Overview

EN 3745-511:2002 - "Aerospace series - Fibres and cables, optical, aircraft use - Test methods - Part 511: Cable to cable abrasion" - is a CEN-adopted aerospace test standard prepared by AECMA. It specifies a laboratory method to measure the abrasion resistance of optical cables when they rub against other cables (cable-to-cable abrasion). The standard is intended for use in the aviation/aerospace sector to verify durability and mechanical compatibility of optical cabling in aircraft installations.

Key Topics and Requirements

• Scope: Defines a test method to assess resistance of an optical cable (cable B) to abrasion from another cable (cable A).
• Specimen preparation: Specimens must be prepared per the applicable product standard and conditioned under standard test conditions for 24 hours as defined in EN 3745-100.
• Apparatus & setup:
  • Cable A is mounted on a moving jig that oscillates at 10 Hz with an amplitude of 6.35 ± 0.25 mm (peak to peak).
  • Cable B is secured on a fixed bracket and is wrapped so it turns once around cable A.
  • The cable friction point should be at the middle of cable A (±10%) and the contact angle (α) must be between 20° and 22°.
  • The pulley diameter used in the setup must be greater than 14 times the cable diameter.
  • A load (M) is applied to cable B to provide tension; the specimen length (L) must be adjusted to avoid resonances during testing.
• Procedure: Attach cables, apply the specified load, initiate friction (oscillation), and inspect cable B visually at the specified time intervals.
• Evaluation: Final assessment of damage is performed by visual examination in accordance with EN 3745-201.

Applications - Who Uses This Standard

• Aerospace and aircraft systems manufacturers validating optical fiber harnesses.
• Cable designers and suppliers qualifying cable construction for aircraft use.
• Test laboratories performing mechanical durability and qualification testing.
• Quality assurance, certification bodies, and maintenance engineers assessing in-service cable wear and routing compatibility. Practical use cases include verifying abrasion performance where optical cables run in bundles, through clamps, or adjacent to electrical cables and ensuring long-term reliability of avionics fiber-optic links.

• EN 3745-201: Visual examination procedure used to assess damage after testing.
• Other parts of the EN 3745 series cover additional test methods for aerospace optical cables.
