Standard Brief
The
Classification for burning behavior rule of building material and
interior material used in specific in China, evaluation of burning
behavior for material, guidance of fire safety design, supervision
of fire safety, the implementation of fire protection design played
an important role, resulting in social and economic
benefits.
