Hot and cold shock
Project introduction
Hot and cold shock, also known as high and low temperature shock test, is to expose the test sample to a continuous alternating environment of high and low temperature, so that it experiences a sharp change in temperature in a short period of time, and to assess the adaptability of the product to the sharp change in ambient temperature.
Hot and cold shock test is an indispensable test in the identification test of equipment design finalization and routine test in the batch production stage, and 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 chamber in verifying and improving the environmental adaptability of equipment is second only to vibration and high and low temperature test.
Test purpose
Hot and cold shock test mainly verifies the use and storage conditions of samples under the conditions of rapid changes in high and low temperatures. It is an indispensable test in the identification test of equipment design finalization and routine test in the batch production stage, and in some cases it can also be used for environmental stress screening test.
Application scope
Hot and cold shock is mainly for electronic products, mechanical parts, and automotive parts.

Specific examples of thermal shock

· Moving between warm indoor and cold outdoor

· Sudden cooling due to rain or cold water

· Sudden rise in component temperature due to power on and off

· Turning air conditioner or heater on/off

· Rapid ascent and descent of an aircraft

· Solder cracking due to poor process

Method standard
Test standard reference: GB/T 2423.22, IEC 60068-2-14, EN 60068-2-14.
Testing fee
The price of thermal shock test is quoted according to the test duration. Different sizes of products use different sizes of temperature chambers. Different sizes of temperature chambers have different test prices, calculated according to the duration. In addition, short test time will involve basic startup fees.
