Overview

EN 3373-002:2009 is Part 002 of the CEN “Aerospace series - Terminal lugs and in-line splices for crimping on electric conductors.” Rather than defining performance test methods, this part provides the general framework and a consolidated list of all EN 3373 product standards required for the production and specification of crimp connections used in aerospace electrical systems. It is a reference index that directs users to the applicable product-specific standards and to the technical and quality assurance documents needed to implement compliant crimped connections.

Key topics and requirements

  • Scope: Lists all parts of EN 3373 required for producing crimp connections.
  • Normative references: Identifies indispensable documents for application - notably EN 3373-001 (technical specification) and EN 9133 (quality management / qualification procedure for aerospace standard parts).
  • List of product standards: Consolidates product-specific parts (EN 3373-007 to EN 3373-014), including:
    • Nickel-plated aluminium terminal lugs for nickel-plated aluminium cable (inch studs)
    • Copper lugs, nickel-plated ring-shaped (up to 340 °C, inch studs)
    • Insulated ring-shaped copper terminal lugs (up to 260 °C, metric and inch)
    • Tin-plated ring-shaped copper terminal lugs (up to 150 °C)
    • Nickel-plated ring-shaped copper terminal lugs (up to 260 °C)
    • In-line splices - insulated/sealed and moisture resistant variants (temperatures up to 150 °C, 200 °C and 260 °C)
  • Quality assurance reference: Points to EN 9133 for qualification and quality system requirements for aerospace standard parts.
  • Technical specification reference: Directs users to EN 3373-001 for the detailed technical requirements and test methods for crimp connections.

Applications

  • Specifying and procuring terminal lugs and in-line splices for aircraft wiring harnesses and other aerospace electrical installations.
  • Creating product documentation and part catalogs that must reference the correct EN 3373 product standard for material, temperature rating, and stud series (metric or inch).
  • Guiding manufacturers and suppliers in selecting the correct crimp product standard for high-temperature, moisture-resistant, or plated conductor applications.

Who should use this standard

  • Aerospace electrical engineers and harness designers
  • Component manufacturers and suppliers of crimp terminals and splices
  • Procurement specialists writing technical specifications and purchase orders
  • Quality managers and certification bodies applying EN 9133 qualification procedures

Related standards

  • EN 3373-001: Technical specification for crimped terminal lugs and splices
  • EN 3373-007 to EN 3373-014: Product standards listed in EN 3373-002 (material, plating, temperature and design variants)
  • EN 9133: Quality management / qualification procedure for aerospace standard parts
