IEC 63522-38 Ed. 1.0 b:2025

Full Description

This part of IEC 63522 is used for testing all kinds of electrical relays and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use.

NOTE 1 Examples for electrical relays in the sense of this document include electromechanical relays, reed relays, reed contacts, reed switches, solid state relays, time relays and technology combinations of these.

This document defines a standard test method for mechanical interlock.

This test is applicable to the elementary relays which have the mechanical interlocking mechanism.

NOTE 2 The electrical interlocking is not applicable to this test.
