EN 2234:2018
(Main)Aerospace series - Cable, electrical, fire resistant - Technical specification
General Information
- Abstract
This document specifies the required characteristics and test procedures for fire resistant or fire-proof electrical cables for use in aircraft electrical systems. These cables should also maintain a specific surface resistance when they are subjected to a flame of 1 100 °C after 5 minutes (fire resistant) or 15 minutes (fire-proof) exposure.
The insulation of these cables is designed to withstand aircraft voltages at a frequency not exceeding 2 000 Hz. Unless specified by individual product standards the maximum demonstrated ac voltage of rating of these cables is 115 V rms (phase to neutral) and 200 V rms (phase to phase) and a long term temperature of up to 260 °C (ambient temperature plus temperature rise in conductor).

Overview
EN 2234:2018 - "Aerospace series - Cable, electrical, fire resistant - Technical specification" - is a CEN standard that defines required characteristics, construction and test procedures for fire resistant / fire‑proof electrical cables intended for aircraft electrical systems. It requires cables to withstand a 1 100 °C flame for specified durations (5 minutes for fire resistant, 15 minutes for fire‑proof) while maintaining surface resistance and electrical integrity. Insulation is specified for aircraft voltage environments up to 2 000 Hz, with typical maximum demonstrated AC ratings of 115 V rms (phase-to-neutral) and 200 V rms (phase-to-phase) and long‑term temperatures to 260 °C (ambient + conductor rise).
Key topics
- Scope & performance: Flame exposure criteria (1 100 °C), electrical rating limits, and long‑term temperature capability.
- Materials & construction:
- Conductors: nickel‑clad copper alloy for 0.25 mm² and 0.4 mm²; nickel‑clad copper for ≥0.6 mm². Nickel content ≥27 % by mass.
- Mechanical rules: allowed strand joints, lay lengths, compaction limits, sheath and insulation fit and strippability.
- Electrical and environmental requirements:
- Voltage proof, insulation resistance, surface resistance, arc tracking, wet/dry arc propagation.
- Thermal endurance, accelerated ageing, thermal shock, and resistance to fluids.
- Fire and safety tests:
- Flammability, fire resistance, smoke density and toxicity testing.
- Mechanical tests:
- Tensile, bend/cold bend, abrasion, torsion, flexure endurance and continuity/plating tests.
- Quality assurance & testing regime:
- Qualification, first article inspection, production routine tests, periodic re‑qualification (typically every three years).
- Identification & delivery:
- Marking per ISO 2574, packaging, labelling requirements and standard delivery lengths.
Applications
EN 2234:2018 is used by:
- Aerospace cable designers and manufacturers developing fire resistant aircraft wiring.
- Aircraft OEMs and MRO organizations specifying and procuring electrical cables for cockpits, avionics bays, engines and other systems where fire performance is critical.
- Certification and safety engineers validating cable performance against prescribed fire, smoke, toxicity and electrical tests.
- Suppliers preparing qualification evidence, first‑article inspection records and production test data.
Keywords: EN 2234:2018, fire resistant electrical cable, aerospace cables, aircraft electrical systems, cable testing, fire‑proof cable, aerospace standard.
