BS EN IEC 63522-12:2025

This standard BS EN IEC 63522-12:2025 Electrical relays. Tests and measurements is classified in these ICS categories:

• 29.120.70 Relays

IEC 63522-12:2025 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 document defines a standard test method to provoke internal moisture inside relays by different methods. The device under test (DUT) is tested at its specified energization values throughout the defined temperature range. The test methods in this document are applicable to RT III, RT IV and RT V products only, i.e., wash-tight, sealed, and hermetically sealed DUTs.
