Termal Shock Test is performed to observe the resistance of the sample to sudden temperature changes. The performance of the sample is observed during or at the end of the Thermal Shock Test, and any errors that occur are recorded.

Tests can be carried out in accordance with all military and civilian standards that meet the technical specifications of air conditioning cabins. Temperature shock testing is used to determine whether the material can withstand sudden temperature changes in the temperature of the surrounding atmosphere without experiencing physical damage or performance degradation. Sudden changes are defined as air temperature changes of more than 10°C within one minute. It evaluates how materials respond to temperature drops and spikes over a one-minute period.

The material or equipment must be stored between climate-controlled environmental areas and extremely hot outdoor conditions, or with a heated enclosure in cold areas dış the effect that occurs during transfer between ambient cold weather conditions is determined by this test.

Thermal shocks cause disintegration of plastic materials, bonding problems of moving parts, cracks caused by differential expansion of dissimilar materials, bond failures in integrated circuits, or electronic or mechanical failures due to rapid water or frost formation.

The MIL-STD-810G Method 503.5 standard includes a test procedure with four variations. It uses constant temperature in each of the extreme shock conditions because in many cases the thermal shock itself outweighs any other thermal effects.
