Fixed, vertical road traffic signs - Part 1: Fixed signs
This part of EN 12899:2001 specifies requirements for new fixed signs :
3 non-retroreflective and retroreflective fixed signs ;
3 non-retroreflective and retroreflective fixed signs when they are illuminated at night by external lighting luminaires ; and
3 transilluminated signs.
The main intended use of fixed signs is for the instruction and guidance of road users on public and private land.
It defines performance limits and a range of performance classes for both sign assemblies without vertical supports and assemblies complete with vertical supports, as well as sign faces and supporting substrates, sign fixings and supports and external lighting luminaires.
Colorimetric and retroreflective properties as well as the luminance are specified. The retroreflective properties are in respect of materials based on the use of glass bead technology only. Structural requirements for signs and sign supports include performance under static and dynamic loading.
It also defines performance levels to be maintained after natural weathering exposure.
NOTE Where tests for extremely low temperatures are required they should be in accordance with the customer's requirements.
Ortsfeste, vertikale Straßenverkehrszeichen - Teil 1: Ortsfeste Verkehrszeichen
Dieser Teil der Europäischen Norm EN 12899:2001 legt die Anforderungen an neue, ortsfeste
Verkehrszeichen fest:
? nicht-retroreflektierende und retroreflektierende ortsfeste Verkehrszeichen;
? nicht-retroreflektierende und retroreflektierende, bei Nacht von außen beleuchtete ortsfeste Ver-kehrszeichen;
? innenbeleuchtete Verkehrszeichen.
Benutzer öffentlicher und privater Verkehrswege werden durch die ortsfesten Verkehrszeichen infor-miert
und geführt.
Die Norm legt Mindestanforderungen und eine Reihe von Leistungsklassen für Verkehrszeichen-systeme
mit und ohne Aufstellvorrichtungen sowie für das Signalbild, den Bildträger, Schildbefestigung
und Aufstellvorrichtung sowie Beleuchtungseinrichtungen fest.

Anforderungen hinsichtlich Retroreflektion gelten nur für Materialien, die auf der Technologie von Glas-perlen
beruhen. Konstruktionsanforderungen an Verkehrszeichen und Verkehrszeichenhalterungen
schließen deren Eigenschaften unter statischen und dynamischen Belastungen ein.
Sie legt ebenfalls Leistungsklassen fest, die nach einer natürlichen Bewitterung eingehalten werden
müssen.
ANMERKUNG Wenn Prüfungen bezüglich extrem niedriger Temperaturen gefordert sind, sollten diese nach den
Anforderungen des Auftraggebers ausgeführt werden.
Diese Norm fordert nicht, bereits aufgestellte Verkehrszeichen auszutauschen.
Produkte und Anforderungen, die nicht Gegenstand dieser Norm sind:
a) Schilderbrücken, Kragarme und Fundamente;

e) Anforderungen an die passive Schutzeinrichtung von Aufstellvorrichtungen bezüglich Fahrzeug-anprall;
f) temporäre Beschilderung.
Signaux fixes de signalisation routiere verticale - Partie 1: Panneaux fixes
Cette partie de la norme européenne EN 12899:2001 spécifie les exigences pour les panneaux fixes neufs :
3 panneaux fixes rétroréfléchissants et non rétroréfléchissants ;
3 panneaux fixes rétroréfléchissants et non rétroréfléchissants éclairés la nuit par des luminaires d'éclairage extérieurs ; et
3 caissons lumineux.
Les panneaux fixes sont principalement destinés a orienter et a guider les usagers de la route sur les réseaux publics et privés.
Elle définit les limites de performances et une gamme de classes de performances pour les ensembles de panneaux sans supports verticaux et les ensembles complets avec supports verticaux, ainsi que pour les faces de panneaux et les subjectiles, les fixations et supports, et les luminaires d'éclairage extérieurs.
Les propriétés de colorimétrie et de rétroréflexion, de meme que la luminance, sont spécifiées. En ce qui concerne les matériaux, les propriétés de rétroréflexion sont basées uniquement sur l'utilisation de la technologie des microbilles de verre. Les exigences mécaniques pour les panneaux et leurs supports incluent les performances sous charge statique et dynamique.
Elle définit également les niveaux de performances a maintenir apres un vieillissement climatique naturel.
NOTE Lorsque des essais a tres basses températures sont requis, il convient qu'ils soient réalisés conformément aux exigences du client.
