Overview
EN 2349-319:2006 - “Aerospace series - Requirements and test procedures for relays and contactors - Part 319: Miss test” is a CEN European standard that specifies a method to perform the relay miss test. Its purpose is to demonstrate conformance to the minimum current requirements for aerospace relays and contactors. This part is intended to be used together with EN 2349-100 (general requirements).
Key topics and requirements
- Scope: Defines a standardized procedure to verify that a relay/contact does not miss operations at low contact currents.
- Mounting method: Device under test shall be wired per EN 2349-100 and placed in a heating cabinet during the test.
- Test conditions:
- Contact load: 300 μA / 5 V d.c.
- Number of operations: 5 000
- Allowed number of misses: 0
- Alarm level during test: 100 Ω (dynamic contact resistance)
- Acceptance criterion: There shall be no missed operations during the specified sequence.
- Normative reference: EN 2349-100 is indispensable for applying this procedure.
Practical applications
- Verification of relay and contactor performance at minimal current levels for aerospace applications.
- Use in qualification testing, production acceptance, and reliability assessments where low-contact-current operation is critical.
- Employed by:
- Aerospace component manufacturers for design verification and production testing.
- Aerospace test laboratories to validate compliance with minimum current requirements.
- Quality assurance and procurement teams to establish supplier compliance.
- Certification and regulatory bodies reviewing component test evidence.
Why it matters (keywords)
EN 2349-319:2006 provides a repeatable miss test procedure to ensure aerospace relays and contactors reliably close and open under minimum current conditions. It helps prevent latent failures in avionics and power distribution systems where low drive currents and contact resistance can cause missed operations.
