Standard Test Method for Measuring the Comparative Burning Characteristics and Resistance to Burn-Through of Solid Plastics Using a 125-mm Flame

Importancia y uso:

5.1 The test results present afterflame plus afterglow times, in seconds, for a material under the conditions of the test. The test results for plaques also indicate whether or not the specified flame will burn through a material.

5.2 The test is capable of assessing the effects of material thickness, colors, additives, deterioration, and possible loss of volatile components on afterflame and afterglow.

5.3 The burning characteristics is found to vary with thickness. Test data shall be compared only with data for material of the same thickness.

5.4 The results serve as a reference for comparing the relative performance of materials and can be an aid in material selection.

5.5 In this test method, the specimens are subjected to one or more specific laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it will not always be possible by or from this test method to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire-test-exposure conditions described in this test method.
