Temperature aging testing

WebIn accelerated life testing thermal cycling, the temperature applied to the product varies from high to low and these values exceed the normal operating temperature of the product. The aim is to impose mechanical stresses on the product due to the thermal contraction and expansion of the materials. ... Thermal cycling also addresses the aging ... WebAll UV aging can accurately control the temperature to improve accuracy and speed up the testing process. Although the temperature usually does not affect the primary photochemical reaction, it affects the speed of any subsequent reaction. Therefore, the temperature control capability of the UV aging chamber is essential for UV aging testing.
