Overview
EN 3745-503:2005 - “Aerospace series - Fibres and cables, optical, aircraft use - Test methods - Part 503: Scrape abrasion” is a CEN/AECMA test standard that specifies a repeatable method to evaluate the scrape abrasion resistance of optical fibres and optical cables used in aircraft. The standard defines the specimen preparation, required apparatus and the test procedure to determine the number of scrape cycles to sheath penetration while monitoring optical attenuation.
Key topics and technical requirements
- Scope: Measures resistance of an optical cable jacket to a scraping action until sheath penetration.
- Specimen preparation: Prepared as per EN 3745-100; typical specimen length is 0.75 ± 0.05 m. Test parameters (load, number of cycles, attenuation limits, inspection intervals) must be specified in the product/test plan.
- Apparatus:
- Light Launch System (LLS) and Light Detector System (LDS) as defined by EN 2591-100 for optical power/attenuation monitoring.
- Climatic chamber to run tests at ambient and at the cable’s maximum operating temperature.
- Scrape abrasion test fixture that wears the jacket parallel to the cable axis over a wear length of (10 ± 1) mm at a frequency of (55 ± 5) cycles/min (needle mechanism, mass, anvil and clamps as shown in the standard).
- Test method:
- One cycle = forward and backward movement of the needle.
- Resistance defined as the number of complete cycles before sheath penetration.
- Attenuation is continuously monitored in accordance with EN 3745-301 (method C).
- Procedure includes repeating the test five additional times, moving the cable 100 mm and rotating it 90° between each test (always in same rotation direction).
- Final inspection: Visual examination per EN 3745-201 and recording of damage and attenuation changes.
Applications and users
This standard is practical for:
- Aerospace cable manufacturers validating jacket formulations and assembly processes for aircraft optical cables.
- Qualification and test laboratories performing acceptance, qualification or comparative abrasion testing.
- Design and quality engineers specifying cable performance for harnesses, avionics and in-flight systems.
- Procurement and certification authorities requiring documented mechanical durability data for optical cable acceptance.
EN 3745-503:2005 helps ensure reliable optical performance under mechanical wear conditions typical of aircraft installations.
