Which automotive interior materials need to be tested for burning characteristics?

With the rapid development of the automobile industry,Car interior burning, the corresponding internal facilities have gradually increased. Electronic control systems and combustible materials for interior decoration have virtually buried fire hazards for cars. Therefore, it is necessary to pay attention to the safety of the car. The interior decoration materials of the car should be made of high-temperature-resistant and refractory materials as much as possible, Fire protection test,and the fire-resistant agent should be sprayed in the material for flame-retardant treatment. The identification of the horizontal burning characteristics of interior materials in automobiles (sedan, multi-purpose passenger car, truck and passenger car) requires an automotive interior material burning test apparatus.

What are the automotive interior decoration materials? Automotive interior materials refer to various interior organic materials used in automobiles such as seat belts, seat cushions, and instrument panels. They include fillers and cushioning devices used to absorb collision energy in the event of a collision. Automotive interior materials are very diverse. If we divide the materials according to their raw materials, they can be divided into the following three categories:

The first is fiber. For example: seat fabrics, carpets and airbags inside the car;

The second is plastic foam. For example: ceiling, door panels, etc. in the car;

The third is rubber. If this type of material is further divided, it can be divided into two categories: synthetic rubber and natural rubber, such as car tires.

Most of the interior materials of automobiles are made of polymer materials. These materials themselves are composed of carbon, hydrogen and other elements, which are organic substances, and most of them are flammable and combustible items. In this way, it will have a high calorific value and release rate during the combustion process, and the flame after burning also has a very fast propagation speed, making it difficult to extinguish it. In addition, in the process of burning, it often generates toxic gas and thick smoke, which will cause great harm to the health of personnel and the natural environment. Therefore, automotive interior materials are tested for combustion safety performance testing, melting performance testing, smoke density and smoke toxicity testing. The burning test standard for automobile interior materials is one of the important factors to ensure the safety of automobiles.
