Climatic testing of electrical components

The electrical conductance of a material may vary with moisture content. Therefore the quality of an electrical component may degrade due to the diffusion of moisture into the material from the atmosphere. For this reason an international standard was devised for materials to be used as electrical components. Details of testing methods are presented in the Specification CEI/IEC 749:1996. The test methods are designed to provide accelerated testing criteria which correspond to conditions found in normal use of electrical components.
