Overview
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. This document defines a standard test method to determine contact sticking of relays as part of the normal service life, that is 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. The standard describes the tests and evaluation. Application of the standard enhances investment security for manufacturers and users and provides testing laboratories and manufacturers with defined specifications for testing.
