The various materials in a component can have different coefficients of expansion, resulting in thermal stresses and premature failure. Constant temperature operation is often not the cause for failure. More commonly it is the stressing induced by temperature cycling which does the damage. Combine that with condensation and the potential for shortened life can be easily anticipated . Well designed and manufactured products can withstand the repeated stress reversals of heating and cooling without failure. Conversely incompatible materials can result in premature failure of otherwise well made components.

Applications:

Climatic chambers are widely used in industries such as aerospace, automotive, electronics, pharmaceutical and marine industry to demonstrate that products will perform under storage, transportation and operation conditions.

Sample handling requirements:

A typical sample will be a complete finished product, in the form it will be when subjected to harsh environment conditions. The component size is limited to the size of the chamber on the testing rig (typically no larger than 1m3)
