Some standards for auto parts testing:

Regardless of the luxury version or the beggar version, each part of the car factory configuration has its own standard. In addition to design specifications, each part has its own working environment and job function, which means that each part requires different materials, working environment, corrosion resistance, and dust and water resistance. In order to ensure that each component can be steadily carried out in the team work, these standards have also become necessary conditions.

The performance of materials in different environments: In addition to the characteristics of thermal expansion and contraction of materials, the mechanical properties of materials will also be significantly affected at different temperatures. As a means of transportation, it may face a high temperature of nearly 80 degrees in summer, or it may face ice and snow at minus 20 degrees. Therefore, before assembling the automobile, it is a must to perform various limit tests on the material properties of each component.
Perhaps many car owners were greedy for cheap when repairing cars or replacing certain parts and did not choose the original parts. Since then, some minor problems have occurred in the car. These small problems have a lot to do with the accessories you choose. The accessories that do not meet the original factory standards are not counted if they fail to meet the requirements for use, and may even affect other accessories that work normally and cause malfunctions.

Material aging rate and performance degradation: Acid rain, dust, ozone and other substances in the natural environment will cause certain corrosion to metal and plastic material components. In addition, the aging of auto parts is inevitable. After aging, the mechanical performance will definitely decrease. In order to ensure the normal work of the entire "team", the manufacturer will require each component to be tested according to its own standards.

Mechanical components have their own limits of ability: For those who like to modify, pay special attention. If you improve the performance of a certain mechanical component, it means that the workload of other mechanical components related to it will also increase. Therefore, when refitting, try to choose some that meet the original factory standards or consider enhancing the performance of other related components.

Changing the wheels of low-profile vehicles with high-profile wheels is something that many car owners will do. Some of them feel that since they have changed it, they will simply change to a larger size. This will enhance the performance of the tires, but it is not for the rubber on the suspension. It increases the wear rate. This is just one of the cases. Every component in the car is closely related, so you must do what you can when you modify it.
