CSN EN IEC 63522-27

CSN EN IEC 63522-27 This part of IEC 63522 is used for testing all kinds of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use. NOTE 1 - 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. This document defines a standard test method for electrical contact noise. NOTE 2 - The measurement of electrical contact noise depends on the relay design as well as the complete test setup and is therefore influenced by many parameters. Defining the entire set-up with the customer is effective for electrical contact noise measurement.
