Overview
EN 3475-301:2002 is a CEN (AECMA) aerospace test method standard that specifies how to measure ohmic resistance per unit length of electrical cables intended for aircraft use. It defines specimen preparation, measurement conditions and the temperature-correction practice required to report resistance values at the reference temperature of 20 °C. This part is intended to be used together with EN 3475-100 (general test method requirements).
Key topics and requirements
- Scope: Method for measuring electrical resistance per unit length of finished aerospace cables.
- Specimen preparation: Samples shall be taken from finished cable; minimum specimen length is 1 m.
- Measurement conditions:
- Conductor resistance must be stabilized to ambient temperature before measurement.
- A suitable bridge (precision resistance measuring instrument) is to be used for the measurement.
- Temperature correction:
- Measured resistance (R) must be corrected to the reference temperature of 20 °C.
- The standard provides temperature coefficients for correction:
- 0.004 per °C for common conductors,
- 0.0035 per °C for high-strength copper alloys.
- Acceptance requirement: The resistance value corrected to 20 °C shall be less than or equal to the resistance specified in the applicable product standard.
Applications and users
This standard is practical for organizations and roles involved in aerospace cable production, testing and procurement:
- Cable manufacturers - routine production testing and batch verification of conductor resistance.
- Test laboratories - compliance testing and certification of aircraft wiring.
- Aerospace OEMs and suppliers - incoming inspection, quality assurance and design verification.
- Maintenance and overhaul organizations - troubleshooting and verification of cable assemblies.
- Procurement and regulatory compliance teams - ensuring delivered cables meet specified electrical performance.
Practical uses include acceptance testing of new cable lots, verification of design or material changes (e.g., high-strength copper alloy conductors), and documentation of resistive properties for system electrical analysis.
