Overview

EN 3475-606:2024 is a European standard that specifies the test method for evaluating the wicking characteristics of wires and cables insulated with textile braid for aerospace applications. Developed by CEN and ASD-STAN, this standard forms part 606 of the aerospace series related to electrical cables used in aircraft. It addresses the critical need to assess the extent to which moisture can travel along the textile braid insulation, ensuring cable reliability and safety in demanding aviation environments.

This test method is intended to be used in conjunction with EN 3475-100, which covers general test procedures for aerospace electrical cables. By providing a precise measurement technique for wicking in textile braid insulation, EN 3475-606:2024 supports manufacturers, engineers, and quality assurance teams in maintaining aerospace cable integrity.

Key Topics

• Wicking Test Description
  The standard defines a laboratory method to measure how far a rhodamine B dye solution travels by capillary action within the textile braid insulation of electrical cables.

• Specimen Preparation
  Samples of wire or cable are cut to a standardized length (minimum 155 mm), and their ends are sealed using heat-shrink sleeves and, if needed, epoxy resin to prevent fluid ingress from non-tested ends.

• Test Solution Composition
  The dye solution is prepared using precise quantities of rhodamine B dye, ethyl alcohol, aerosol OT surfactant, and distilled water to ensure consistency and reproducibility.

• Testing Procedure
  The sealed specimen is immersed in the dye solution for 24 hours in a controlled environment. Subsequently, the wicking distance-the extent to which the dye travels through the textile braid-is measured in millimeters.

• Measurement and Requirements
  Only dye penetration along the textile braid insulation itself is considered; penetration between insulation layers or conductor is excluded. The allowable maximum wicking distance is defined by the product-specific standards to ensure cable performance criteria are met.

Applications

• Aerospace Electrical Cables
  The wicking test is essential for aerospace wire and cable manufacturers to verify insulation quality and resistance to moisture ingress that can compromise electrical performance and safety.

• Quality Assurance and Product Development
  Engineering teams utilize EN 3475-606:2024 to validate new insulation materials and production methods, ensuring compliance with aviation industry requirements.

• Maintenance and Inspection
  Aircraft maintenance organizations can adopt this method for periodic cable testing, to detect early signs of insulation degradation caused by environmental factors.

• Certification and Compliance
  Compliance with this test is often a prerequisite for aerospace certifications, as it helps demonstrate adherence to rigorous international electrical cable performance standards.
