What tests should be done for car interior parts?

In recent years, the car has gradually become the preferred means of transport for people to get around. With the improvement of environmental protection and safety awareness of automobile products, people pay more and more attention to interior materials when choosing cars. As we all know, a safe and qualified car must meet the detection of harmful substances such as ELVs and VOCs. As everyone knows, automobile interior parts must also meet the following requirements to ensure the environmental protection and safety of the indoor environment.

So what tests should be done? Don\'t leave, they will be revealed immediately.

1. Flame retardant performance

Safe combustion performance is an important indicator of materialsautomotive interior ux. Automotive interior materials, especially textiles, must have good flame retardancy and flame retardancy. In this way, once a fire hazard occurs while in the car, passengers can be assured that they will have enough time to leave, or the fire hazard can be reduced.

Ordinary automobile textile materials can use various fibers. Because their composition and chemical structures are different, their thermal properties and combustion properties are also different. The current standard used for flame retardant performance testing is GB 8410-2006 \"Combustion Characteristics of Automotive Interior Materials\", which applies to all automotive interior materials. Commonly used evaluation methods include: vertical burning test, horizontal burning test, and 45° angle burning test.

2. Atomization performance

Automotive interior materials will undergo various functional arrangements before use. Adhesives are commonly used during the installation process, so the finished car interior materials may contain many low molecular weight volatile compounds. These volatile substances evaporate when heated and condense on car windows and windshields, forming a kind of \"frost\" on their surfaces. Phenomenon. The \"frost\" on the car windows is difficult to remove, so it will seriously affect the driver\'s vision, and the volatile substances suspended in the air can be inhaled into the human body, which will affect health and safety people. Therefore, automotive interior fabrics must have certain anti-fog properties.

Currently, to test the atomization performance of automobi partsThe ISO6452 standard \"Rubber, plastic, artificial leather - Determination of haze characteristics of automobile interior parts\" is adopted internationally, while the QB/T standard \"Physics of leather\" is mainly used in China. and determination of atomization performance during mechanical tests\".

3. Anti-UV performance (photoaging test)

At present, in order To meet the requirements of lighting and light vehicle, the window will occupy a large area. As the sun rises, in some extreme weather conditions, the temperature inside the car can reach 130°C; At sunset , the temperature inside the car drops again, which will greatly affect the relative humidity of the car. Such large hot and cold cycles can accelerate the aging of non-metallic materials, not only affect the life of the material, but equalgreatly affect the aesthetics of the fabric after fading. Therefore, automotive interior materials must have good light and UV resistance. Photoaging tests commonly performed on automobile interior materials include: xenon arc lamp aging test, carbon arc lamp aging test, and ultraviolet light simulated aging test.
