressure.
