EN 6059-202:2016

Overview

EN 6059-202:2016 is a European Standard developed by CEN that specifies the test methods for assessing the dimensions and mass of protection sleeves used for electrical cables and cable bundles in aerospace installations. This standard forms part of the broader EN 6059 series on aerospace electrical cable installations, focusing specifically on ensuring the quality, consistency, and compliance of protection sleeves regarding their size and weight characteristics. It is intended to be used alongside EN 6059-100, which provides general test methods for protection sleeves.

Key Topics

• Scope and Purpose
  Defines a standardized method for examining protection sleeve dimensions and mass to guarantee functional integrity and installation compatibility in aerospace contexts.

• Normative References
  References critical documents including:

  • EN 6059-100: General test methods for protection sleeves
  • EN 6059-401: Test methods for expansion range of protection sleeves

• Required Equipment
  Specifies precise instruments for testing such as:

  • Electronic scales with ±0.05 g accuracy for mass measurement
  • Mandrels of specified diameters and lengths for dimensional checks
  • Micrometres with ±0.05 mm accuracy or disk micrometres for measuring the thickness of fabrics and foils

• Test Procedures

  • Measurement of delivered diameter both before and after application onto mandrels
  • Use of tape to ensure full contact between sleeve and mandrel during measurement
  • Measurement of other relevant dimensions on sleeves in their delivered condition
  • Mass testing on specimens at least 0.5 meters long, with a result expressed in grams per meter (g/m)

• Requirements and Compliance

  • Maximum allowable differences in sleeve length before and after mandrel application must comply with product standards
  • All other dimensional requirements and mass tolerances must align precisely with the product specifications to ensure aerospace-grade reliability

Applications

EN 6059-202:2016 is critical for organizations in the aerospace sector involved in manufacturing, testing, and installing electrical cable protection sleeves. It underscores:

• Quality Assurance
  Ensures protection sleeves meet strict aerospace requirements for dimensions and mass, a key factor in reliable cable installation and long-term durability.

• Standardized Testing
  Facilitates uniform testing procedures across aerospace suppliers and system integrators, enabling compatibility and compliance with international aerospace standards.

• Safety and Performance
  Proper dimension and mass control of protection sleeves help maintain system integrity, protecting cables from mechanical stresses and environmental hazards in aircraft and spacecraft.

• Regulatory Compliance
  Supports manufacturers in meeting European aerospace regulations and harmonizes testing benchmarks across multiple countries.
