Overview

EN 2591-701:2001 (Aerospace series) specifies a test method for the measurement of open circuit impedance of couplers used in aerospace electrical connection systems. Published by CEN and prepared by AECMA, this part (Part 701) addresses electrical elements and must be used together with EN 2591-100 (General test method provisions). The standard defines the test arrangement, signal conditions and acceptance criteria to verify that coupler impedance meets its technical specification.

Key topics and requirements

• Scope: Measurement method for open circuit impedance of couplers (electrical elements).
• Test setup: Coupler connected in a simple arrangement involving a bus, an impedance meter and a stub (as indicated in the standard’s figure). The specimen preparation details and any deviations must be stated in the technical specification.
• Test signal: Sinusoidal waveform, frequency range 75 kHz to 1 MHz, amplitude 1 V r.m.s.
• Parameters to declare: Impedance value to be verified, signal frequency and amplitude, and test temperature (unless otherwise defined in the technical specification).
• Requirement: Measured impedance shall comply with the value specified in the applicable technical specification for the coupler.
• Normative reference: To be applied together with EN 2591-100 which covers general test method rules for elements of electrical and optical connection.

Keywords: EN 2591-701:2001, open circuit impedance, couplers, impedance measurement, aerospace connectors, test methods.

Practical applications

• Verifying the open-circuit impedance of couplers during design qualification and production acceptance testing.
• Ensuring electrical compatibility and impedance matching of connector interfaces in aerospace harnesses and avionic systems.
• Supporting quality assurance, incoming inspection and maintenance procedures where impedance characteristics affect signal integrity or system performance.
• Providing a repeatable laboratory test method for test houses and OEM laboratories performing connector characterization.

Who uses this standard

• Aerospace manufacturers and integrators
• Connector and coupler designers
• Test laboratories and certification bodies
• Quality assurance and maintenance teams in avionics and aircraft systems
• Suppliers specifying electrical performance in technical specifications

Related standards

• EN 2591-100 – Aerospace series – Elements of electrical and optical connection – Test methods, Part 100: General (normative reference for Part 701).
• AECMA publications and CEN/CENELEC documents governing aerospace connector test methods and national implementations.

This standard is practical for anyone needing a standardized, reproducible procedure to measure and confirm the open-circuit impedance of electrical couplers in aerospace applications.
