First, the building materials and building decoration materials, combustion performance classification
Flammability of building materials refers to all physical and chemical changes that occur during combustion or fire, which are caused by the ignition and flame propagation properties of the material surface, the heat, smoke, charring, weight loss, and toxic product Generation and other characteristics to measure. China's national standard GB8624-97 the combustion properties of building materials will be divided into the following levels.
Class A: Non-combustible Building materials: Materials that do not burn very much.
B1 level: Flammability of building materials: flame retardant materials have a better flame retardant effect. In the case of the fire in the air or under high temperature difficult to fire, not easy to spread quickly, and when the fire away immediately after the combustion to stop.
B2 level: flammable building materials: combustible materials have a certain flame retardant effect. In case of fire in the air or under high temperature will immediately fire burning, easy to lead to the spread of fire, such as wooden pillars, wooden frame, wooden beams, wooden stairs and so on.
B3 level: flammable Building materials: without any fire-retardant effect, easy to burn, the fire is very dangerous.
Second, the correct use of different combustion performance levels of materials
Building materials used in the building materials should comply with the requirements of the national mandatory standards, which is GB50222-95 "building interior design fire protection norms", in the specification requirements of interior decoration design should properly handle the decoration effect and the use of security contradictions, Active use of non-combustible materials and flame retardant materials, try to avoid the use of a large number of smoke or toxic gases in the combustion of the material, so safe and applicable, technologically advanced, economical and reasonable. Therefore, consumers in the choice of building materials or interior decoration materials, in order to ensure the quality of decoration should give priority to non-combustible A-level and flame retardant B1-level products to protect their own safety.
Third, how to choose to meet the requirements of the building materials and interior decoration materials
First, in the choice of first determine their needs, and more observation and comparison, choose a good brand and model.
Then, check the packaging and use of materials to see if there is a clear product of the combustion performance rating, because "the People's Republic of Product Quality Law" Article 27: improper use may endanger personal and property safety products, there should be warning Logo or Chinese warning that fire safety performance of building materials is related to personal property and safety of important performance indicators, should be clearly indicated on the product packaging combustion performance rating, to prevent improper use of the product caused by fire accidents. National Fire Building Materials Quality Supervision and Inspection Center only through the type of products issued by the combustion performance rating identification, but also for individual enterprises to track the quality and tracking the issue of quality tracking, but also with the National Building Materials Testing Center launched a comprehensive cooperation to promote environmental protection logo fire . With the express logo, indicating that manufacturers have made a clear commitment to the product, can be used as a consumer technical judgment, the direct basis for complaints.
Finally, inspection of the selected product quality inspection report, the general should have two reports, namely the physical and chemical properties and combustion performance test report, issued by the different quality inspection agencies, and the best by the national test center issued.
After three carefully selected, consumers can buy the rest assured, safe and quality assurance products.
