Plastic Smoke Density Flammability Testing Equipment High Accuracy 2600W
The smoke density (Ds) test method was performed in accordance with ISO 5660-1 ASTM E 662. The samples were tested in a sealed oven with a radiant heat source of 2.5 w/cm2. Beam attenuation tests were performed under open flame and non-flame conditions, respectively. The entire test was conducted for 20 minutes and the maximum smoke density values for the entire 20 minutes were recorded for the 4th minute and the 8th minute.
The main principle is to measure smoke density in a particular space, cable or material produced under specific conditions of combustion or713 radiation. The smoke will course the beam attenuate when passes through the smoke, the light transmittance be use to calculate ratio of the optical density and smoke density.
Smoke density boxes is designed according to ISO5659 standards and also combined the standard of ASTM E662, NES711. IT IS with a conical radiant furnace, heat flux can be up 50 kW / m2, and laterally positioned sample, it also can test the sample mass loss rate.
Applicable to plastic industry, plastics industry, rubber industry, textile industry, painted surface industry, wood industry, etc.
