Overview

EN 4674-001:2017 is a European Standard developed by CEN specifying the technical requirements for self-wrapping shielding (EMI) protective sleeves used in aerospace applications. The standard defines general characteristics, qualification, and acceptance criteria for these sleeves, which are designed to provide electromagnetic interference (EMI) shielding for electrical cables and cable bundles installed in aircraft and other aerospace systems. This specification aims to ensure that protective sleeves meet stringent aerospace demands regarding mechanical flexibility, thermal resistance, and environmental durability.

Key Topics

  • Scope and Purpose
    The standard covers tubular self-wrapping EMI protective sleeves that can be installed easily and removed without damage. These sleeves protect cable bundles from electromagnetic interference and are suitable for both pressurized and non-pressurized aerospace environments.

  • Materials and Construction
    EMI screens are composed of plated copper wires or wire groups woven with aerospace-grade mono- or multi-filament strands. Protective tapes may cover the internal side to enhance mechanical protection. Copper strands adhere to ASTM specifications for conductivity and strength, with plating options including tin, silver, and nickel to provide corrosion resistance and durability.

  • Design Requirements
    Sleeves must provide effective EMI shielding without damaging cables they protect. Key properties include:

    • Resistance to temperature extremes and fluid exposure
    • Mechanical flexibility aligned with aerospace cable bend radius standards (e.g., EN 3197)
    • Flame resistance and low smoke/toxicity characteristics in accordance with aerospace regulations
    • Electrical continuity ensured by longitudinal copper warps and optional transverse strands
  • Installation Parameters
    Proper sleeve twisting (two 360° turns per meter) is mandatory to prevent sleeve opening or cable exit. Sleeves include identification tracer lines indicating minimum overlap for maximum bundle diameter compatibility. Installation tools that do not damage sleeves or cables are permitted.

  • Qualification and Testing
    EN 4674-001:2017 mandates rigorous qualification tests for acceptance, covering:

    • Visual inspection
    • Dimensional conformity
    • Environmental exposures (sunlight, high temperature, fluid resistance)
    • Mechanical tests including bending, vibration, dynamic cut-through resistance
    • Flammability and mold resistance tests
      These tests ensure sleeves maintain EMI protection and physical integrity during operational life.

Applications

The standard applies to aerospace electrical systems requiring EMI protection such as:

  • Aircraft wiring harnesses in both pressurized cabin and external environments
  • Shielding of avionics cables against electromagnetic interference
  • Protection of cable bundles where installation flexibility and ease of maintenance are critical
  • Use in aerospace environments with demanding temperature, vibratory, and flammability constraints

By adhering to EN 4674-001:2017, aerospace manufacturers ensure the integrity and electromagnetic compatibility of critical wiring installations, improving overall system reliability and safety.

This standard supports effective EMI management and contributes to the reliable operation of advanced aircraft electrical systems.
