In the case of purchasing SPC wood floor, the manufacturer often mentions the characteristics of fire safety and flame resistance of SPC wood floor, and its fire safety exceeds B1 level. So what is the meaning of Class B1 fire safety feature? Let's get to know about it with you!
In China's national industry standard gb8624-97, the lighting characteristics of building decoration materials are divided into the following categories:
1. Class A: flame retardant building decoration materials: basically no ignition raw materials.
2. Class B1: flame retardant building decoration materials: flame retardant raw materials have good flame retardant effect. It is difficult to ignite when the gas is used for fire or under the effect of high temperature, so it is not easy to spread rapidly, and the ignition will be terminated immediately when the open fire is removed.
3. Class B2: inflammable building decoration materials: inflammable raw materials have certain flame retardant effect. When the gas is used for fire or under the effect of high temperature, it can catch fire immediately, which is easy to cause the spread of fire accidents, such as columns, wooden roof frames, wooden columns, wooden stairs, etc.
4. Class B3: Flammability building decoration materials: without all the actual effects of flame retardancy, it is very easy to ignite, and the risk factors of fire accidents are quite large.
According to the left and right classification standards, people can see that the fire-retardant level of the floor tile and wood floor is "a", the fire-retardant level of the wood floor is "B2", and the fire-retardant level of the blanket is "B3". The fire safety characteristics of SPC wood floor are not as good as that of brick wood floor, but better than that of wood floor and blanket, which belong to "B1 level".
The raw materials of SPC wood floor are mainly resin and calcium powder. Due to the particularity of raw materials, SPC floor has the characteristics of fire protection,
The fire safety test of kingup SPC wood floor fully conforms to the standard, and has also been verified by the corresponding official test, so there is no need to worry about the quality problems.
This means that SPC wood floor can't be ignited when encountering fire or high temperature. Even if it is driven by a high open fire, it is not easy to produce diffusion, and it is not easy to cause harmful substances of interest. After the open fire is removed, the ignition of SPC wood floor will be terminated immediately.
