Difference between temperature shock test and temperature change test

Temperature shock test : This test is characterized by initial testing of the product performance and final testing of the product before and after the test to determine whether the product can withstand rapid changes in temperature, and does not require the product to work during temperature changes and meet performance requirements. The high and low temperature conversion of the high and low temperature box during the test generally stipulates that the conversion time is less than 5 minutes (this is also the index required for the measurement).
Temperature Change Test : A test to assess the resistance and normal working capacity of a product during temperature changes. A test chamber is used to limit the rate of temperature change. Such as: 10 ° C / min 15 ° C / min 20 ° C / min
