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.

This document specifies the dimensions, linear resistance, mechanical characteristics, construction and mass of lightweight conductors, normal and tight tolerances, in copper or copper alloy for electrical cables for aerospace applications. It applies to stranded conductors, with a nominal cross-sectional area of 0,15 mm2 to 14 mm2 inclusive. The conductors for thermocouple extension and fire-resistant cables are not covered by this document.

1.1 In Scope The EN 9300-5xx series specifies the methods for long term archiving and retrieval of MBSE data represented as digital models. The characterization of models that are considered in scope of this document and the MBSE process use cases include: - product or system design requirements models; - functional architecture models; - logical architecture models (system structure, arrangement, connectivity, software allocations and controls, and part relationships); - numerically-based system analysis and simulation models, generally regulated 1D control loop models featuring system components and transport elements (tubing, piping, signalling, software); - verification and validation of requirements; - protocol dependent signal or communication networks; - multi-model linking and system parametric models; - system trade study models; - the solution architecture models and data that are needed to implement the system and generate system engineering data for downstream designs. 1.2 Out of Scope The EN 9300-5xx series does not address the original product model design process, or a specific configuration management process for the LOTAR archive. It does not address models depicting part specific technical data (physical materials or detail part standards). It is assumed that these archiving processes are within the scope of other parts of the EN 9300 series such as the 1xx series for CAD, the 2xx series for Product Data Management (PDM) data, or by applying existing alternative industry standards, or existing company business procedures. Typical models and capabilities considered out of scope of this document include: - physical spatial models or composite structures (as described by other LOTAR Parts); - Finite Element and CFD models (as described by other LOTAR Parts); - Product Data Management models (as described by other LOTAR Parts); - electrical circuit boards, or physical wiring parts or systems (described by other LOTAR Parts or standards); - the software development process and software models that are outside of the context of software parts, behaviours, or functions that represent software code within a model; - how to preserve property and access rights, or government acquisition-regulatory controls; - new standards, or major revisions to existing MBSE standards that were not available or applicable prior to the publication of this document.
