标准摘要
[中文适用范围]： 本标准规定了细胞塑料水平燃烧特性的测定方法，适用于小火焰作用下的小试样。 [外文原描述]： This document specifies a small-scale laboratory screening procedure for comparing the relative burning characteristics of horizontally oriented, small cellular plastic specimens having a density less than 250 kg⋅m −3 determined in accordance with ISO 845, when exposed to a small-flame ignition source. NOTE Another International Standard which covers flexible cellular plastic and cellular rubber is ISO 3582 [2] . This method of test is intended for quality assurance and limited product evaluation of cellular plastic materials under controlled laboratory conditions, and is not intended to assess the fire behaviour of, for example, building materials or furnishings under actual fire conditions. The optional classification system described in Annex A is intended for the pre-selection of cellular plastic materials for products, including the determination of the ranges of material parameters that give the same classification (see 6.1).
