IEC 63522-45 Ed. 1.0 b:2025

This part of IEC 63522 is used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combination of these) and evaluates their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
This test defines a standard test method for maximum frequency of operation to ensure the mechanical, electrical durability and contact failure rate test of electromechanical elementary relays.
