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 provides tests to ensure that a relay is suitable for use when subjected to contamination by fluids found in aerospace applications and similar. This test applies to RT III to RT V relays only.
