Electrical relays. Tests and measurements - Contact sticking (delayed release)
Electrical relays. Tests and measurements - Contact sticking (delayed release)
1 Scope This document 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 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 to determine contact sticking of relays as part of the normal service life, i.e., devices under test (DUTs) fail to open within a specified time, due to, for example, effects of remanence, chemical effects, or high temperature. It does not cover contact sticking during or after electrical endurance testing or due to other validation tests for relays.
