EN 2714-003:2005

Overview

The EN 2714-003:2005 standard is a crucial European standard published by CEN, focusing on aerospace-grade electrical cables. It specifies the requirements for single and multicore, screened (spiral) and jacketed electrical cables designed for general-purpose use within aircraft electrical systems. These cables are engineered to operate reliably in extreme temperature environments ranging from -55 °C to 260 °C. The standard also mandates that the cables be suitable for ink jet printable markings and hot stamp printing compliant with EN 3838, ensuring clear and durable identification important for aerospace safety and maintenance.

This product standard guarantees that cables meet stringent quality criteria for performance, safety, and durability under the demanding conditions encountered in aerospace applications.

Key Topics

• Cable Construction and Materials:

  • Cores comprise single or multicore configurations (1 to 4 cores) without fillers.
  • Nickel-plated copper stranded spiral screen per EN 2083.
  • Outer jackets composed of polyimide layers combined with fluorocarbon and polytetrafluoroethylene coatings for thermal and mechanical protection.
  • Cable design ensures resistance to extreme temperatures and environmental stress during aircraft operation.

• Operating Temperature Range:

  • Stable performance assured from -55 °C to 260 °C, suitable for harsh aerospace environments.

• Marking and Identification:

  • Ink jet printable surface for efficient product marking.
  • Hot stamp printing capability with marking standards set by EN 3838 for traceability and compliance.

• Testing and Quality Assurance:

  • Compliance with comprehensive testing requirements from EN 3475-100, covering electrical, mechanical, and environmental performance such as resistance to aging, thermal shock, bending, flammability, and tensile strength.
  • Quality systems aligned with aerospace industry standards such as EN 9133 ensure product consistency and traceability.

• Cable Codes and Designation:

  • Detailed classification and coding system for specifying the number of cores, section size, and color coding according to EN 2714-002 and internal tables.

Applications

• On-board Aircraft Electrical Systems:
  The standard’s cables are designed primarily for use within aircraft electrical systems that require high reliability and durability under temperature extremes - from cold high-altitude conditions to hot areas near engines or electronics.

• General Aerospace Electrical Installations:
  Ideal for harnesses, signal transmission, and power delivery systems where screened and jacketed cables prevent electromagnetic interference, ensuring stable operation of avionics and control systems.

• Maintenance and Identification:
  Markings enabled by this standard improve maintenance efficiency by allowing clear and precise identification throughout the aircraft’s lifecycle.
