High and low temperature test

This test is used to determine the product's suitability for storage, transportation, and use in high-temperature climate conditions. The severity of the test depends on the temperature of the high temperature and the duration of the exposure.

Test Standard Reference: GB/T 2423.2, IEC 60068-2-2, IEIA 364, MIL-STD-810F

Common test parameters: +55°C+ -2°C, duration 4H (minimum)

Low temperature test:

The purpose of the cryogenic test is to determine the suitability of military and civilian equipment for storage and operation at low temperatures.

Reference standards: IEC 60068-2-1 (GB/T2423.1), EIA634, MIL-STD-810F

Common test parameters: -10°C+-3°C, duration 4H (minimum)

Simulated severe cold area use: -40°C, duration 4H (minimum)
