ČSN EN IEC 63522-6

This part of lEC 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 measure contact-circuit resistance or voltage drop.
