Home decoration using fireproof material standard
When we understand the characteristics of the fire and the main hazards, how should we buy safe and qualified residential decoration and construction materials?

1) Classification of combustion performance of building materials and building decoration materials:
The burning properties of building materials refer to all physical and chemical changes that occur during their combustion or in the event of fire. This property is caused by the ignitability and flame spread of the material surface, heat, smoke, carbonization, weight loss, and toxic products. Measured by other characteristics. China's national standard GB8624-97 divides the combustion performance of building materials into the following categories.
Class A: Non-combustible building materials: Materials that hardly burn.
Class B1: Non-flammable building materials: Flame retardant materials have good flame retardant properties. In the event of an open flame in the air or under high temperature, it is difficult to spread quickly, and the combustion stops immediately after the fire source is removed.
B2 level: flammable building materials: flammable materials have a certain degree of flame retardant effect. In the event of an open flame in the air or under the effect of high temperatures, it will immediately start burning and burning, which can easily lead to the spread of fire, such as wooden pillars, wooden trusses, wooden beams, and wooden stairs.
Class B3: Flammable building materials: No flame-retardant effect, extremely flammable, and high risk of fire.
2) Proper use of materials with different combustion performance levels
The building material products used in buildings should meet the requirements of the national mandatory standards. This is GB50222-95 "Fire Protection Code for Interior Decoration Design of Buildings". The specification requires that the interior decoration design of buildings should properly handle the conflict between the decoration effect and the use safety. , actively use non-flammable materials and flame-retardant materials, try to avoid the use of materials that generate a lot of smoke or toxic gases when burning, so that it is safe to apply, advanced technology, and economical and reasonable.†Therefore, when choosing construction materials or interior decoration materials, consumers should give priority to non-flammable Class A and Class B1 flame-retardant products in order to protect their own safety while ensuring the quality of decoration.
3) How to choose the construction materials and interior decoration materials that meet the requirements
First of all, in the choice of the first to determine their own needs, more observation and comparison, choose a good brand and model;
Then, check the packaging and instructions for use of the material to see if there is an indication of the combustion performance rating of the product, as Article 27 of the “PRC Product Quality Law†states: “Products that may be used in an improper manner and may endanger the safety of people and property shall have "Warning sign or Chinese warning statement", the fire safety performance of building materials is an important performance index involving personal and property safety, and the level of combustion performance should be clearly indicated on the product packaging to prevent fire accidents caused by improper use of the product. The National Fireproof Building Materials Quality Supervision and Inspection Center only issued combustion performance level markings to products that passed type inspections. At the same time, it also tracked the quality of individual companies and issued quality tracking marks. At present, it also cooperated fully with the National Building Materials Testing Center to promote fire protection and environmental protection. Identification. With explicit signs, it shows that the manufacturer has made a clear commitment to the product and can serve as a direct basis for consumers to make technical judgments and complaints.
Finally, to inspect the quality inspection report for selected products, there should normally be two reports, namely physical and chemical performance and combustion performance inspection reports, which are issued by different quality inspection agencies and are preferably issued by a national-level inspection center.
After these three steps are carefully selected, consumers can buy products that are safe, secure, and quality-assured.
