Overview

The EN 6059-203:2024 standard, published by CEN, is part of the aerospace series addressing the installation and protection of electrical cables. This particular part-Part 203: Coverage-specifies precise test methods for measuring and calculating the coverage of protection sleeves used on electrical cables and cable bundles in aerospace applications. It is designed to be applied in conjunction with EN 6059-100 to ensure comprehensive assessment of protection sleeve performance.

Protection sleeves are critical for safeguarding aerospace electrical wiring against mechanical damage, abrasion, and environmental hazards. Accurate measurement of sleeve coverage ensures reliability, safety, and compliance within aerospace electrical systems.

Key Topics

• Scope and Purpose:
  Defines standardized methods to determine coverage percentage of protective sleeves installed over aerospace electrical cables.

• Test Methods:
  Two main methods are detailed for assessing sleeve coverage based on sleeve fabric complexity:

  • Method 1: Theoretical Calculation (for braids and woven sleeves with plain weave structures)
  • Method 2: Optical Method (for complex textile fabrics and confirming Method 1 results)

• Specimen Preparation:
  Samples must be at least 200 mm in length, with tubular sleeves cut open longitudinally to prepare flat specimens, ensuring accurate testing conditions.

• Measuring Techniques and Equipment:

  • Visual counting, micrometers, optical microscopes, and software-controlled image analysis
  • Measurement of yarn diameters, counts, weave patterns, and void areas between yarns

• Coverage Calculation Formulas:

  • Covers different textile structures using geometric parameters, yarn counts, and optical measurements to compute percent coverage.

• Requirements:
  Test results must comply with the relevant product standards to guarantee sleeve protective performance.

Applications

The EN 6059-203:2024 standard is vital for aerospace manufacturers, quality assurance teams, and engineers responsible for:

• Electrical Cable Assembly:
  Ensuring protection sleeves fully cover cable bundles to meet stringent aerospace safety criteria.

• Quality Control:
  Verifying the integrity and coverage of braids and woven textile sleeves that protect electrical systems in aircraft and spacecraft.

• Design Validation:
  Assisting product developers in selecting and testing suitable protection sleeves for aerospace electrical installations.

• Compliance and Certification:
  Meeting harmonized European and international requirements for aerospace electrical equipment installation to facilitate market access and regulatory approval.

Related Standards

• EN 6059-100: Aerospace series - Electrical cables, installation - Protection sleeves - Test methods - Part 100: General
  Provides overarching principles and general test methods to complement Part 203.
