Abstract

ISO 9772:2012 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/m³, when exposed to an ignition source.

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 e.g. building materials or furnishings under actual fire conditions.

An optional classification system is described in an annex. It 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.
