Overview
SIST EN 2349-318:2009 specifies standardized test methods for assessing the performance of aerospace relays and contactors under temperature extremes. Specifically, it details the procedures for measuring pick-up voltage at high temperature and drop-out (release) voltage at low temperature. This standard ensures reliability in electric switching components used in aerospace applications, supporting rigorous requirements for reliability and safety. Compliance with this standard is critical for organizations involved in the design, manufacturing, and quality assurance of aerospace electrical systems. SIST EN 2349-318:2009 must be applied together with the general requirements defined in EN 2349-100.
Key Topics
- Pick-up Voltage at High Temperature:
- Defines the conditions and methods for measuring the minimum voltage required for relay or contactor operation at elevated temperatures.
- Procedures include specific mounting, stabilization, and measurement requirements to ensure consistent and reproducible results.
- Drop-out Voltage at Low Temperature:
- Details how to evaluate the voltage at which an energized relay or contactor will open its contacts when subjected to low temperatures.
- Involves storage and measurement protocols at specified low temperatures and clear step-by-step test sequences.
- Test Criteria:
- Requires results to conform to product-specific voltage ranges.
- Mandates validation through additional referenced tests (EN 2349-201, EN 2349-301, EN 2349-303, EN 2349-307, EN 2349-412).
- Systematic Test Methods:
- Stresses the importance of using controlled environments such as heating and cooling cabinets.
- Standardizes timeframes for specimen stabilization before testing to eliminate variables.
Applications
- Aerospace Equipment Manufacturers:
- Ensures that relays and contactors will perform reliably despite extreme in-service temperatures encountered in flight or space vehicles.
- Supports effective qualification and production testing in quality assurance programs.
- Component Design and Evaluation:
- Provides clear methodologies for R&D teams to verify new electrical designs for environmental resilience.
- Maintenance and Compliance Verification:
- Used as a benchmark during maintenance, repair, and overhaul (MRO) to confirm that components still meet functional requirements.
- Safety and Certification:
- Essential for compliance with industry regulations and achieving airworthiness approvals for electrical components.
- Procurement and Supplier Assessment:
- Offers clear, harmonized requirements for specifying and sourcing aerospace-grade relays and contactors from suppliers.
