SIST EN 2240-064:2011

Overview

SIST EN 2240-064:2011 is a European standard developed by CEN (European Committee for Standardization) that specifies the required characteristics for the incandescent lamp coded 1819 designed explicitly for aerospace applications. This product standard is part of the Aerospace series focused on incandescent lamps and complements the technical guidelines detailed in EN 2756. It ensures the lamps meet stringent quality, reliability, and performance criteria essential in aerospace environments where safety and durability are critical.

This standard is mandatory for manufacturers and users involved in aerospace electric equipment and systems to guarantee interoperability and compliance across European aerospace sectors.

Key Topics
