Standard Test Method for Density of Smoke from the Burning or Decomposition of Plastics

Importancia y uso:

5.1 Tests made on a material under conditions herein prescribed are of considerable value in comparing the relative smoke obscuration characteristics of plastics.

5.2 This test method serves to determine the extent to which plastic materials are likely to smoke under conditions of active burning and decomposition in the presence of flame.

Note 2: One study5 suggested that visual and instrumental observations from this test compare well with the visual observations of the smoke generated by plastic materials when added to a freely burning large outdoor fire.

5.3 The usefulness of this test procedure is in its ability to measure the amount of smoke obscuration produced in a simple, direct, and meaningful manner under the specified conditions. The degree of obscuration of vision by smoke generated by combustibles is known to be affected by changes in quantity and form of material, humidity, draft, temperature, and oxygen supply.

5.4 Safety Precautions—Products of combustion are toxic. Care shall be taken to guard the operator from the effects of products of combustion.
