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.
