NBS Plastic Smoke Density Tester
Description
The smoke density box is designed and developed according to lSO5659 related standards. Used in conjunction with a conical radiation furnace
the heat flux in the box can be as high as 50 kw / m2, and the sample can be positioned laterally to test the sample mass loss rate. This is also in line with the latest mo test terms. Measure the density of the smoke cloud when the sampe is measured with or without a forward flame in a
confined space and exposed to a radioactive heat source at 25 kW/m2 vertically. With the lSO 5659 radiant heating furnace. users can
arbitrarily adiust the heatina conditions from 10 kW/m2to 50kW/m2 or70kW/m2
Product Details
The main principle of smoke density measurement is that in a specific space, cables or materials generate smoke under specific burning on
radiating conditions. and the beam will decay after passing throuah the smoke. Measure the liaht transmittance of the beam and calculate the
specific optical density And smoke density
