Overview
EN 3373-011:2009 is a CEN product standard in the Aerospace series that defines the characteristics of nickel-plated copper ring-shaped terminal lugs intended for crimping on nickel-plated copper conductors. These components are specified for use with both metric and inch stud series and are rated for service temperatures up to 260 °C (operational range −65 °C to 260 °C). This Part 011 standard is intended to be used in conjunction with EN 3373-001 (technical specification) and forms part of the wider EN 3373 series covering crimp terminals and splices.
Key Topics
- Material & finish: Nickel-plated copper ring-shaped terminals for crimping on nickel-plated copper conductors.
- Temperature rating: Operational and test exposure up to 260 °C maximum; design range covers −65 °C to 260 °C.
- Construction: When split-barrel designs are used, the split must be permanently sealed so it does not open during or after crimping. All surfaces must be smooth and free from burrs.
- Dimensions & designation: Detailed dimensions and mass values are given (see Table 1 and Figure 1 of the standard). Item codes align with table entries and the EN 3373-011 designation format.
- Quality & testing: Quality assurance follows EN 3373-001. Applicable test methods from EN 2591 series include visual examination, dimensional checks, voltage drop, ageing by temperature/current cycling (1 500 cycles to 260 °C), endurance at temperature (120 h at 275 °C), rapid temperature change, salt mist, vibration, and tensile strength of crimped connections.
- Assembly tooling: Crimp tooling requirements reference MIL-DTL-22520. For conductors up to size 050, use tools equivalent to M22520/5-01; for sizes 090 and above, use tools conforming to MS 25441. Die dimensions for larger sizes reference MS 90485.
- Marking & packaging: Marking includes the item code and manufacturer monogram (embossed per EN 2424 Style F). Packaging must be labelled with EN designation, manufacturer name, part number, quantity, manufacture date and batch number.
Applications
- Aerospace electrical harnesses and power distribution where high-temperature resistance is required.
- Circuits using nickel-plated copper conductors and installations requiring compatibility with both metric and inch threaded stud terminals.
- Environments where defined mechanical, electrical and environmental test performance (vibration, salt mist, thermal cycling) is mandatory.
