BS EN 50490:2008 PDF Download

BS EN 50490:2008 is a standard that specifies the technical requirements for aeronautical ground lighting (AGL) control and monitoring systems. Specifically, it focuses on units used for selective switching and monitoring of individual lamps in an AGL series circuit. The standard provides general minimum frame requirements for these units, regardless of the technology employed for switching and monitoring.

The scope of BS EN 50490 encompasses units that are directly electrically connected to the primary or secondary side of an AGL series circuit. These units are crucial for the selective switching and monitoring of lamps. However, the standard does not cover communication protocols, application procedures, or system aspects that may impact the operation of AGL.

The document is structured into several sections, including scope, normative references, definitions, general requirements, electrical connections, enclosure specifications (for both indoor and outdoor units), mechanical impact protection, earthing, service temperature and humidity considerations, reliability, electrical characteristics, marking, and functional requirements. It also covers type and routine tests that need to be performed to ensure compliance with the standard.
