ASTM D2843 Smoke Density of Building Materials

Introduction: In a fire, people are often smoke suffocated or unable to escape because of the invisible road, so in the prevention of fires, smoke density of the test material is essential. building materials smoke density Tester conforms to the national standard GB/t 8627-2007 specification and requirements, can be used to measure and describe materials, products, components, response to heat and flame under controlled laboratory conditions, measurement of construction materials in combustion or decomposition of the experimental conditions of static yield cigarettes International standards: 1. GBT8627 2. ASTM D2843 Features: 1, The test chamber 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, With the main burner and pilot burner. 7, 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. specification control way computer Power 220VAC 3A 50Hz Weight 50KG Model GD2843
