Reliability testing required by the automotive and accessories industry
Abstract:
汽车及其配件因其复杂性和多样化使用环境，需要进行全面的可靠性测试。这些测试确保零部件在高温、低温、高湿度、低湿度、低压、腐蚀性空气以及快速温度变化等恶劣条件下的性能和耐用性。关键测试包括温湿度循环、快速温度变化、盐雾腐蚀、防水、防尘和热冲击测试，以评估零部件的老化、脆化、腐蚀、机械强度变化等影响，保证汽车及其配件的可靠性和安全性。
Automobiles are complex products composed of thousands of parts, which have to go through various harsh environmental conditions (transportation, storage, work, weather, etc.), so the reliability of auto parts and their finished products is very important. Let's introduce what kind of testing is mainly needed in this industry.
What does the environment have to do with cars and auto parts?
| environment | Product impact |
| high temperature | Aging, gasification, cracking, softening, melting, expansion and evaporation |
| low temperature | Brittleness, icing, shrinkage and solidification, decrease in mechanical strength |
| high relative humidity | corrosion, electrolysis |
| low relative humidity | Dehydration, embrittlement, shrinkage, decrease in mechanical strength |
| low pressure | Mechanical failure, sealing problem |
| corrosive air | Corrosion, electrolysis, surface degradation, increased conductivity, increased contact resistance |
| Rapid temperature changes overheating lead to crack deformation and mechanical failure | Overheating leads to crack deformation and mechanical failure |
| accelerated vibration or shock | Component wear increases structural damage |
Therefore, we need the following environmental test equipment:
Temperature and humidity cycle test, rapid rate temperature test, salt spray corrosion test, waterproof test, dustproof test, thermal shock test, etc.
