Overview

EN 3475-513:2025 is a CEN aerospace test-method standard that specifies procedures to evaluate the deformation resistance of coaxial, quadrax and databus cables after installation with plastic cable ties. Intended for use together with EN 3475-100, this standard ensures that cable harnessing practices do not compromise electrical performance or signal integrity in aircraft systems.

Key Topics

• Scope and purpose: Tests focus on performance changes induced by plastic cable ties on key cable types: coaxial, quadrax and databus.
• Specimen preparation: Detailed specimen lengths and the number/type of ties are specified (examples in the standard: 2 000 mm and 2,2 m specimens for coaxial methods, 20 m for quadrax). Plastic ties conform to EN 4056-003.
• Cable tie application: A calibrated cable tie gun set to 75 N is required for tie installation (corrected value in this edition).
• Thermal conditioning: Where applicable, tied samples are stored for 8 h at (130 ± 5) °C in an air convection oven, then cooled 4–6 h to ambient before final measurements.
• Electrical measurements:
  • Coaxial: impedance measured per EN 3475-805; Method A limits impedance deviation to ≤ 5 %.
  • Coaxial Method B: attenuation and VSWR per EN 3475-806 and EN 3475-812; loop geometry ~160 mm internal diameter.
  • Quadrax: crosstalk per EN 3475-808 with mandrel and minimum bend radius of 5× outer diameter during conditioning.
  • Databus: method sequence and conditioning addressing channel performance and integrity.

Applications

This standard is practically valuable for:

• Cable manufacturers - to validate harnessing robustness and produce compliant product data.
• Aircraft integrators and maintenance - to assess installation practices (tie spacing, loop radii) that preserve impedance, attenuation and crosstalk performance.
• Test laboratories - to apply repeatable, standardized methods for acceptance testing and supplier verification.

Practical outcomes include consistent test records (initial, intermediate, final curves), documented comparison against product limits, and measurable criteria to support design or corrective actions when tie-induced deformation affects signal integrity.

Related Standards

• EN 3475-100 - General requirements for aerospace electrical cable test methods
• EN 3475-805 - Characteristic impedance (referenced for impedance checks)
• EN 3475-806 - Attenuation
• EN 3475-808 - Cross-talk
• EN 3475-812 - Return loss (VSWR)
• EN 4056-003 - Plastic cable ties product standard

By following EN 3475-513:2025, manufacturers and test labs can standardize deformation-resistance testing and demonstrate installed-cable reliability under typical aircraft harnessing conditions.
