Overview

EN 2241:2010 - "Aerospace series - Lamp caps - Dimensions" is a CEN European standard that defines the dimensional requirements for caps used on incandescent lamps installed on board aircraft. The document establishes geometric sizes, tolerances (in millimetres), and reference drawings for a broad range of lamp cap types used in aerospace electrical systems. It links cap dimensions to the lamp characteristics and test methods defined in EN 2240-001 and EN 2756.

Key topics and technical requirements

  • Scope and intent: Specifies cap geometry to ensure interchangeability and correct mechanical/electrical fit in aircraft lampholders.
  • Dimensions & tolerances: Detailed figures and tables give minimum and maximum dimensions (millimetres) for multiple cap families, including:
    • Bi‑pin types (various pin diameters and spacings)
    • Single‑end and bayonet types: SX4s/4, SY4s/7, SX6s, S5,7s/8
    • Bayonet and automotive-derived bases: BA7s/12, BA9s/13, BA15s/19, BA15d/19, BAY15s/19, BA15s3/19, BA20d
  • Reference conformity: Several cap types are explicitly stated to be in conformity with EN 60061‑1:1993 sheets where applicable.
  • Measurement practices: Figures include datum lines, chamfers, bulb-edge details and notes on non‑assembled base measurements; pin location and relative position checks are referenced (gauge under study).
  • Quality & technical control: Quality assurance follows EN 9133 procedures; technical lamp specifications and test methods are covered by EN 2240‑001 and EN 2756 respectively.

Practical applications

  • Ensures mechanical and electrical interchangeability of incandescent lamp caps across aerospace suppliers and maintenance providers.
  • Used by:
    • Aerospace component manufacturers (lamp and cap production, tooling and inspection)
    • Aircraft OEMs and systems integrators (specifying correct lamp cap types for lighting and indicator systems)
    • Maintenance, repair & overhaul (MRO) organizations and avionics workshops (replacement and compatibility checks)
    • Test laboratories and quality auditors (dimensional inspection, conformity assessment)
  • Supports procurement specifications, design verification, and regulatory compliance for aircraft electrical lighting systems.
