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).
Abstract
Overview
ISO 9772:2020 - "Cellular plastics - Determination of horizontal burning characteristics of small specimens subjected to a small flame" - is a small‑scale laboratory screening method for comparing the horizontal burning behaviour of cellular plastics with apparent density less than 250 kg·m−3 (per ISO 845). It defines apparatus, specimen preparation, conditioning, test procedure, measurements and reporting for quality assurance and limited product evaluation. The method is intended for controlled laboratory comparisons and pre‑selection of materials, not for predicting full-scale fire behaviour in building or furnishing fires.
Key topics and technical requirements
- Scope and purpose: Horizontal orientation testing of small cellular plastic specimens; optional classification system for pre‑selection (Annex A).
- Material limits: Applies to cellular plastics with density
