Overview
EN 2346-003:2006 is a CEN aerospace product standard that defines fire resistant electrical cables (DL family, single core) for aircraft on-board electrical systems. It covers cables designed to operate in extreme environments with temperatures between −65 °C and 260 °C, specifying materials, construction, required characteristics, test methods and quality assurance requirements for the DL single-core family.
Key topics and technical requirements
- Scope and application
- Fire resistant electrical cable for aircraft use, single core (DL family), operating −65 °C to 260 °C.
- Materials and construction
- Conductors: nickel-clad copper alloy for 0.4 mm2 (code 004); nickel-clad copper for ≥ 0.6 mm2 (codes ≥ 006). Copper meets IEC 28; alloys per EN 2234.
- Insulation: electrical insulation specified to comply with EN 2234.
- Construction rules, core colour coding and number of cores referenced to EN 2346-002.
- Dimensional and electrical limits
- Nominal cross-sections, strand counts, conductor diameters, resistance at 20 °C, external diameters and mass per metre are tabulated in the standard (Table 1).
- Required characteristics and testing
- Comprehensive test program referenced to EN 3475-100 and EN 2234, including: visual, mass, dimensions, ohmic resistance, voltage proof (immersion/dry spark), insulation resistance, surface resistance, overload resistance (where applicable), accelerated ageing, thermal endurance (notably up to 40 000 h at 260 °C), thermal shock, flammability, fire resistance, dynamic cut‑through, scrape abrasion, torsion, tensile and plating tests, strippability and permanence of marking.
- Specific test parameters (temperatures, loads, acceptance limits) are provided in Tables 2 and 3 of the standard.
- Quality and identification
- Quality assurance per EN 9133; designation, marking, packaging and delivery lengths referenced to EN 2346-002 and EN 2234.
Applications and who uses it
- Intended for aerospace electrical cable designers, harness manufacturers, procurement specialists, certification and quality engineers, maintenance organizations and regulatory bodies involved in aircraft electrical systems.
- Typical applications: on-board wiring for power and signal circuits where fire resistance and wide operating temperature range are critical (e.g., avionics, power distribution, emergency circuits).
