scope:

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. This part provides criteria to check that closed contacts of a DUT do not fail to open within a specified time, due to, for example, effects of remanence, chemical effects, or high temperature.
