Overview
EN 2591-312:1997 - published by CEN - is an aerospace test-method standard titled Elements of electrical and optical connection - Test methods - Part 312: Air leakage. The standard defines a method for checking air leakage of seals at critical interfaces in electrical and optical connectors when subjected to an air pressure difference. It is to be used together with the general provisions of EN 2591 and applies to interfaces such as mounting panel/receptacle, housing (shell)/insulator, insulator/contacts, insulator/cables, and receptacle/plug.
Key topics and requirements
- Scope of testing: Focus on air-tightness of connector seals across defined interfaces under a specified air pressure difference.
- Test method: A standardized procedure for establishing test conditions, applying the pressure differential, and measuring leakage. (Note: specific test parameters and acceptance criteria are provided in the full standard and are used with EN 2591.)
- Specimen interfaces covered: Mounting panel and receptacle; housing (shell) and insulator; insulator and contacts; insulator and cables; receptacle and plug.
- Data and reporting: Requirements for recording leakage results and reporting test conditions to ensure repeatability and traceability.
- Integration requirement: Designed to be read and applied in conjunction with the other parts of EN 2591 for complete connector evaluation.
Applications
- Ensuring seal integrity of aerospace electrical and optical connectors used in pressurized compartments (e.g., avionics bays, cabin systems, environmental control interfaces).
- Supporting qualification and acceptance testing during connector design, production, and maintenance phases.
- Used by connector manufacturers, aerospace OEMs, test laboratories, and quality/approval authorities to verify compliance with pressure-differential leakage performance.
- Useful for risk mitigation where air leakage could affect system performance, safety, or environmental control in aircraft and spacecraft systems.
Who should use this standard
- Aerospace electrical and optical connector designers and engineers
- Manufacturing and quality assurance teams in connector production
- Independent test laboratories performing connector qualification tests
- Certification bodies and procurement authorities evaluating connector performance
