Overview
EN 3373-008:2012 is a CEN aerospace product standard that specifies nickel-plated copper ring terminal lugs for crimping onto nickel-plated copper conductors (as defined in EN 2083). These ring-shaped lugs are designed for use on inch-series studs and for continuous operation at temperatures up to 340 °C. The standard is intended to be used in conjunction with EN 3373-001 (technical specification for terminal lugs and in-line splices).
Key topics and requirements
- Material and plating
- Copper conductor material per ASTM B152.
- Surface protection: nickel plating in accordance with SAE AMS-QQ-N-290B.
- Temperature range
- Operational range specified from −65 °C to 340 °C.
- Dimensions and mass
- Mandatory dimensions and mass are provided (metric, millimetres); other non-mandatory dimensions left to manufacturer discretion.
- Typical AWG sizes referenced (examples in the standard include AWG 8 up to AWG 000 and corresponding inch stud diameters).
- Crimping and tool requirements
- Tools must produce the specified compression percentage and crimp profile to meet EN 3373-001 joint requirements.
- Tooling guidance references MIL‑DTL‑22520G and requires punch/die sets from the same manufacturer; dies should be engraved with AWG gauge numbers.
- Marking and packaging
- Marking per EN 2424 (manufacturer monogram and AWG code embossed).
- Packaging must show EN designation, manufacturer name, part number, quantity, manufacture date and batch number.
- Quality assurance
- Inspection and QA provisions referenced to EN 3373-001.
Applications
- Designed for aerospace electrical harnesses where high-temperature resistance and reliable stud-mounted connections are required.
- Typical use cases:
- Engine and auxiliary power unit (APU) compartments
- Hot zones in airframe and propulsion systems
- Any avionics or electrical system requiring nickel-plated copper conductors and inch-series stud terminations
- Primary users:
- Aerospace OEMs and suppliers, electrical harness manufacturers, quality/standards engineers, tooling and crimp-die manufacturers, and MRO/repair facilities.
