Temperature and humidity cycle test
 
Test purpose
 
High and low temperature cycle test purpose: to test the effect of thermal stress on product performance after long-term alternating heat and cold temperature.
 
Damp heat test purpose: To test the deterioration characteristics of the product when it is subjected to high temperature and high humidity environment, to evaluate the moisture absorption characteristics, dew condensation characteristics of the material, and the storage and use performance of the product in a hot and humid environment.
 
The temperature and humidity cycle test is mainly for instrumentation materials, electricians, electronic products, household appliances, automobile and motorcycle parts, chemical coatings, aerospace products and other related products. It is stored in warm, humid, hot and humid environment. The detection of the adaptability of the environment.
 
Test parameters
 
Test temperature range, rise/fall rate, humidity range, test time, cycle time, exposure time, etc.
 
Performance impact
 
Deformation, peeling, cracking, separation, discoloration, material oxidation, corrosion, expansion, hydrolysis, mildew, mechanical properties, etc.
