To prove it is suitable and convincing it is the best standard of the industry, we have done one test through third-party lab.

Test description:ambient temperature:23℃,relative humidity:50%
The stress relaxation testing was performed according to GB/T 1685-2008 method A.
Estimation of a lifetime by Stress relaxation testing evaluate the test result according to Arrhenius
based on GB/T 20028-2005.
