Overview
EN 2349-402:2006 is a CEN aerospace standard that defines a method to verify the ability of relays and contactors to resist corrosion caused by salt spray. Intended for use together with EN 2349-100 (general requirements), this part (Part 402) focuses specifically on salt-fog exposure and inspection criteria to ensure electrical switching devices meet aerospace corrosion resistance expectations.
Key topics and technical requirements
- Scope: Method for checking relays and contactors against corrosion from salt spray; used in conjunction with EN 2349-100.
- Mounting and wiring: Electrical connections must be wired per the applicable product standard before testing.
- Test method reference: Salt spray exposure is performed in accordance with ISO 7137:1995 (Aircraft - Environmental conditions and test procedures for airborne equipment). Note: ISO 7137 aligns with recognized airborne test publications (EUROCAE/ED‑14 and RTCA/DO‑160).
- Inspection: Post-test assessment follows EN 2349-201 (visual inspection). The device is checked for:
- No visible damage caused by the salt spray
- No corrosion affecting functional parts
- No signs of salt penetration into enclosures or critical interfaces
- Pass/fail criteria: Visual inspection must reveal no damage, corrosion, or salt ingress to meet the requirements of EN 2349-402.
Practical applications
- Qualification and acceptance testing of aerospace relays and contactors exposed to marine or saline operational environments.
- Environmental screening during component design and supplier validation to ensure corrosion resistance.
- Verification for maintenance, refurbishment, or life‑cycle assessments where salt exposure is a risk.
- Supporting procurement specifications and quality assurance checks for avionic and airborne electrical systems.
Who should use this standard
- Aerospace component manufacturers and suppliers of relays and contactors
- Test laboratories performing environmental and corrosion testing for avionics
- Design and reliability engineers validating component durability in saline atmospheres
- Quality assurance, procurement, and certification teams specifying acceptance criteria
