Overview
EN 2349-407:2006 - Aerospace series - specifies a standardized method to verify the ability of relays (with plug-socket holders only) to withstand environmental stress from cold, low air pressure and moist heat. Intended as a part-specific test protocol, it is designed to be used together with EN 2349-100 (general requirements for relays and contactors). EN 2349-407:2006 references EN 2591-303 for test procedures and EN 2349-302 for post-test requirements.
Key topics and requirements
- Scope: Applies only to relays mounted in plug-socket holders used in aerospace electrical systems; it evaluates environmental robustness under low temperature, reduced pressure and humid heat conditions.
- Mounting: The plug-socket holder and relay must be wired in accordance with the applicable product standard prior to testing.
- Test procedure: The environmental exposure and sequence are performed in accordance with EN 2591-303 (Cold/low pressure and damp heat test methods). EN 2349-407 does not duplicate those test mechanics but mandates their use.
- Acceptance criteria: Post-test requirements and performance verification are carried out in accordance with EN 2349-302 (insulation resistance) and the general rules of EN 2349-100.
- Normative references: The standard relies on EN 2349-100 (general), EN 2349-302 (insulation resistance) and EN 2591-303 (environmental test methods).
Applications and who should use it
- Aerospace component manufacturers - to qualify relays and contactors for environmental exposure in aircraft and related platforms.
- Qualification and test laboratories - to perform standardized cold, low-pressure and moist-heat tests and report results consistent with aerospace requirements.
- Design and quality engineers - to ensure relay selection and design meet environmental durability expectations.
- Procurement and certification teams - to specify test requirements in contracts, supplier requirements and certification evidence.
- Maintenance and reliability engineers - to assess component suitability for operation in extreme environmental profiles.
