Overview
EN 2349-411:2007 is a CEN aerospace standard that defines a method to verify the capability of relays and contactors to withstand temperature change. Intended to be used together with EN 2349-100 (general requirements), this part specifies the test procedure, duration and pass/fail criteria and cross-references related functional and inspection tests. The temperature-change test is carried out in accordance with ISO 7137 environmental conditions for airborne equipment.
Key topics and requirements
- Scope: Checks capability of relays and contactors to tolerate temperature variations without degradation.
- Mounting: Electrical connections must be wired in accordance with the applicable product standard prior to testing.
- Test method: Temperature change test performed per ISO 7137 environmental procedures.
- Duration: 48 hours total test duration.
- Post-test requirements:
- Visual inspection per EN 2349-201 - no signs of overheating or distortion.
- Functional and electrical verification per:
- EN 2349-301: Pick-up and drop-out voltage
- EN 2349-303: Dielectric strength
- EN 2349-304: Operate and release time
- EN 2349-305: Bounce time
- EN 2349-307: Contact voltage drop
- Pass/fail criteria: No overheating or physical distortion; compliance with the specified electrical and functional performance tests listed above.
Practical applications
- Component qualification and environmental screening of aerospace relays and contactors before installation in aircraft and airborne systems.
- Supplier and procurement specification: used by OEMs and Tier‑1 suppliers to require validated temperature-change resilience from vendors.
- Test laboratories and QA teams use EN 2349-411 to structure environmental testing programs and to demonstrate conformity during product approval and audits.
- Design verification for engineers developing relay/contactors intended for aerospace service to ensure reliable operation across expected temperature cycles.
Who should use this standard
- Aerospace electrical and systems engineers
- Component manufacturers of relays and contactors
- Environmental test laboratories and certification bodies
- Procurement, quality assurance and compliance teams in aviation and defense industries
