Fire safety is something that no industry can do away with, especially for buildings and transportation systems.
Contractors or developers have to ensure the chosen materials are up to related Flammability standards at their early stages of construction

Recently, the factory attached to us is doing decoration.
I think one of the things they do very well is that they use flame-retardant aluminum plates to separate the surrounding areas that need to be decorated, so as to avoid fire accidents, we have more time to deal with them.
The Surface flame spread tester is BS6853 series high-speed steel flame retardant tester.
Flame retardant test standard for UK building materials and high-speed steel.
And the length of extension determines the degree of burning. BS 476-7 is primarily used to measure the spread of flames on exposed surfaces of walls and ceilings.
It provides data suitable for comparing the end-use performances of essentially flat materials, composites, or assemblies, which are used primarily as the exposed surfaces of walls or ceilings.
