Over deze norm
This document specifies requirements and test methods for new Variable Message Signs (VMS). VMS comprise two types, continuous and discontinuous signs: - continuous signs are those that are similar to fixed signs, the only difference being that by some electro-mechanical means they can show various messages. The EMC, safety and environmental requirements for both types of VMS are included in this document together with the visual performance for the discontinuous types VMS. The visual performance for continuous signs and !externally illuminated" discontinuous signs which are externally illuminated is covered by EN 12899-1. This document defines performance limits and a range of performance classes for both sign assemblies without vertical support and assemblies complete with vertical support. Not covered by this document are: a) sign gantries, cantilevers and foundations; !deleted text" b) signal heads; c) sizes and shapes of VMS messages; d) control units and monitoring units unless inside the test module; !e) sign luminance control. The control of the luminance of luminous signs with respect to the ambient light is not covered by this standard."
