Road vertical signs - Variable message traffic signs
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. NOTE 1 For example rotating prism signs, roller blinds. - discontinuous signs create messages 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 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 included 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 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 inside the test module.
Vertikale Verkehrszeichen - Wechselverkehrszeichen
Diese Europäische Norm enthält Festlegungen zu zwei Arten von Wechselverkehrszeichen (WVZ); d. h. zu kontinuierlichen (siehe 3.4) und disnicht kontinuierlichen (siehe 3.7) Wechselverkehrszeichen.
Diese Europäische Norm behandelt mobile, temporäre und dauerhaft aufgestellte WVZ, die auf Verkehrs¬flächen, auf öffentlichem oder privatem Gelände, einschließlich in Tunneln, zur Information, als Leitlinie, Warnhinweis und/oder Richtungsanzeige aufgestellt werden. Prüfmodule werden verwendet, um die Überein¬stimmung mit den Anforderungen nachzuweisen.
Diese Europäische Norm legt die visuellen und physikalischen Merkmale von WVZ sowie deren Dauerhaftig-keitsaspekte fest. Sie enthält außerdem die maßgeblichen Anforderungen und die entsprechenden Prüf¬verfahren, die Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP) und die Kennzeichnung.
ANMERKUNG Die Bestimmungen zur Bewertung der Konformität im Hinblick auf die Typprüfung werden ausführlicher in 6.2 beschrieben; Bestimmungen im Hinblick auf die werkseigene Produktionskontrolle (WPK) werden ausführlicher in 6.3 beschrieben.
Diese Europäische Norm behandelt keine:
a) Schilderbrücken, Ausleger, Maste (Träger) und Fundamente;
b) Signalgeber;
c) Größen und Formen von WVZ-Zeicheninhalten;
d) Bedienungs und Überwachungseinheiten, es sei denn, sie befinden sich im WVZ;
e) Steuerung der Leuchtdichte von Verkehrszeichen.
Signaux de signalisation routière verticale - Panneaux à messages variables
La présente Norme européenne spécifie des spécifications pour les deux types de panneaux à messages variables (PMV) existants : les panneaux continus (voir 3.4) et les panneaux discontinus (voir 3.6).

Des modules d'essai sont utilisés pour démontrer la conformité aux exigences.
La présente Norme européenne ne couvre pas :
a) les portiques, potences, poteaux (supports) et fondations de panneaux,
b) les têtes de feux,
c) les tailles et les formes des messages des PMV,
d) les organes de contrôle et de surveillance à l'exception de ceux intégrés au module d'essai,
e) le contrôle de la luminance des panneaux.
Pokončni cestni znaki - Prometni znaki s spremenljivo vsebino
Ta dokument navaja zahteve in preskusne metode za nove prometne znake s spremenljivo vsebino (VMS). Prometni znaki s spremenljivo vsebino vključujejo dve vrsti znakov, neprekinjene in prekinjene: – neprekinjeni znaki so tisti, ki so podobni fiksnim znakom, le da lahko z nekaterimi elektro-mehanskimi sredstvi prikazujejo različna sporočila. OPOMBA 1 Na primer znaki, v katerih so uporabljene optične prizme, rolete. – prekinjeni znaki ustvarjajo sporočila z uporabo posameznih elementov, ki so lahko v eni od dveh oblik (ali več) in s tem ustvarjajo različna sporočila na isti površini znaka. OPOMBA 2 Na primer znaki z optičnimi vlakni, LED. Ta dokument zajema zahteve glede delovanja znakov s spremenljivo vsebino, ki se uporabljajo za navodila in usmerjanje udeležencev v cestnem prometu na javnih in zasebnih zemljiščih, vključno s predori. V tem dokumentu so obravnavane številne različne zahteve delovanja (vizualno delovanje, EMC, vpliv na okolje itd.) in tudi trajnost. V tem dokumentu so zahteve za EMC, varnost in zaščito okolja za obe vrsti prometnih znakov, skupaj z vizualnim delovanjem za prekinjene vrste prometnih znakov s spremenljivo vsebino. Vidno delovanje za neprekinjene in prekinjene znake, ki so osvetljeni od zunaj, je vključeno v standard EN 12899-1. Ta dokument določa omejitve in različne razrede delovanja za oba sklopa znakov brez vertikalne podpore in sklope skupaj z navpično podporo. Dokument ne zajema: a) podstavkov znakov, konzol in temeljev; b) prenosnih in začasnih prometnih znakov s spremenljivo vsebino; c) signalnih glav; d) velikosti in oblik sporočil znakov s spremenljivo vsebino; e) enot za nadzor in spremljanje, razen če so v preskusnem modulu.
