ISO 9772:2001 Cellular plastics -- Determination of horizontal burning characteristics of small specimens subjected to a small flame

standard by International Organization for Standardization, 04/01/2001

Full Description

This International Standard 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 determined in accordance with ISO 845, 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.

The optional classification system described in annex A is intended for the preselection of cellular plastic materials for products.

The burning behaviour of cellular plastics is influenced by test specimen orientation (vertical or horizontal). This method of test evaluates specimens which are oriented horizontally.
