BS EN IEC 63522-15:2025

This standard BS EN IEC 63522-15:2025 Electrical relays. Tests and measurements is classified in these ICS categories:

• 29.120.70 Relays

IEC 63522-15:2024 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 document defines a standard test method that applies defined loads to relay terminals (direct axial pulls, bending or twisting) as they can be present in assembled configurations or during handling. In addition, it covers torque stress for nuts and threaded terminals as they are likely to be experienced during normal assembly operations.
