Overview - EN 3745-509:2002 (Kink test for aerospace optical cables)
EN 3745-509:2002 is a CEN / AECMA aerospace test method that specifies how to assess the resistance of optical fibres and cables to kinking for aircraft use. The standard defines specimen preparation, test sequence and pass/fail criteria for the kink test used in aerospace qualification, production verification and acceptance testing.
Key topics and technical requirements
- Scope: Method to test the resistance of an optical cable to kinking in aerospace applications.
- Specimen preparation
- Condition specimens at standard test conditions and stabilize for 24 hours as defined in EN 3745-100 (general test conditions).
- Use a specimen length of about 10 times the minimum bending radius of the cable.
- Unless otherwise specified, a loop minimum diameter value must be stated.
- Apparatus
- No specialized apparatus is prescribed in the standard; the test is performed manually as described.
- Test method
- Hold the specimen in both hands and form a loop in the original cable plane.
- Reduce the loop diameter to the specified minimum by pulling slowly on both ends; forces at the loop bottom must be applied in the same plane.
- If a kink in the cable jacket occurs during reduction, record the diameter at which it appears.
- Acceptance criterion
- No kink shall occur at a diameter equal to or greater than the specified loop minimum diameter.
Practical applications and who uses it
EN 3745-509:2002 is used by:
- Aerospace manufacturers and system integrators for qualification of optical cabling used in aircraft.
- Cable and harness suppliers to verify product performance to aerospace kink resistance requirements.
- Test laboratories performing mechanical qualification, production acceptance, and failure analysis.
- Certification and procurement teams specifying cable mechanical capability in technical specifications.
Typical uses:
- Design verification of optical cables and harnesses for aircraft routing paths with tight bends.
- Production quality control to ensure consistent kink resistance across batches.
- Supplier compliance checks during component acceptance and aircraft retrofit projects.
