Publication date:   Oct 23, 2003

Scope

This prestandard specifies general requirements for classification of flashing light systems used on airports or for ground based aviation lighting systems, for the luminaries, for the control cabinets and for their mechanical and electrical construction erection, together with the related tests. This prestandard is applicable to flashing light systems used for: - Sequential flashing approach lighting systems; - Runway threshold identification lights; - Runway lead-in lighting systems; - Medium and high intensity obstruction lighting systems. Alternately flashing lights used as runway guard lights are excluded from this prestandard. Attention is drawn to the fact that this prestandard covers all aspects of safety (electrical, thermal and mechanical). The purpose of this prestandard is to provide a set of requirements and tests which are applicable to the luminaries and their control equipment. In general, this prestandard covers safety requirements for all components of the system.
