1 Scope
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 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 to investigate the effect of acoustic
noise in conjunction with the operating, releasing and cycling noise of a relay and
the immunity of a relay to acoustic noise.
