IEC 63522-48:2024

IEC 63522-48:2024 is used for for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combinations of these) and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
This document defines a standard test method for contact failure rate test of electromechanical elementary relays applied to low-load applications (e.g., CC 0, CC 1) and failure rates and failure rate levels at low loads under specified conditions.
