This document specifies the characteristics, test methods, qualification and acceptance conditions of single and multicore electric cables, without jackets, for general purpose with conductors in copper or copper alloy, intended for installation in aircraft circuits. The insulation of these cables is designed to withstand aircraft voltages at a frequency not exceeding 2 000 Hz. Unless specified by individual product standards the maximum demonstrated A.C. voltage of rating of these cables is 115 V RMS (phase to neutral) and 200 V RMS (phase to phase). They are divided into types, the characteristics of which are given in the product standards. Unless otherwise specified in the product standard, the tests defined in this document apply.

This document specifies the requirements for offset cruciform recess pan head screws with relieved shank and long thread in heat resisting steel FE-PA92HT, silver plated, tensile strength class 900 MPa at room temperature. The maximum test temperature of the material is 650 °C.

This document specifies the characteristics of bolts, normal hexagonal head, coarse tolerance normal shank, medium length thread, in heat resisting nickel base alloy, aluminium IVD coated. Classification: 1 250 MPa / 425 °C

This document specifies the test method to determine the flow behaviour of structural adhesives supplied in the form of adhesive films. This document is applicable: — to check the flow behaviour of adhesives; — for determining the alteration in flow behaviour of adhesives depending on storage time; — for determining environmental influences on flow behaviour.

The EN 4500 series specifies the rules for the drafting and presentation of metallic material standards for aerospace applications. This Part 002 specifies the “Specific rules for aluminium, aluminium alloys and magnesium alloys”.

The EN 4500 series specifies the rules for the drafting and presentation of metallic material standards for aerospace applications. This Part 005 specifies the “Specific rules for steels”.

This document specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programs and groups for rectangular connectors with one or multiple removable modules, intended for use in a temperature range from −55 °C to 175 °C continuous. This family of connectors is particularly suitable for aeronautic use in zones of severe environmental conditions on board aircraft, applying EN 2282. The maximum in-service temperature can be limited by maximum temperature of contacts.

This document specifies the electrolytic cadmium plating of parts and fasteners in steel of tensile strength UTS ≤ 1 450 MPa, copper, copper alloys and nickel alloys, whose temperature in service does not exceed 235 °C.

This document specifies a method of measuring the tensile properties of stranded conductors, single strands, solid conductors and braids. When required, it can be used also on insulated wires and cables after removing the insulation. It is intended to be used together with EN 3475-100.
