This standard stipulates the following content with or without the external dimensions of general-purpose relays, the terminal and the configuration dimensions of the mounting parts: Definition (Chapter 2); Basic modulus and recommended multiples (Chapter 3); External dimensions, using the basic modulus Integer multiples; For socket-mounted relays, the height of the socket is also included; All dimensions given in this standard are in millimeters (mm). This standard applies to all structural types (such as electromechanical, electronic, reed, etc., also including socket-mounted, printed circuit board and other types described in Chapter 6 of this standard) with or without common relay. This standard does not apply to relays included in the ISO (TC20: Aviation and Spacecraft) standard, nor does it apply to the internal structure of the relay and the dimensions of the terminals and mounting parts.
