Environmental Performance

Warm experiment: 

Temperature 55℃±2℃, humidity 90%-95% environment for 48 hours, room temperature for 12 hours, no abnormal performance

Temperature resistance: 

Take 80℃±2℃, 12 hours → normal temperature for 4 hours → 30℃±2℃; 12 hours → normal temperature for 4 hours as a cycle, do 3 cycle tests, the performance is normal

High temperature resistance: 

After 12 hours at 55℃±2℃, there is no abnormal performance

Low temperature resistance: 

-30℃±2℃ for 12 hours, no abnormal performance

Salt spray resistance: 

Meet the NSS 48-hour requirement, with no abnormal performance
