ASTM D 2843 Smoke Density Tester for Building Materials Fire test Equipment

ASTM D 2843 Smoke Density Tester Product Introduction:

The building material smoke density tester is developed according to the ASTM D2843 standard, which means that the flame directly impacts the sample, and after the material burns and produces smoke, the smoke density value (SDR) is determined by blocking the light transmittance. Currently, it is more used in the national standard GB 8624 for smoke density testing of PVC casings, and can also be used for smoke density performance testing of automotive interior materials.

Smoke Density Tester Standards:

ASTM D2843 smoke density test
GB/T 8627 smoke density test
