Overview

EN 3475-501:2006 is a European standard specifying a dynamic cut-through test method for electrical cables used in aerospace applications. It measures the resistance of insulated conductors or cable jackets to mechanical cut-through forces. This standard applies specifically to cables smaller than code 140 (gauge size 6) with insulation thicknesses of 0.38 mm or less.

Developed under the European Association of Aerospace Manufacturers (AECMA) and adopted by CEN, EN 3475-501:2006 ensures consistent, reliable testing of cable durability under conditions simulating potential mechanical damage in aircraft environments. It must be used together with EN 3475-100, which covers general test methods for aerospace cables.

Key Topics

• Scope: Defines the test for cables with small gauge sizes and thin insulation, critical for assessing resistance to damage in high-vibration and harsh aerospace conditions.
• Specimen Preparation: Test samples consist of 450 mm insulated cable lengths with one end prepared for electrical connection.
• Test Apparatus:
  • Tensile tester operating in compression mode with a sharp cutting edge positioned perpendicular to the cable axis.
  • Heating chamber to stabilize test temperature as required by the product standard.
  • Low voltage detection circuit to stop the test upon cut-through detection.
• Test Method:
  • Conduct tests at specific temperatures dictated by the cable product standard, allowing up to one hour for temperature stabilization.
  • Apply a constant loading rate of 1 ± 0.1 N/s.
  • Move the cutting edge through insulation while the specimen is moved longitudinally and rotated systematically for multiple measurements.
  • Perform eight tests per specimen.
• Test Requirements: The arithmetic mean of the eight cut-through forces must exceed the minimum values specified in the applicable product standard, ensuring cable integrity and safety.

Applications

EN 3475-501:2006 is essential for aerospace manufacturers, suppliers, and testing laboratories working with aircraft electrical wiring to:

• Validate mechanical durability of insulated cables used in aircraft electrical systems.
• Ensure compliance with aerospace quality specifications and regulatory requirements.
• Prevent in-service failures caused by abrasion, pinching, or cutting forces experienced during aircraft operation and maintenance.
• Support aerospace system design by providing data on cable resistance to mechanical damage.
• Improve safety and reliability of electrical installations in commercial, military, and space vehicles.

Related Standards

• EN 3475-100: Aerospace series cables - General test methods - Part 100. This standard provides foundational test methods to accompany EN 3475-501 for comprehensive cable evaluation.
• Other EN 3475 series parts focus on specific electrical and environmental cable tests, ensuring that aerospace cables meet rigorous performance and safety criteria.
• International aerospace standards developed by SAE and IEC complement this standard, creating a global framework for cable testing and certification.
