Thermal shock
Project Introduction
Thermal shock, that is, the high and low temperature shock test, is to expose the test sample to a continuous alternating environment of high and low temperatures, causing it to experience rapid changes in temperature in a short period of time to assess the product's adaptability to rapid changes in ambient temperature.
Thermal shock test is an indispensable test in the qualification test of equipment design and finalization and the routine test in the batch production stage. In some cases, it can also be used for environmental stress screening test. It can be said that the frequency of application of hot and cold shock test chambers in verifying and improving the environmental adaptability of equipment is second only to vibration and high and low temperature tests.
Test purposes
Thermal shock test mainly verifies the use and storage conditions of samples under rapidly changing conditions of high and low temperatures. It is an indispensable test in the qualification test of equipment design and finalization and the routine test in the batch production stage. In some cases, it can also be used Environmental Stress Screening Test.
Application scope
Hot and cold shock mainly targets electronic products, mechanical parts, and automobile parts.

Specific examples of thermal shock

· Movement between warm indoors and cold outdoors

· Sudden cooling due to rain or cold water

· Turning the power ON and OFF causes the temperature of parts to rise suddenly

· ON/OFF of air conditioning or heating

· Rapid ascent and descent of the aircraft

· Poor manufacturing process causes solder cracks

method standards
Test standard reference: GB/T 2423.22, IEC 60068-2-14, EN 60068-2-14.
testing cost
The price of the thermal shock test is quoted based on the test duration. Products of different sizes use temperature chambers of different sizes. Temperature chambers of different sizes have different test prices, which are calculated based on the duration. In addition, the short test time will involve basic startup fees.
