1. Low temperature storage test: The test temperature is -55 °C or according to product standards (or technical documents). The test time is 12 hours after the test sample has reached temperature stability or as specified by the product standard (or technical documentation).
2. Low temperature work test: The test temperature of the low temperature test chamber is the lowest working environment temperature of the test sample, and the corresponding severity level can be selected according to -55, -40, -25, -15, -5, +5 °C. The test time is that the test sample reaches temperature stability under non-operating conditions, and then the test sample is started to work until the test sample reaches temperature stability or the working time specified by the product standard (or technical file).
