Overview

SIST EN 4608-003:2012 is a European standard developed by CEN that specifies the technical requirements for lightweight, fire resistant electrical cables used in aerospace applications. These cables are designed for on-board electrical systems of aircraft, with operational temperature capabilities ranging from -65 °C up to 260 °C. A key feature of this standard is that the cables are UV laser printable in accordance with EN 3838, enabling durable and high-precision marking essential for traceability and maintenance in aerospace environments.

The cables covered in EN 4608-003 are screened (braided) and jacketed, available in single and twisted multicore assembly configurations. They are intended to deliver reliable electrical performance while meeting stringent fire resistance and durability criteria demanded by the aerospace industry.

Key Topics

• Cable Construction and Materials
  Cables are constructed with nickel-plated copper braided screens and sintered wrapped PTFE outer jackets, ensuring fire resistance and mechanical protection. The cores meet specifications outlined in EN 2346-004, with 1 to 3 cores twisted together as per EN 4608-001.

• Operating Conditions
  Designed for extreme environments, cables withstand continuous use in temperatures ranging from -65 °C to 260 °C, and support operating voltages up to 600 V AC and frequencies up to 2000 Hz.

• Fire Resistance and Safety
  These cables exhibit fire resistance tested via EN 3475 series, including flammability tests with extinction times below 3 seconds and thermal shock resistance, supporting aircraft safety requirements.

• UV Laser Printability
  The outer PTFE jacket allows UV laser marking compliant with EN 3838, enabling permanent and high-contrast cable identification crucial for aerospace quality assurance and maintenance.

• Performance Testing and Quality Assurance
  The standard mandates extensive testing such as electrical resistance, voltage proof, bending, cold bend tests, abrasion resistance, and dynamic cut-through. Quality assurance aligns with EN 9133 to maintain consistent manufacturing standards.

Applications

EN 4608-003 cables are primarily used in aerospace electrical systems where weight, fire safety, and reliability are critical. Typical applications include:

• On-board wiring for commercial and military aircraft electrical systems
• Signal and power transmission cables requiring fire resistant properties
• Environments expecting exposure to wide temperature ranges and mechanical stresses
• Aerospace assemblies where cable traceability and durability are key, enabled by UV laser print marking

The lightweight construction optimizes aircraft weight without compromising safety or electrical performance, making these cables suitable for high-demand aerospace environments.
