Overview
SIST EN 2591-6314:2004 is a key European aerospace standard focused on the testing of optical elements within electrical and optical connections used in aerospace systems. Specifically, it defines the immersion test method at low air pressure to assess the sealing integrity of optical connection elements and fibre optic couplers when exposed to low-pressure environments. This standard ensures that optical components maintain reliable performance in aerospace applications where pressure variations are common.
Developed by the European Association of Aerospace Manufacturers (AECMA) and published under the CEN framework, EN 2591-6314 complements other related aerospace connection standards, providing critical procedures for quality assurance in harsh operational contexts.
Key Topics
Scope of testing
EN 2591-6314 specifies the method to check the sealing of optical connection elements, including permanent and temporary connections as well as fibre optic couplers, exposed to low air pressure. The test is designed to ensure no ingress or damage occurs under these conditions.Preparation of specimens
Optical elements must be prepared with normal accessories, terminated per product standards, and properly fitted with protective covers or filler plugs where necessary. Testing applies to both mated and unmated elements.Testing apparatus and pressure conditions
The low-pressure immersion test is conducted using apparatus detailed in EN 2591-314 (Part 314: Immersion at low air pressure), ensuring consistent and controlled vacuum conditions that mimic aerospace operating environments.Measurement procedures
- Initial measurements include baseline insertion loss following EN 2591-601.
- Immersion testing follows the low-pressure protocol from EN 2591-314.
- Final measurements assess insertion loss after three test cycles and a visual examination focusing on seal integrity and optical surface condition per EN 2591-6101.
Standards integration
EN 2591-6314 must be used in conjunction with EN 2591-100 (General test methods for electrical and optical connections), reinforcing an integrated approach to test planning and execution.
Applications
This standard is vital for aerospace manufacturers, designers, and testing laboratories engaged in the qualification and quality control of optical components used in:
Aerospace electrical and optical connection systems
Ensuring robust, reliable optical links in aircraft, spacecraft, and satellite communication systems.Fibre optic cabling in aerospace environments
Validating that fibre optic couplers and connectors withstand low-pressure conditions without seal failure or optical degradation.Component certification and aerospace system qualification
Supporting compliance with aerospace industry requirements for environmental and performance testing of critical connection elements.Research and development of optical connection technologies
Providing a benchmark test method for innovation in sealing solutions and optical fiber connectivity exposed to pressure variation.
