BS476-6 Fire propagation Tests on Building materials and structures
Meet the standards:
GB / T 17658-1999: Fire Test of Fire Retardant Wood "Fire Test Method"
Scope of application:
Determination of the fire test performance of products used as internal linings in buildings.
BS 476-6: Fire performance of wall and ceiling products is assessed by flame propagation index size.A thermocouple was used to continuously record the difference between the temperature in the chimney and the room temperature, and the results (the curve of temperature difference and time) were compared with the calibration curve, which was measured in the same way with a specified density of asbestos-cement slabs.
BS 476-6 scope of application:
1. Indoor wall materials; 2. Thermal insulation materials; 3. Ceiling materials
Construction systems parts, Fire safety in buildings, Comparative tests, Specimen preparation, Ceilings, Test equipment, Ceiling linings, Structural fire protection, Test specimens, Fire-test classifications, Testing conditions, Walls, Mathematical calculations, Fire tests, Construction materials, Wall linings, Calibration, Fire propagation.
