Overview

EN 2240-089:2011 is a European Standard that specifies the required characteristics for an incandescent lamp, identified by code A7512-24, designed specifically for aerospace applications. Developed by the Aerospace and Defence Industries Association of Europe (ASD-STAN) and approved by the European Committee for Standardization (CEN), this standard ensures precise technical requirements and consistent quality for aerospace incandescent lamps. The standard must be used in conjunction with EN 2756, which covers test methods for aerospace incandescent lamps.

This product standard focuses on essential aspects such as lamp dimensions, electrical performance, luminous intensity, lifespan, filament form, and marking, ensuring compatibility and reliability in critical aerospace electrical systems.

Key Topics

• Scope and Application
  EN 2240-089:2011 applies exclusively to the lamp with code A7512-24 for aerospace use. It complements other standards under the EN 2240 series, particularly EN 2756 for testing.

• Dimensions and Physical Characteristics
  The lamp’s dimensions are specified in millimetres, with exact tolerances to ensure fit and function in aerospace equipment. Key features include:

  • Light Centre Length (LCL): 29.4 ± 1 mm
  • Mass (for 1000 lamps): 10 kg
  • Silvered bulb appearance for optimized light emission

• Electrical and Optical Specifications
  The lamp operates at a nominal voltage of 28 V, with a nominal current of 0.93 A and power consumption of 26 W. Its luminous performance is characterized by:

  • Luminous intensity of 200 cd in primary direction (C1) and 25 cd in secondary direction (C2)
  • Colour temperature of approximately 2760 K
  • Static life span: 300 hours with DC, 400 hours with AC
  • Dynamic life span: 150 hours with DC

• Filament and Cap Type
  The filament has a specific form defined in EN 2240-002 (CC - 6), and the cap type is BAY15s/19, standardized under EN 2241.

• Marking and Identification
  Both the lamp and its packaging must be clearly marked with the international code number according to EN 2240-002, facilitating traceability and compliance.

Applications

This standard is crucial for manufacturers, suppliers, and quality inspectors involved in aerospace lighting components. Applications include:

• Aircraft lighting systems
  Ensures safe and reliable incandescent lamps suitable for cockpit, cabin, and external aircraft lighting.

• Aerospace equipment manufacturers
  Facilitate compatibility and standardization across aerospace electric equipment.

• Maintenance and replacement parts
  Provide clear specifications for sourcing certified replacement lamps in aerospace maintenance operations.

• Quality assurance and certification
  Support compliance with rigorous aerospace safety and performance standards by defining test methods and product requirements.

Related Standards

To ensure comprehensive adherence and compatibility, EN 2240-089:2011 is used alongside several related standards from the EN 2240 series:

• EN 2756 – Aerospace series - Lamps, incandescent: Test methods
• EN 2240-001 – Aerospace series - Lamps, incandescent: Technical specification
• EN 2240-002 – Aerospace series - Lamps, incandescent: Main characteristics
• EN 2241 – Aerospace series - Lamp caps: Dimensions

These interconnected standards provide a full framework covering lamp design, testing, identification, and performance criteria essential for aerospace incandescent lamps.
