Overview
EN 2591-6303:2001 is a CEN/AECMA aerospace standard that defines test methods for optical connection elements under cold/low pressure and damp heat conditions. The standard verifies the long-term stability of optical elements, including permanent connections and fibre optic couplers, and is intended to be used together with EN 2591-100 (general test requirements). It specifies climatic preconditioning, measurement procedures and final acceptance checks relevant to aerospace electrical and optical connection systems.
Key topics and requirements
- Scope: Methods to assess long-term stability of optical elements when exposed to cold, low atmospheric pressure and damp heat environments typical of aerospace applications.
- Specimen preparation: Specimens must be fitted with normal accessories, terminated per product standard, and cavities with unterminated contacts fitted with filler plugs. Required details include cable/fibre type and length, maximum insertion loss, and permissible attenuation variation.
- Apparatus: Tests use one or two climatic chambers depending on the selected method (single-chamber Method A or two-chamber Method B).
- Test procedures:
- Climatic preconditioning per EN 2591-303.
- Initial optical measurements using EN 2591-601 (insertion loss) and EN 2591-602 (variation of attenuation/optical discontinuity).
- Continuous monitoring of attenuation variation (EN 2591-602, Method A) during the climatic cycle.
- Final measurements and acceptance:
- Visual examination (EN 2591-6101).
- Insertion loss verification (EN 2591-601).
- Integration requirement: Must be used in conjunction with EN 2591-100 (general test methods) and references EN 2591-303, EN 2591-601, EN 2591-602, EN 2591-6101 for related procedures.
Applications and who uses it
This standard is essential for:
- Aerospace manufacturers and suppliers who design, qualify or procure optical connectors and fibre optic couplers for aircraft and spacecraft.
- Environmental and reliability test laboratories performing climatic and humidity qualification testing.
- Quality assurance and certification teams validating long-term optical performance under extreme conditions (cold, low pressure, damp heat).
- Systems engineers integrating fibre-optic links in avionics, flight control, sensor and communication systems where long-term attenuation stability and low insertion loss are critical.
