1.1       This document is intended to be used to assign part classifications across the aviation industries that use AM to produce parts. 1.2       This document is applicable to all AM technologies defined in ISO/ASTM 52900 used in aviation. 1.3       This document is intended to be used to establish a metric for AM parts in downstream documents. 1.4       This document is not intended to establish criteria for any downstream processes, but rather to establish a metric that these processes can use. 1.5       The part classification metric could be utilized by the engineering, procurement, non-destructive inspection, testing, qualification, or certification processes used for AM aviation parts. 1.6       The classification scheme in this document establishes a consistent methodology to define and communicate the consequence of failure associated with AM aviation parts. 1.7       This document is not intended to supersede the requirements and definitions of the applicable regulations or policies, including but not limited to the ones listed in Annex A1. 1.8       Tables A.1.1-A.1.3 align the existing regulations and guidance with the four part classes established herein. However, this alignment should not be construed as an alignment of the existing regulations to each other. 1.9       The material or process, or both, in general does not affect the consequence of failure of a part, therefore the classification scheme defined in this document may be used outside AM. 1.10    The user of this document should not assume regulators’ endorsement of this document as accepted mean of compliance. 1.11    This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this document to establish appropriate safety, health, and environmental documents and determine the applicability of regulatory limitations prior to use. 1.12    This document was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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.
