Overview

EN 4612-012:2019 is a CEN (European) product standard in the Aerospace series that specifies UV laser printable jacketed, nickel‑plated copper conductor electrical cables of the XLETFE family. It covers single‑ and multi‑core (1–4 cores) screened and jacketed cables with a dual‑extruded XLETFE jacket and woven nickel‑plated copper braid for use in aircraft on‑board electrical systems at operating temperatures between −65 °C and 150 °C and voltages up to 600 V rms. The insulation system is suitable for common aerospace supplies such as 115 V (phase‑to‑neutral) 400 Hz AC and 28 V DC.

Key topics and technical requirements

• Materials & construction
  • Cores per EN 4611‑007; 1 to 4 cores (2–4 cores twisted per EN 2235); no filler cores.
  • Nickel‑plated copper stranded woven screen (braid); material per EN 2083.
  • Outer jacket: crosslinked ethylene tetrafluoroethylene co‑polymer (XLETFE) and UV laser printable.
• Mechanical & electrical characteristics
  • Screen coverage: ≥ 85% (Annex A calculations).
  • Lay factor: < 3.
  • Insulation resistance: ≥ 500 MΩ·km at 20 ±2 °C, ≥ 1 MΩ·km at 95 ±2 °C.
  • Ohmic resistance, dimensions, mass – defined by size codes (see Table 1).
• Performance & environmental tests
  • Tests referenced from the EN 3475 series: visual, mass, dimensions, voltage proof, ageing (200 °C), shrinkage/delamination (150 °C), thermal shock (−65 °C/150 °C), bending, cold bend, flammability (Methods 1 & 2; 15 s flame, ≤3 s extinguish), scrape abrasion, dynamic cut‑through, plating continuity/adherence.
  • Smoke density and toxicity requirements for certain sizes (e.g., code 006 single core).
• Marking & traceability
  • UV laser markability with contrast K ≥ 50%; permanence and identification per EN 4612‑002.
• Quality
  • Quality assurance per EN 9133.

Applications and users

• Intended for airframe wiring without additional protection in aircraft electrical systems within the specified temperature and voltage limits.
• Typical users:
  • Aerospace cable manufacturers (product design & certification)
  • Aircraft OEMs and system designers (wire selection and installation)
  • Procurement, quality assurance and maintenance teams (specification, acceptance testing, replacement)
• Practical uses: wire harnesses, interconnection of avionics and power distribution where UV laser marking, braid screening, and wide temperature performance are required.

Related standards

• EN 4612‑002 (general XLETFE jacketed/screened requirements)
• EN 4611‑007 (core construction - nickel plated copper)
• EN 2235 (single/multicore screened & jacketed technical specification)
• EN 3475 (cable test methods)
• EN 2083 (conductors)
