scope:

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. The object of this test is to define a standard test method for maximum frequency of operation to ensure the mechanical, electrical durability and contact failure rate test of electromechanical elementary relays. This document can be used in conjunction with relevant Part 7 series (e.g., mechanical endurance) applying specified conditions as frequency of operation (in number of cycles per hour).
