ASTM D2843 Smoke Density Test Apparatus For Building Material

Application

Suitable used for measuring the somke-producing characteristic of building material under controlled condition of combustion or decomposition, and also can be used for other plastics.

Standards 

ASTM D 2843,DIN 4102

What is smoke density test?

This test measures the amount of smoke given off by a material that is burning or smoldering. The material is tested when it begins to smolder and again when a flame source is added. The smoke density is between 0 (no smoke generated) and 800.
