Product Description

Product Description

The main principle of smoke density measurement is that in a specific space, cables or materials generate smoke under specific combustion or radiation conditions. The light beam will attenuate after passing through the smoke. The transmittance of the light beam is measured and the relative optical density and smoke density are calculated.
Our smoke density chamber is designed and developed according to ISO5659. When used with a conical radiation furnace, the heat flux in the chamber can reach up to 50 kW/m2, and the sample can be positioned horizontally to test the sample mass loss rate. This also complies with the latest IMO test provisions. The smoke density generated by the sample is measured when it is vertically exposed to a radioactive heat source of 25 kW/m2 with or without a front flame in a confined space.

Standard

• GB/T8323.2-2008
