This standard specifies the test content, procedures and methods for small general-purpose electromagnetic relays. This standard is applicable to the testing of non-sealed small general-purpose electromagnetic relays that control or switch AC voltages below 380V or DC voltages below 220V and currents below 20A. This standard is a general basic test and measurement procedure for relays in the above range. It can also be quoted for relays with or without relays that do not fall into the above range, but the scope and regulations cited must be specifically stated in the relay product standard.
