What tests must be done for automotive interior parts?

Automotive interior parts refer to the decorative and functional parts of seats, dashboards, door panels, central consoles, roofs, etc. in cars. These parts not only affect the appearance and comfort of the car, but are also directly related to the safety and durability of the car. Therefore, automotive interior parts must undergo various tests to ensure that their quality and performance meet the relevant standards and requirements. The following are the main tests that must be done for automotive interior parts:

1. Combustion performance test: Automotive interior parts must comply with relevant combustion performance standards to ensure that in the event of a fire, it can reduce the speed of fire spread and reduce the fire hazard. Combustion performance testing usually includes vertical burning test, horizontal burning test and smoke density test, etc.

2. Abrasion resistance test: Automotive interior parts are often subject to wear and friction, so they must undergo an abrasion resistance test to ensure their durability and service life. Wear resistance tests usually include Martindale wear test, TABER wear test, etc.

3. Heat resistance test: Automotive interior parts must withstand the test of high-temperature environments, so they must undergo heat resistance tests to ensure their performance and stability at high temperatures. Heat resistance tests usually include high temperature oven tests, thermal oxygen aging tests, etc.

4. Cold resistance test: Automotive interior parts must withstand the test of low temperature environment, so they must go through cold resistance test to ensure their performance and stability at low temperature. Cold resistance tests usually include low temperature oven test, low temperature impact test, etc.

5. Chemical performance test: Automotive interior parts must meet the relevant chemical performance standards to ensure that they will not cause harm to the human body and will not pollute the environment. Chemical performance testing usually includes volatile organic compound testing, heavy metal content testing, etc.

6. Acoustic performance test: Automotive interior parts have an important impact on the noise and sound inside the car, so they must be tested for acoustic performance to ensure that they can reduce noise and sound transmission. Acoustic performance testing usually includes noise testing, sound isolation testing, etc.

In conclusion, automotive interior parts must undergo various tests to ensure that their quality and performance meet the relevant standards and requirements. These tests can help manufacturers choose the most suitable materials and design solutions to improve the quality and durability of automotive interior parts.
