1, China's national standard GB8624-97 combustion properties of the materials divided into the following levels:
Class A: non-flammable materials: inorganic material hardly combustion occurs.
B1 level: flame-retardant materials: flame-like material has a good fire-retardant effect. In case of fire it in the air or at high temperature difficult fire quickly spread easily occur.
B2 level: Combustible materials: combustible materials have a certain type flame retardant. In case of fire in the air or at high temperature will immediately burst into flames, easily lead to the spread of fire, such as poles, wooden frame, wooden beams, wooden stairs.
B3 level: Flammable materials: no flame effect, highly flammable, fire risk is high.
