Overview

The SIST EN 2240-047:2010 standard, developed by the European Committee for Standardization (CEN), is part of the aerospace series focusing on incandescent lamps. This part, titled "Lamp, code 718 - Product standard," specifies the required characteristics for incandescent lamps designated with code 718, primarily used in aerospace applications. The standard ensures consistency, reliability, and quality in these lamps, which are critical components of aerospace electric systems.

SIST EN 2240-047:2010 is intended to be used together with standard EN 2756, which covers test methods for incandescent lamps in aerospace, ensuring that all products meet stringent aerospace industry requirements.

Key Topics

• Scope and Applicability
  Defines the general requirements for incandescent lamp code 718, specifically catering to aerospace equipment where strict operational integrity is needed.

• Dimensions and Physical Characteristics
  Includes precise specifications for the lamp's size and mass, such as:

  • Light center length (LCL): 4.8 ± 0.5 mm
  • Mass for 1,000 lamps: 0.24 kg
  • Bulb appearance: Clear

• Electrical and Optical Properties
  Specifies nominal electrical values to ensure standardized performance:

  • Nominal voltage: 5 V
  • Nominal current: 0.115 A
  • Nominal power: 0.575 W
  • Nominal luminous flux: 1.9 lumens
  • Colour temperature: 1980 K

• Lamp Life
  Defines life expectancy under different conditions such as static and dynamic operation with either direct current (d.c.) or alternating current (a.c.), with lamp hours ranging from 3,000 to 4,000.

• Filament and Cap Specifications
  Refers to related standards EN 2240-002 for filament form and EN 2241 for lamp cap dimensions (SX4s/4).

• Designation and Marking
  Outlines the method to mark lamps and packaging with international code numbers as per EN 2240-002, facilitating traceability and identification.

Applications

SIST EN 2240-047:2010 certified incandescent lamps are used in several critical aerospace applications, including:

• Cockpit and Instrumentation Lighting
  Ensuring reliable illumination under extreme conditions for pilot and crew interfaces.

• Cabin Lighting Systems
  Providing consistent light quality and longevity essential for passenger safety and comfort.

• Signal and Indicator Lamps
  Utilized in various aircraft signaling devices requiring high reliability.

• Backup and Emergency Lighting
  Where dependable incandescent lamps ensure operational readiness in critical situations.

By adhering to these standards, aerospace manufacturers and maintenance providers guarantee performance quality and safety compliance in their lighting systems.

Related Standards

To fully comply and implement lamp code 718 correctly, the following related CEN/ASD-STAN standards should be considered:

• EN 2240-001: Technical specification for incandescent aerospace lamps
• EN 2240-002: Main characteristics of incandescent lamps, including identification codes
• EN 2241: Aerospace series lamp caps - dimensions and compatibility
• EN 2756: Test methods for incandescent lamps in aerospace applications

Combining these standards ensures a comprehensive approach to the design, testing, and usage of incandescent lamps in aerospace systems.
