Overview
EN 3475-807:2025, part of the Aerospace series, specifies methods for measuring the transfer impedance of electrical cables intended for aircraft use. The document is intended to be used together with EN 3475-100 (general test requirements) and IEC 62153-4-3 (triaxial surface transfer impedance methods). Its purpose is to provide a harmonized approach for evaluating cable coupling behaviour and supporting compliance with electromagnetic compatibility (EMC) requirements.
Key Topics
- Scope and intent: Defines the measurement objective - the transfer impedance Z of a cable - without prescribing product limit values (those are set in the relevant product standard).
- Specimen preparation: Tests require specimens to be stripped and prepared for connection to the chosen measuring device; correct preparation is essential for repeatable results.
- Test method reference: The triaxial test procedures of IEC 62153-4-3 are to be used. That standard describes several triaxial measurement methods; the exact method selected must be reported with the measured value.
- Reporting and requirements: Measured transfer impedance values shall be compared to the thresholds specified in the applicable product standard. The actual IEC method used must be documented alongside test results.
Applications
Measuring transfer impedance under EN 3475-807:2025 has practical value across aerospace cable development, qualification and procurement:
- EMC qualification: Assess how well cable shielding limits electromagnetic coupling into or out of conductors.
- Design verification: Support material and construction choices for shielded cables to meet aircraft EMC requirements.
- Production control: Verify consistent shielding performance across manufactured cable batches.
- Acceptance testing: Provide objective data for certification and supplier acceptance, where product standards reference transfer impedance limits.
Benefits include improved system reliability, reduced risk of interference with avionics, and clearer traceability of test methods and results.
Related Standards

- IEC 62153-4-3 - Metallic communication cable test methods: EMC - Surface transfer impedance - Triaxial method (provides the detailed triaxial procedures referenced by EN 3475-807).
Practical notes: Always report the exact IEC triaxial method used, specimen preparation details and test conditions when submitting transfer impedance results. Transfer impedance values are to be compared with limits defined in the specific cable product standard rather than in EN 3475-807 itself.
