Plastic Smoke Density Tester
The main principle of smoke density measurement is that in a particular space, the cable or material produces smoke under specific combustion or radiation conditions, and the light beam penetrating through the smoke will produce attenuation. Measuring the light transmittance and calculation will get the optical density and smoke density.
The instrument is designed and developed according to ISO5659 related standards. With the use of Conical radiation furnace, the heat flux in the chamber can be as high as 50 kW/ m2, and the sample can be positioned horizontally to test the mass loss rate of the sample. This also complies with the latest IMO test terms. Measure the amount of smoke generated when the sample is vertically exposed to a radioactive heat source at 25 kW / m2 when there is or there is no forward flame in confined space.
Using the standard ISO 5659 conical radiant heating furnace, the user can adjust the heating conditions from 10 kW㎡ into 50 kW/㎡ or 70kW/㎡.
