Overview

EN 2591-6401:2001 is a European aerospace standard developed by CEN in cooperation with the European Association of Aerospace Manufacturers (AECMA). It specifies a test method for evaluating the steady state acceleration resistance of optical elements used in aerospace electrical and optical connections. This standard is essential for ensuring that optical connection elements, including permanent connections and fibre optic couplers, can withstand continuous acceleration stresses typical in aerospace environments.

This standard is designed to be used alongside EN 2591-100, which covers general test methods for aerospace electrical and optical connections. Together, they provide a comprehensive framework for qualifying optical elements in critical aerospace applications.

Key Topics

• Scope and Purpose: Defines a testing method to assess the capability of optical elements to maintain performance under continuous acceleration.
• Test Specimens: Optical elements, permanent connections, and fibre optic couplers fitted with normal accessories and terminated with optical cable or fibre.
• Test Methodology:
  • Specimens are subjected to steady acceleration for a total of 30 minutes-5 minutes along each of the three tri-rectangular axes.
  • Acceleration levels are as specified in EN 2591-401, part of the overall aerospace test series.
  • Attenuation variations are continuously monitored throughout the test and must not exceed product-specific limits.
• Measurement Parameters:
  • Initial and final attenuation measurements as per EN 2591-602 and EN 2591-6101.
  • Additional assessments include optical discontinuity and mating/unmating forces per EN 2591-408.
• Compliance Requirements: Results must meet the acceptance criteria defined in the technical product standards aligned with aerospace quality and reliability needs.

Applications

EN 2591-6401:2001 is particularly vital in aerospace manufacturing and quality assurance testing where optical elements and fibre optic couplers are integrated into aircraft and spacecraft electrical systems. Its practical applications include:

• Aerospace Optical Connection Qualification: Certifying connectors and couplers for durable operation under dynamic acceleration conditions encountered during flight.
• Reliability Verification: Ensuring optical signal integrity and mechanical robustness to maintain communication and control systems functionality.
• Design Validation: Assisting designers in assessing component resilience and optimizing materials and structures against vibration and acceleration forces.
• Maintenance and Inspection: Establishing baseline performance parameters for optical elements to guide in-service evaluation and replacement schedules.

Related Standards

EN 2591-6401 must be used in conjunction with several other aerospace standards for electrical and optical connections to provide a comprehensive testing regime:

• EN 2591-100: General test methods for aerospace electrical and optical connection elements.
• EN 2591-401: Defines steady state acceleration parameters and procedures applicable to electrical and optical components.
• EN 2591-408: Test methods focused on mating and unmating forces for connection elements.
• EN 2591-602: Methods for assessing variation of attenuation and optical discontinuity in optical components.
• EN 2591-6101: Visual examination protocols for optical elements.

Collectively, these standards support consistent and rigorous evaluation of aerospace electrical and optical connectors ensuring safety, reliability, and performance in extreme operating conditions.
