SIST EN 2240-026:2010

Overview - EN 2240-026:2010 (Aerospace incandescent lamp, code 330)

EN 2240-026:2010 is a CEN product standard in the Aerospace series that specifies required characteristics for the incandescent lamp, code 330, intended for aerospace applications. This product standard defines dimensional, electrical, photometric and life characteristics and the required marking and designation for consistent procurement, manufacture and verification of this lamp type. It shall be used together with EN 2756 (test methods).

• Cross-references
  • Use alongside EN 2240-001 (technical specification), EN 2240-002 (main characteristics), EN 2241 (lamp caps), and EN 2756 (test methods).

Practical applications and who uses this standard

EN 2240-026:2010 is intended for stakeholders involved with aerospace lighting components who need a consistent, verifiable product definition:

• Aerospace OEMs and suppliers specifying or producing incandescent lamps (code 330)
• Procurement and supply chain teams creating parts specifications and purchase orders
• Quality assurance and test laboratories conducting verification using EN 2756 test methods
• Maintenance, repair and overhaul (MRO) organizations replacing or approving parts
• Regulatory and certification bodies assessing compliance with aerospace electrical equipment norms

Using this product standard helps ensure interchangeability, reliable performance in aircraft systems, and clear contractual specifications.
