This part of IEC 63522 is used for testing all kind of relays within the scope of technical committee 94 and shall evaluate their ability to perform under expected conditions of transportation, storage and all aspects of operational use. The object of this test is to define a standard test method for electrical contact noise. Note: The measurement electrical contact noise is depending on the relay design as well the complete test setup and therefore influenced by any parameters. It is recommended to define the entire set-up with the customer.
