标准范围

本文件提供了有毒产品产量计算的定义和方程式，以及根据当量比和燃烧效率推导出的燃烧条件。提供了实际案例的示例计算。这些方法旨在为那些有时间分辨数据的实验火灾产生瞬时值或平均值。本文件旨在为消防研究人员提供以下方面的指导:-记录适当的实验火灾数据，-计算火灾试验中火灾流出物中气体和烟雾的平均产量，以及缩尺装置中类似火灾的燃烧，-利用耗氧量和产物生成数据，从当量比和燃烧效率方面描述实验火灾中的燃烧行为。本文件不提供任何特定仪器的操作程序或其中获得的数据解释指南（e。g、 结果的毒理学意义）。

This document provides definitions and equations for the calculation of toxic product yields and the fire conditions under which they have been derived in terms of equivalence ratio and combustion efficiency. Sample calculations for practical cases are provided. The methods are intended to be used to produce either instantaneous or averaged values for those experimental fires in which time-resolved data are available.

This document is intended to provide guidance to fire researchers for

— recording appropriate experimental fire data,

— calculating average yields of gases and smoke in fire effluents in fire tests and fire-like combustion in reduced scale apparatus,

— characterizing burning behaviour in experimental fires in terms of equivalence ratio and combustion efficiency using oxygen consumption and product generation data.

This document does not provide guidance on the operating procedure of any particular piece of apparatus or interpretation of data obtained therein (e.g. toxicological significance of results).
