SIST EN 2240-069:2011

Overview

SIST EN 2240-069:2011 is a European standard published by CEN that specifies the required characteristics for aerospace incandescent lamps, specifically lamp code 1978. This product standard is part of the broader EN 2240 series dedicated to incandescent lamps used in aerospace applications. It ensures that these lamps meet stringent quality, safety, and performance criteria essential for aerospace systems. The standard should be used in conjunction with EN 2756, which details test methods for these lamps.

The standard has been developed by the Aerospace and Defence Industries Association of Europe (ASD-STAN) and mandates harmonized requirements across CEN member countries. It applies to lamps used in aerospace electrical and lighting systems where reliability and precision are critical.

Key Topics

• Scope and Application
  This standard exclusively targets incandescent lamps with the identification code 1978 designed for aerospace uses. It defines technical specifications related to dimensions, performance, and marking to facilitate uniformity and interchangeability.

• Lamp Characteristics
  Includes detailed requirements on:

  • Dimensions and Mass: Precise size specifications in millimeters to ensure compatibility with aerospace equipment.
  • Electrical Ratings: Voltage, current, and power specifications under nominal operating conditions.
  • Light Output: Nominal luminous flux and color temperature parameters to guarantee consistent light quality.
  • Lifespan: Defined static and dynamic life expectancies under DC and AC operating conditions.
  • Filament Form: Specification of filament shape according to EN 2240-002 to influence durability and light distribution.
  • Cap Design: Defined to standardize mounting and electrical connection.

• Designation and Marking
  The lamp and packaging must be marked with an international code number per EN 2240-002, ensuring traceability and proper identification throughout supply and maintenance chains.

• Normative References
  This standard works in conjunction with:

  • EN 2240-001 – Technical Specification for incandescent lamps
  • EN 2240-002 – Main Characteristics and Codes of lamps
  • EN 2756 – Test Methods for incandescent aerospace lamps

Applications

SIST EN 2240-069:2011 lamps are essential components for a variety of aerospace systems, including:

• Aircraft lighting systems – indicator, signal, and cockpit illumination relying on reliable incandescent lamps conforming to aerospace standards.
• Aerospace instrumentation and control panels – where consistent lamp performance ensures accurate indication and system monitoring.
• Maintenance and replacements – standardized lamps simplify stocking, ordering, and installation in aerospace manufacturing and upkeep environments.

Adhering to this standard supports enhanced operational safety, reduces equipment failures, and facilitates interoperability in multi-national aerospace projects.
