Overview

The prEN 3475-806:2023 standard is part of the aerospace series focused on electrical cables for aircraft use. It specifies test methods for measuring the attenuation of electrical cables used in aerospace applications. Attenuation refers to the reduction in signal strength as it travels through a cable, a critical parameter to ensure reliable signal transmission in aviation environments. Developed under the auspices of CEN and ASD-STAN, this standard updates and replaces the previous EN 3475-806:2002 edition, incorporating references to EN 50289-1 and maintaining alignment with EN 3475-100.

Key Topics

  • Test Methods for Attenuation
    The standard outlines two primary approaches for attenuation measurement:

    • The Insertion Method uses a harmonic mode transmission with calibrated attenuators to measure signal loss through the cable specimen, requiring a minimum attenuation of 3 dB.
    • The Voltage or Power Comparison Method calculates attenuation by comparing input and output voltage or power, using network analyzers or powermeters, applicable to both coaxial and balanced cables.

  • Specimen Preparation
    Cables must be fitted with appropriate connectors or stripped conductors for testing. For balanced cables, the use of baluns ensures impedance matching with unbalanced test equipment.

  • Test Setups and Equipment
    Detailed diagrams describe configurations involving signal generators, fixed and variable attenuators, measuring receivers, network analyzers, and terminating loads to ensure accurate and repeatable attenuation measurements.

  • Temperature Compensation
    Attenuation values are expressed in decibels per meter at 20°C, with a correction factor applied to account for temperature differences during testing.

  • Compliance Requirements
    Attenuation values must not exceed those specified in corresponding product standards, ensuring cable performance meets aerospace industry requirements.

Applications

This standard is essential for aerospace manufacturers, cable designers, and test laboratories aiming to certify electrical cables for aircraft systems. It ensures:

  • Signal Integrity in Aircraft Systems: Reduced attenuation means maintained signal quality for control, communication, and instrumentation cables critical to safe aircraft operation.
  • Quality Assurance: Uniform, repeatable test methods support compliance verification and quality control across international aerospace supply chains.
  • Product Development: Designers can use attenuation data to select suitable cable types based on performance at various frequencies and environmental conditions.
  • Certification and Regulatory Compliance: Meeting prEN 3475-806 requirements aids compliance with broader aviation standards and regulatory mandates.
