This part of IEC 61810-7 is used for testing all kind of relays within the scope of technical committee 94 and shall evaluate their ability to perform under expected conditions of transportation, storage and all aspects of operational use. The tests stated here within shall be done with test conditions and appropriate severities, as well as suitable measurements conditions. The object of this test is to define a standard test method to ensure that the DUT performs satisfactorily at its specified energization values throughout the defined temperature range. It is used to determine whether internal moisture has an adverse effect on certain properties of the DUT. This test is only applicable to RT III, RT IV and RT V products, i.e. wash tight, sealed and hermetically sealed DUTs.
