DANSK DSF/PREN IEC 61810-7-17 PDF

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. The standard is to prove the capability of the DUT to function during and/or after several stress situations, that may occur in service, during handling or during transportation. This part comprises test procedures to simulate shock impacts, steady acceleration environments (such as moving vehicles, aircraft and projectiles) as well as vibration conditions. Those procedures provide evidence about the structural integrity of DUTs and their electromechanical design robustness. Based on the chosen test severity, the procedures may also be used to deliberately reveal mechanical weaknesses of DUTs and allow grouping of parts acc. to their stress resistance levels. The tests are mainly intended for specimen without packaging. However, if the packaging is considered an essential part of the specimen, then certain tests like shock tests may be carried out with packaging as well.
