This Part of GB/T 5169 specifies a small-scale laboratory screening method for comparing the relative combustion characteristics of samples of plastics and other non-metallic materials. The ignition source of the comparison test is a small flame with a nominal power of 50W, and the test samples are placed horizontally or vertically. The above test method also measures the linear burning rate and afterflame/afterglow time of the sample in addition to the damage length of the sample. These test methods are applicable to solid materials and foamed plastics whose apparent density is not less than 250kg/m3 when measured according to the method of ISO 845, and are not applicable to materials that shrink when exposed to fire but do not burn; Materials should use the ISO 9773 method. The classification and grading method specified in this part (see 8.4 and 9.4) is applicable to the quality assurance or the parts and component materials used for pre-selection of products. These methods may be used for the preselection of the material only if a positive result is obtained for the thickness of the test piece equal to the minimum thickness practically used.
