Plastics — Smoke generation — Part 2: Determination of optical density by a single-chamber test

Specifies a method of measuring smoke production from the exposed surface of specimens of essentially flat materials, composites or assemblies not exceeding 25 mm in thickness when placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet with or without the application of a pilot flame. This method of test is applicable to all plastics and may also be used for the evaluation of other materials (e. g. rubbers, textile-coverings, painted surfaces, wood and other building materials).
