Overview
EN 2349-316:2006 - "Aerospace series - Requirements and test procedures for relays and contactors - Part 316: Mechanical life (Endurance at reduced load)" specifies a standardized method to determine the mechanical service life (endurance at reduced load) of relays and contactors used in aerospace equipment. Published by CEN and prepared by ASD‑STAN, this European standard is intended to be used together with EN 2349-100 (general requirements) and referenced product standards.
Key topics and requirements
- Test purpose: Measure mechanical life (endurance at reduced load) of relay and contactor contacts under defined cycling conditions.
- Mounting and wiring: Units shall be mounted and wired in accordance with EN 2349-100 and the product’s rated contact load.
- Load and voltage:
- Each normally closed and normally open contact is loaded with 25% of the resistive load specified in the product standard.
- The open contact voltage must conform to the product standard.
- The coil shall be energized at the rated voltage during testing.
- Cycle profile:
- Connection time: (1.5 ± 1) s
- Disconnection time: (1.5 ± 1) s
- Number of cycles: specified by the applicable product standard (noted in EN 2349-316).
- Failure criteria and pass requirements:
- A voltage drop greater than 10% of the open contact voltage constitutes a failure.
- The sample must withstand the specified number of cycles without malfunction.
- No mechanical damage and no sticking or seizing of contacts are allowed.
- Additional checks: Pick-up and drop-out voltages are to be verified according to EN 2349-301.
Applications and users
This standard is directly applicable to companies and professionals involved in aerospace electrical component development, qualification, procurement and maintenance:
- Design and test engineers validating relay and contactor mechanical endurance.
- Qualification and certification bodies ensuring component compliance with aerospace test procedures.
- Manufacturers and suppliers of aerospace relays/contactors specifying endurance performance for product datasheets.
- Maintenance and reliability teams assessing service life and replacement intervals under reduced-load cycling.
Using EN 2349-316:2006 helps ensure consistent, repeatable mechanical life testing and supports product acceptance and airworthiness decisions for aerospace electrical systems.
