SIST EN 2240-050:2010

Overview

SIST EN 2240-050:2010 is a European standard developed by CEN that defines the product requirements for the aerospace incandescent lamp, specifically lamp code 1064. This standard sets the essential characteristics needed for lamps used in aerospace applications, ensuring reliability, safety, and performance. It is a crucial document for manufacturers, suppliers, and engineers involved in aerospace lighting components.

The standard should be used in conjunction with EN 2756, which covers test methods for incandescent lamps in aerospace. It also references other related standards such as EN 2240-001 for technical specifications and EN 2240-002 for main characteristics.

Key Topics

• Scope and Application
  Defines mandatory characteristics for incandescent lamp code 1064 used in aerospace environments, focusing on controlled quality and compliance.

• Dimensions and Mass
  Specifies precise physical dimensions, including light center length (LCL) and mass, to ensure interchangeability and fit within aerospace systems.

• Electrical Characteristics

  • Nominal voltage: 14 V
  • Nominal current: 0.02 A
  • Nominal power: 0.28 W
  • Nominal luminous flux: 0.57 lumens
