ASTM 2843 Smoke Density Tester for Building Material
In a fire, people are often smoke suffocated or unable to escape because of the invisible road, so in the prevention of fires, the 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.
