ČSN EN IEC 63522-9

This part of IEC 63522 is used for testing all kind of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. NOTE - Examples for electrical relays in the sense of this document include electromechanical relays, reed relays, reed contacts, reed switches, solid state relays, time relays and technology combinations of these. It defines standard test methods to determine the ability of the relay to withstand certain climatic test conditions, a sequence of such climatic test conditions or climatic storage conditions.
