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.

This document provides instructions on the methods to be used when designing, selecting, manufacturing, installing, repairing or modifying the aircraft electrical and optical interconnection networks, also called Electrical Wiring Interconnection System (EWIS), and Optical fibre Interconnection Systems (OFIS), subject to the following limitations: - It is recognized that the installation practices contained in this document do not necessarily represent the full requirements for a safe and satisfactory electrical and fibre optic interconnection system. - In the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. However, nothing written in this document overrides the specific requirements of a Design Authority, the Airworthiness Requirements, applicable laws or any regulation from the regulatory authorities, unless a specific exemption has been obtained. This document lists the main relevant European Standards related to EWIS and OFIS in Annex A.

This document specifies the requirements for determining fatigue crack growth rates using corner-crack (CC) test pieces. Crack development is measured using a potential-drop system, and the calculated crack depths can be corrected via marker bands created on the fracture surface during the test. Results are expressed in terms of the crack-tip stress-intensity range (ΔK), with crack depths and test stress level noted.

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 business requirements for processes intended to preserve digital data. NOTE Data are stored and maintained for the purpose of retrievability and usability during the required archiving period. In addition, for the purpose of some business requirements, data are authentically preserved and accessed. This document is intended to allow for different implementations based on a company’s specific business environment. This document is not intended to incorporate company specific requirements and does not dictate specific organizational structures within a company. This document does not specify a design or an implementation of an archive system. Actual implementations can distribute responsibilities or break out functionality differently. This document assumes that all requirements for configuration management of the product data are in place and therefore are not specifically described in this document.
