Overview

EN 2240-011:2010 is a CEN European Standard that specifies the required characteristics for Lamp, code 85 intended for aerospace applications. The standard is part of the Aerospace series for incandescent lamps and is intended to be used together with EN 2756. It defines essential parameters required for consistent production, procurement and verification of incandescent lamps in aerospace electrical equipment and systems.

Key Topics

• Nominal ratings: The standard lists nominal electrical values (e.g., nominal voltage 12 V, nominal current 0.08 A, nominal power 0.96 W) and luminous output expectations.
• Optical and thermal data: Includes nominal luminous flux (4 lm) and a colour temperature value (approx. 2 170 K) as reference for visual performance.
• Life and endurance: Specifies life expectations under different operating modes (static with d.c., dynamic with d.c., static with a.c.), providing guidance for reliability and maintenance planning.
• Mechanical dimensions and mass: Defines dimensions (millimetres) and Light Centre Length (LCL = 8 ± 1 mm), plus mass data for batch handling (mass for 1 000 units = 0.4 kg) to support installation and logistics.
• Filament and cap: Declares filament form (C - 2F) and cap type SY4s/7 in accordance with EN 2241 and calls out cross-reference to EN 2240-002 for code designation rules.
• Marking and designation: Sets marking and designation rules so lamps and packaging are clearly identifiable for traceability and compliance.

Applications

EN 2240-011:2010 is intended to support practical needs across the aerospace supply chain, including:

• Component specification and procurement: Provides a consistent product description and electrical/mechanical data for purchasing and quality control.
• Manufacturing and acceptance testing: Used with EN 2756 (tests) and EN 2240-001 (technical specification) to verify conformity during production and incoming inspection.
• Maintenance and logistics: Life and marking requirements aid maintenance planning, replacement schedules and traceability of lighting components in aerospace systems.

By standardizing electrical, dimensional and marking requirements, EN 2240-011:2010 helps ensure interchangeability, safety and predictable performance of Lamp, code 85 across aerospace platforms.

Related Standards

• EN 2756 - Aerospace series - Lamps, incandescent - Tests (used together with EN 2240-011)
• EN 2240-001 - Technical specification (referenced for detailed technical requirements)
• EN 2240-002 - Main characteristics (designation and code rules)
• EN 2241 - Lamp caps - Dimensions

For implementation, consult the referenced parts of the EN 2240 series and EN 2756 to align testing, designation and manufacturing processes with the product standard.
