ASD-STAN/D 2/WG 4 - Relays, Switches, Push-Buttons

This document specifies the characteristics of three-pole circuit breakers, temperature compensated with a rated current from 1 A to 25 A, used in aircraft on-board circuits at a temperature between −55 °C and 125 °C for ratings ≤ 15 A and −55 °C to 90 °C for ratings > 15 A and at an altitude of 22 000 m max.
These circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action “trip-free” tripping.
They will continue to function up to the short-circuit current.

This document specifies the requirements and test procedures of switching devices for use in aircraft
electrical systems to EN 2282.

This document specifies characteristics for 10 A aerospace relays with the following variations of mounting means (e.g. vertical, horizontal), terminal styles (e.g. hooks, pins for soldering, pins for sockets) the associated finishing (e.g. tin plated, gold plated) and coil voltages (e.g. 6 VDC 12 VDC 28 VDC 48 VDC, 115 VAC) for relays with 2, 4 or 6 poles and with or without internal suppressors or LIE protection.
The built-in suppressor limits the voltage transients resulting from the electrical power shut off.
The relay sockets are not described in this document.

This document specifies the test procedures of electromechanical all-or-nothing relays for use in aircraft electrical systems to EN 2282.
This document represents the aeronautical version of the standard EN 116000-3 from which it draws inspiration.

This document specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programs and groups for non-latching electromagnetic, hermetically sealed relays intended for use in a temperature range from - 55 °C to 125 °C continuous.
