Building material smoke density tester main parameters

　　The building material smoke density tester is suitable for measuring the static smoke production of building materials,their products,and other materials during combustion.It is mainly used for evaluating the flame retardant grade B1 of insulation materials such as extruded polystyrene boards and polystyrene boards,and is also suitable for evaluating the smoke density grade of flame retardant decorative fabrics.

　　Compliant with standards:

　　GB/T 8627-2007"Test Method for Smoke Density of Combustion or Decomposition of Building Materials"
