Cold and Heat Shock - Project Introduction
Cold and hot shock, also known as high and low temperature shock test, involves exposing the test sample to continuous alternating environments of high and low temperatures, causing it to experience rapid temperature changes in a short period. This assesses the product's adaptability to rapid changes in surrounding environmental temperatures.
The cold and hot shock test is an indispensable qualification test during the equipment design phase and routine tests during the mass production stage, and can also be used for environmental stress screening tests in some cases. It can be said that the cold and hot shock test chamber is only second to vibration and high-temperature and low-temperature tests in terms of frequency of application in verifying and improving the environmental adaptability of equipment.
Purpose of the Test
The cold and hot shock test primarily verifies the performance and storage conditions of samples under rapid changes in high and low temperatures. It is an indispensable qualification test for equipment design confirmation and a routine test during the mass production phase. In some cases, it can also be used for environmental stress screening tests.
Application Scope
The cold and heat shock test primarily targets electronic products, mechanical components, and automotive parts.
Specific instances of cold and heat shock
· Transition from cozy indoors to the chilly outdoors
· Sudden cooling due to rain or cold water
· Sudden temperature rise of components due to power ON and OFF
· ON/OFF for Air Conditioning or Heating
The rapid ascent and descent of the aircraft.
Process defects lead to solder cracking
Method Standards
Reference Standards: GB/T 2423.22, IEC 60068-2-14, EN 60068-2-14.
Test Fees
The price for cold and heat shock testing is quoted based on the duration of the test. Different sizes of products correspond to different-sized temperature chambers, and each size of temperature chamber has a different testing price, calculated by duration. Additionally, short testing times may incur basic startup fees.
