Electrical relays. Tests and measurements. Internal moisture | Status: Current

1 Scope This document is used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combinations of these) and evaluates their ability to perform under expected conditions of transportation, storage, and all aspects of operational use. This document defines a standard test method to provoke internal moisture inside relays by different methods. The device under test (DUT) is tested at its specified energization values throughout the defined temperature range. The test methods in this document are applicable to RT III, RT IV and RT V products only, i.e., wash-tight, sealed, and hermetically sealed DUTs.
