Cellular plastics — Determination of horizontal burning characteristics of small specimens subjected to a small flame
Preview
Summary
1.1 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]
.
1.2 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.
1.3 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).
