Smoke Density Chamber

The DNG Smoke Density Chamber as per ISO 5659-2 , is considered to be one of the most widely used test equipment for the measurement of the smoke volume generated from the burning material, such as building material, non-metallic material in railway, marine, aeroplane.

The DNG Smoke Density Test is intended primarily for use in research and development and fire safety engineering in buildings, trains, ships, etc., and not as a basis for ratings for building codes or other purposes. No basis is provided for predicting the density of smoke that might be generated by the materials upon exposure to heat and flame under other (actual) exposure conditions. This test procedure excludes the effect of irritants on the eye.
