This European Standard shall be given the status of a national standard, either by publication of an identical text or b

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of E
18、U Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.

EN 12966-1:2005 (E) 4 Introduction This document is designed for use by Road Authorities and private developers who wish to use variable message signs. I
22、t provides performance requirements and the means of evaluation of conformity to those requirements. This document is a product standard covering the requirements for Variable Message Signs (VMS). A VMS is a sign where the information shown can be changed. The information can be text and/or symbols.
23、 This document does not describe the detailed form and configuration of a VMS. Therefore test modules are used to demonstrate conformance with the requirements of this document because of the impracticality of testing some complete signs. Because of the major demands on a sign for good legibility an
24、d visibility throughout the required viewing range, the main properties of the sign are described. These properties can vary depending on the situation. For example, it will be not necessary to ask for a minimum temperature requirement of -40 C in Greece, but this will be considered in Lapland. For
25、visual performance there will be a difference between installation on highways - with good distance visibility and a narrow beam width - and installation in cities, where there is only short distance legibility and when a wide beam may be required. This document uses performance requirements, which
26、are not dependent on technology. The visual and environmental performance is demonstrated on a test module. This document contains a number of defined requirements, some of which have to be demonstrated on the test module, others that are to be verified by the manufacturer. It is the manufacturers r
27、esponsibility to ensure that the final product is fully representative of the test module. The main properties of VMS are divided into classes, which are designed to be selected by choosing a combination of classes dependent on the situation and purchaser requirements. This combination covers not on
28、ly the regulatory requirements of the territory of destination but also issues of lifetime, quality, maintenance and construction, all of which affect the ability of a sign in its particular application, to meet safety and fitness for purpose. The details in the informative Annexes are provided as u
29、seful guidance on the additional aspects relating to VMS for those setting up purchasing contracts for signs or signing systems. The working environment for VMS can be relatively harsh and equipment that is deemed “fit for purpose“ is expected to last in an exposed, corrosive environment for a minim
30、um of 10 years. It is essential that all materials and manufacturing processes take this into account. The manufacturer should detail all steps taken to comply with this. EN 12966-1:2005 (E) 5 1 Scope This document specifies requirements and test methods for new Variable Message Signs (VMS). VMS com
31、prise 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. NOTE 1 For example rotating prism signs, roller blinds. - discontinuous signs create mess
32、ages using individual elements that can be in one of two states (or more) and can thereby create various messages on the same sign face. NOTE 2 For example fibre optic signs, LED signs. This document covers the performance requirements for Variable Message Signs used for the instruction and guidance
33、 of road users on public and private land, including tunnels. In this document a number of different performance requirements (visual performance, EMC, environmental performance, etc) are covered, as well as durability. The EMC, safety and environmental requirements for both types of VMS are include
34、d in this document together with the visual performance for the discontinuous types VMS. The visual performance for continuous signs and 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
35、 sign assemblies without vertical support and assemblies complete with vertical support. Not covered by this document are: a) sign gantries, cantilevers and foundations; b) portable and temporary VMS; c) signal heads; d) sizes and shapes of VMS messages; e) control units and monitoring units unless
36、inside the test module. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
