2 Zone Thermal Shock

Two temperature zone method: specimen moving with the basket

The aim of these tests is to check the behavior of the product when it undergoes a thermal shock; rapid temperature changes from extremely high temperature and low temperature in short time.

In these cases, the sample may cool or heat up with different speeds in different parts depending on the material. If this corresponds to large increases or contraction in volume, the material could suffer large mechanical stresses, leading to failure and we can identify defective components or infantile mortality for electronic components.

The sample is placed inside a movable basket which carries it from the cold compartment to the hot compartment and vice versa for a large number of cycles. These chambers have two or more test compartments and the passage of the sample from one to the other is carried out very quickly (usually within 10 seconds).

The temperature of the test compartments and the testing methods depend on the requirements of the standard which defines the specific cycle to be performed.

Complies to national and international standards: IEC 60068-2-1-1990, IEC 60068-2-2-1974, IEC 60068-2-14-1984
