Overview

SIST EN 2240-070:2011 is a European Standard developed by the European Committee for Standardization (CEN) that defines the product requirements for incandescent lamps specifically designed for aerospace applications. This standard pertains to lamp code 2232 and outlines the essential characteristics to ensure suitability, safety, and reliability in the demanding aerospace environment. It is intended to be used in conjunction with EN 2756, which covers test methods for aerospace incandescent lamps. SIST EN 2240-070:2011 is part of the broader EN 2240 series focused on incandescent lamps in aerospace systems.

Key Topics

• Scope and Application
  SIST EN 2240-070:2011 applies exclusively to incandescent lamps code 2232 used in aerospace electric equipment and systems. It sets out the mandatory requirements for lamp characteristics to guarantee consistent performance under aerospace operating conditions.

• Required Characteristics
  The standard specifies critical physical and electrical parameters including:

  • Dimensions and mass (e.g., light centre length 30.2 ± 1.5 mm, mass 8.5 kg per 1,000 lamps)
  • Electrical ratings such as nominal voltage (28 V), nominal current (0.643 A), and power (18 W)
  • Photometric data, including nominal luminous flux of 226 lumens and color temperature around 2,620 K
  • Life expectancy specified for static and dynamic conditions with both direct current (DC) and alternating current (AC), ensuring durability in aerospace environments
  • Filament design conforms with EN 2240-002 for filament form consistency
  • Cap type BA15s/19 as per EN 2241 standards

• Designation and Marking
  Lamps must be clearly identified using a coding system based on EN 2240-002, which includes the basic standard number and lamp code. Markings on the lamp and packaging enable traceability and compliance verification.

• Normative References
  SIST EN 2240-070:2011 references complementary parts of EN 2240 series for technical specifications, main characteristics, and dimensions, plus EN 2756 for testing procedures.

Applications

• Aerospace Electrical Systems
  The lamp covered under SIST EN 2240-070:2011 serves as a standardized lighting element in aerospace equipment, including cockpit instrumentation, external and internal aircraft lighting, and signaling devices. The strict performance criteria support safety, operational reliability, and maintenance consistency across aerospace platforms.

• Replacement and Maintenance
  Standardized lamp features allow technicians and engineers to replace lamps without concern for fit or performance discrepancies, simplifying maintenance protocols in commercial and defense aerospace operations.

• Product Development and Quality Assurance
  Manufacturers developing incandescent lamps for aerospace purposes rely on SIST EN 2240-070:2011 to align product design and testing with recognized certification criteria, facilitating market acceptance across European and global aerospace sectors.
