Equipment summary:
Low Temperature Chamber is mainly testing the material performance in low-temperature, such as electrical, electronic products, as well as their original devices. The testing equipment is mainly made according to the national standard and user-defined requirements, it simulate the environment to test proformance of material as well as other relevant characteristics of physical at low temperature. Through testing to determine product performance whether it is still be able to meet the intended requirements.

Corresponding standard:
1. GB 10589-89 low temperature testing condition
2. GB/T5170.2-1996 basic parameters of environmental testing method for Electrical and electronic products,
3. GB2423.1-89 The basic test regulation for electrical and electronic products, Test A: low-temperature test method
