本文件规定了一种测定锥形量热计中暴露于辐射热的样品气体排放动力学和产率的方法。气体产量是通过将具有代表性的小样本暴露在有或没有火花点火的外部热流中来确定的。测量流出物（烟雾）中特定气体的浓度。结合计算出的气体质量，可根据试样质量、质量损失或质量损失率确定其产量。本文件使用ISO 19702中所述的傅里叶变换红外（FTIR）光谱，以及适用于该特定应用的试验装置和气体分析仪的附加信息。

This document specifies a method for determining the kinetics and yields of gaseous emissions from a specimen exposed to radiant heat in a cone calorimeter. Gas yields are determined by exposing small representative specimens to an external heat flux with or without spark ignition. The concentrations of specific gases in the effluent (smoke) are measured. In combination with calculated masses of gases, their yields from the specimen mass, mass loss or mass loss rate can be determined. This document uses Fourier-Transform Infrared (FTIR) spectroscopy as described in ISO 19702, with additional information on the test apparatus and gas analyser suitable for this specific application.
