SIST EN 6049-002:2010

Overview

SIST EN 6049-002:2010 is a European standard under the Aerospace series, providing a comprehensive list of all product standards related to electrical cable protection sleeves made from meta-aramid fibres. Developed by the Aerospace and Defence Industries Association of Europe (ASD-STAN) and approved by CEN, this standard specifically addresses protection sleeves designed for aerospace electrical cable installations. Meta-aramid fibre sleeves are critical components used to safeguard cables and cable bundles from mechanical damage, fire, electromagnetic interference (EMI), and extreme thermal conditions common in aerospace environments.

This standard offers a consolidated reference for all parts of the EN 6049 series, ensuring manufacturers, engineers, and quality managers have a clear overview of relevant product specifications required for aerospace applications.

Key Topics

• Scope of Sleeve Standards: EN 6049-002 outlines all current parts of the EN 6049 series which specify different types of protection sleeves based on construction and intended use, including braided, tubular, expandable, flexible post-installation, self-wrapping, EMI shielded, and fire protection sleeves.
• Meta-Aramid Fibre Use: Focuses on sleeves made from meta-aramid fibres, which provide robust thermal resistance (up to 260 °C depending on the sleeve type), excellent mechanical strength, and fire resistance suited for aerospace electrical installations.
• Temperature Operating Ranges: Defines the temperature limits for each sleeve type to help select materials that endure the demanding aerospace environment (from −55 °C up to 260 °C depending on product).
• Mechanical and Electrical Protection: Differentiates sleeves that offer purely mechanical protection from those providing additional electrical or EMI shielding capabilities.
• Related Product Standards: References relevant EN 6049 parts (such as EN 6049-003 for braided expandable sleeves and EN 6049-009 for fire protection sleeves) and quality assurance standards like EN 9133 for qualification procedures.
• Quality Assurance: Emphasizes the importance of standardized quality management via EN 9133 to ensure aerospace safety compliance and product reliability.

Applications

EN 6049-002 and its associated product standards apply specifically to the aerospace industry, where the protection of electrical cables is critical for safety and operational reliability. Key applications include:

• Aircraft Electrical Systems: Protecting wiring installations from abrasion, thermal damage, fire hazards, and electromagnetic interference.
• Spacecraft and Satellites: Ensuring cables endure extreme temperature fluctuations, mechanical stresses, and high reliability demands in space environments.
• Aerospace Maintenance and Repairs: Offering expandable and high-expandable sleeves for retrofit, repair, and modification of existing cable harnesses.
• High-Temperature Zones: Utilizing fire-resistant and high-temperature self-wrapping sleeves for engine compartments and other heat-prone aerospace areas.
• Electromagnetic Shielding: Employing EMI shielded sleeves to prevent signal interference in avionics and communication cables.

Selecting the correct sleeve type per EN 6049 standards improves cable longevity, enhances system safety, and facilitates compliance with aerospace certification requirements.
