1.1 This International Standard 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. These specimens cannot be tested using method B of IEC 60695-11-10 since they distort or shrink away from the applied flame source without igniting. 1.2 This method of test determines the afterflame and afterglow times of specimens. 1.3 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.
