This standard specifies the general requirements for electromagnetic relays (including the reliability index "ER") used in electrical systems with a main contact rated current (resistive) of 2 A and above 2 A. The rated current of the auxiliary contact can be less than 2 A Amperes. Relays (hereinafter referred to as products) that comply with this standard should be able to meet the electrical and environmental requirements when directly installed on aircraft, missiles, spacecraft, spacecraft and other aircraft or ground equipment and ships. Product-specific standards (see 3.1).
