Abstract

1 Scope 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. This document provides test methods to ensure that the connection between an earthing terminal and parts required to be connected thereto is of low resistance.
