BS EN 2267-011:2023

Introduction

Analysis of the core content of the standard

BS EN 2267-011:2023 specifies the technical requirements for DZA series cables suitable for non-pressurized areas of aircraft. The main features include:

• Operating temperature range: -65°C to 260°C
• Voltage level: 115VAC (phase-to-neutral)/200VAC (phase-to-phase) or 230VAC/400VAC
• Arc resistance verification (damage ≤70mm under 230VAC conditions)

Material and structural requirements

Components	Technical requirements	Reference standards
Conductor	Copper or copper alloy + nickel plating (Type D), in line with EN 4434:2005 tight tolerances	4.1.1
Insulation layer	Foaming material is prohibited, minimum bending radius without wrinkles (EN 3475-405)	4.1.2
Lightweight version	Code "L", outer diameter/weight reduced by 5-12% (see Table 1)	4.2

Key performance test requirements

Electrical performance

• Partial discharge inception voltage (PDIV): ≥566V RMS @145mbar/150°C
• Hipple test: Dry pulse 4.0kV RMS
• Insulation resistance: In accordance with EN 3475-303

Mechanical properties

• Dynamic cutting force: 9mm² cable must be ≥135N at 260°C
• Low temperature bending: -65°C passed the test
• Scratch test: 1.2mm² cable 10N needle pressure resistance

Standard evolution analysis

Main changes compared to the 2015 version:

1. New lightweight versions (L12/L30/L51/L90)
2. Expanded AWG specifications to 8/10/12/16
3. Updated arc resistance test method (EN 3475-604/605)

Implementation recommendations

Design selection

Lightweight versions are preferred for non-pressurized areas. Note: L series must be clearly marked in the logo

Quality control

• Bend test + visual inspection (3x magnification, no wrinkles) is required for each batch
• Regular verification of coating continuity (EN 3475-506)
• Dry arc propagation test must be performed on 230VAC systems

Installation specifications

Refer to EN 2084:2018 minimum bending radius requirements to avoid mechanical damage to the insulation layer
