标准编号：ISO 871:2022

中文名称：塑料 采用热风炉测定点火温度

英文名称：Plastics — Determination of ignition temperature using a hot-air furnace

发布日期：2022-02

标准范围

本文件规定了使用热风炉测定塑料闪燃温度和自燃温度的实验室方法。这是用于评估塑料对点火源影响的反应的多种方法之一。注？有关其他点火方法的信息，请参见ISO 10093。该方法不能直接测量材料的燃烧性或燃烧速率，也不能定义所用塑料的安全温度上限，单独使用该方法描述或评估材料、产品或组件在实际火灾条件下的火灾危险或火灾风险是不合适的。然而，该试验的结果适合用作火灾危险或火灾风险评估的要素，该评估考虑了与特定最终用途火灾危险评估相关的所有因素。在这种方法的条件下进行的试验在比较不同材料的相对点火特性方面可能具有相当大的价值。获得的值代表在本试验条件下可能导致材料着火的最低环境空气温度。测试值应根据实际使用条件下的点火敏感性对材料进行排序。本试验方法的结果不适用于消防安全工程计算。

This document specifies a laboratory method for determining the flash-ignition temperature and spontaneous-ignition temperature of plastics using a hot-air furnace. It is one of a number of methods in use for evaluating the reaction of plastics to the effects of ignition sources.NOTE       Information on additional ignition methods can be found in ISO 10093.This method does not give a direct measure of the combustibility or rate of burning of a material or any definition of the safe upper limit of temperature for the plastics in use, and it is inappropriate to use it alone to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test are suitable for use as elements of a fire hazard or fire risk assessment which takes into account all of the factors pertinent to an assessment of the fire hazard of a particular end use.Tests made under conditions of this method are potentially of considerable value in comparing the relative ignition characteristics of different materials. Values obtained represent the lowest ambient air temperature that has the potential to cause ignition of the material under the conditions of this test. Test values are expected to rank materials according to ignition susceptibility under actual use conditions.The results of this test method are not intended for fire safety engineering calculations.
