ASTM D2843 Test Density of Smoke From The Burning or Decomposition of Plastics

This Exit Sign Smoke Test Set is used for measuring and observing the relative amounts of smoke produced by the burning or decomposition of plastics. It is intended to be used for measuring the smoke-producing characteristics of plastics under controlled conditions of combustion or decomposition. Correlation with other fire conditions is not implied. The measurements are made in terms of the loss of light transmission through a collected volume of smoke produced under controlled, standardized conditions. Thesmoke density tester is designed so that the flame and smoke is observable.

1, The test chamber of Exit Sign Smoke Test Set is painted, beautiful, durable anti-corrosion;
2, Transparent glass doors for easy observation of the test;
3, Stainless steel sample holder and sample templates;
4, The light absorption rate: 0-100% can be measured continuously. Smoke density resolution 0.1%;
5, The smoke density measurement accuracy: ± 3%;
6, Exit Sign Smoke Test Set is provided with the main burner and pilot burner.
7, The tester is equipped with exhaust fan, exhaust the smoke after test; exhaust volume 1700L/min;
8, 300mm optical path, 480mm height distance above the base;
9, The optical glass is easy to clean and keep clean translucent glass to avoid soot particles adhered to affect light effect.
