DIN EN IEC 63522-48:2025-10

This part of IEC 63522 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 for contact failure rate test of electromechanical elementary relays applied to low-load applications (for example, CC 0, CC 1) and failure rates and failure rate levels at low loads under specified conditions. The standard describes test procedures and evaluation. There are no restrictions on the scope of application of this document. Application of this standard increases investment security for manufacturers and users and provides testing laboratories and manufacturers with defined specifications for testing.
