Applications:

Floor material thermal radiation board test  meets the requirements of ISO9239-1,2 and GB / T 11785-2005. In the test chamber, the floor covering material is burned in a certain thermal radiation environment to measure the  critical thermal radiation value. It can also be used to measure the critical radiation value of attic floor cellulose insulation material.

Test Results:
1.The critical heat flux (CHF)Kw/m² of  flame spread length transformer can be observed by heat  streamline velocity.
2.If the test time is more than 30 minutes, you can record the fire extinguishing time and the fastest flame spread speed, then converted into critical heat flow.
3.Smoke density measurement part: the smoke density can be measured through the photometric system’s light transmittance .
 
Optical System:
1, The optical system contains a light source of the 2900 ± 100 K color temperature incandescent lamp. Light source is received by the silicon photodiode, equipped with a optical path test shutter, for the use of  0% and 100% calibration.
2, Imported photovoltaic module measures the degree of light attenuation. The system automatically calculates the light transmission and generates light transmission curve, which is free to print.
