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 evaluate the switching function of the device under test (DUT) at specified energization values throughout the defined temperature range. This test method is part of the general DUT type test according to IEC 61810‑1:2015, Table 3.
