Plastics - Determination of burning behaviour of thin flexible vertical specimens in contact with a small-flame ignition source

This document specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of vertically oriented thin and relatively flexible plastics specimens exposed to a low-energy-level flame ignition source.NOTE  These specimens cannot be tested using method B of IEC 60695-11-10:2013 since they distort or shrink away from the applied flame source without igniting.This test method determines the afterflame and afterglow times of specimens.The classification system described in Annex A is intended for quality control and the preselection of component materials for products. The classification established by this method of test is applicable only to the material used for the specimens.NOTE  Test results are influenced by material components, e.g. pigments, fillers, concentrations of fire retardants.

Plastics - Determination of burning behaviour of thin flexible vertical specimens in contact with a small-flame ignition source

This document specifies a small-scale laboratory screening procedure for comparing the relative burning behaviour of vertically oriented thin and relatively flexible plastics specimens exposed to a low-energy-level flame ignition source.

NOTE  These specimens cannot be tested using method B of IEC 60695-11-10:2013 since they distort or shrink away from the applied flame source without igniting.

This test method determines the afterflame and afterglow times of specimens.

The classification system described in Annex A is intended for quality control and the preselection of component materials for products. The classification established by this method of test is applicable only to the material used for the specimens.

NOTE  Test results are influenced by material components, e.g. pigments, fillers, concentrations of fire retardants.
