BSS 7238Measurement of smoke generated by solid materials by determining the attenuation of a light beam.

üBSS 7238 Smoke Density Test – Test Method

The samples need to be dried at 60°C for 24 hours and placed at a temperature of 23°C and a humidity of 50%

The following parameters will be determined:

- Ds 1.5 Optical density after 1.5 minutes

- Ds 4.0 Optical density after 4 minutes
