Overview

EN 3373-010:2009 is a CEN product standard in the Aerospace series that specifies the characteristics of tin‑plated copper, ring‑shaped terminal lugs intended for crimping onto copper conductors. The standard covers terminals for both metric and inch stud series and limits continuous operating temperature to up to 150 °C. It is intended to be used in conjunction with EN 3373-001 (technical specification and quality requirements).

Key topics and requirements

  • Scope and materials
    • Ring shaped terminal lugs made of copper with tin plating for crimping on copper conductors.
    • Operational temperature range: −65 °C to 150 °C.
  • Design and workmanship
    • Split‑barrel constructions must be permanently sealed and must not open during crimping.
    • All surfaces must be smooth and free from burrs and sharp edges.
  • Dimensions and identification
    • Detailed dimensions and mass are specified (Table 1 / Figure 1) and are based on metric conversions of SAE‑AS 20659. Items are identified by code numbers (see Table 1).
    • Provision for inspection hole(s) and a defined marking area.
  • Testing and performance
    • Applicable test methods referenced from EN 2591 series include visual inspection, dimensional checks, voltage‑drop measurement, ageing by temperature/current cycling (1 500 cycles to 150 °C), endurance at temperature (120 h at 165 °C), rapid temperature change, salt mist, vibration, and tensile strength of crimped connections.
    • Quality assurance is to follow EN 3373‑001.
  • Assembly tooling
    • Crimping tools must conform to MIL‑DTL‑22520. For conductor sizes up to 050 use tool M22520/5‑01; for 090 and larger use tooling conforming to MS25441. Die dimensions reference MS90485 where applicable.
  • Marking and packaging
    • Marking: item code and manufacturer monogram embossed per EN 2424 Style F.
    • Packaging must include EN designation, manufacturer name, part number, quantity, manufacture date and batch number.

Applications

  • Use in aerospace electrical systems: wiring harnesses, power distribution, avionics and grounding connections where high reliability and controlled crimp performance are required.
  • Relevant to manufacturers of aerospace terminals, electrical harness suppliers, procurement/specification engineers, quality assurance teams, and test laboratories.
