This part of IEC 61810 is used for testing all kind of relays within the scope of IEC technical committee 94 and shall evaluate their ability to perform under expected conditions of transportation, storage and all aspects of operational use. This document is to define a standard test method for contact failure rate test of electromechanical elementary relays, reed relays, reed switches and similar components applied to low-load applications (e.g., CC 0, CC 1). This document also defines cycle-related failure rates and failure rate levels at minimum switching loads under specified conditions.
