DIN EN IEC 63522-15:2025-09

This document is used 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 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. This document deals with test methods and evaluation. There are no restrictions on the scope of application of this document. Application of this standard provides manufacturers and users with greater investment security, while testing laboratories and manufacturers are given defined specifications for testing.
