(Main)Traffic control equipment - Warning and safety light devices
Traffic control equipment - Warning and safety light devices
This European Standard specifies the requirements for individual electrically operated light devices, called warning lights, emitting a continuous or regular intermittent light of a single colour which, by their colour and position alone, are used to warn, inform or guide road users. It specifies the requirements for visual, structural and operational performances and the relevant test methods to be used. These devices rely upon existing furniture to provide the mounting.
This European Standard is not applicable to lighting devices which convey messages by additional means (e.g. variable message signs) or which convey a mandatory instruction (e.g. traffic signals) or which are covered by vehicle lighting regulations.
This European Standard does not consider horizontal loads because it is the mounting to which they are fixed, which is not covered by this European Standard, which has to resist applied horizontal loads.
Anlagen zur Verkehrssteuerung - Warn- und Sicherheitsleuchten
Dieses Dokument legt die Anforderungen an einzelne elektrisch betriebene Leuchtvorrichtungen fest, so genannte Warnleuchten, die ein dauerndes oder regelmäßig intermittierendes Licht einer einzelnen Farbe ausstrahlen und die allein durch ihre Farbe und ihre Position zur Warnung, Information oder Leitung von Verkehrsteilnehmern verwendet werden. Es legt die Anforderungen an die optische Leistung, die bautechnische Ausführung und die Betriebskennwerte sowie die entsprechenden anzuwendenden Prüfverfahren fest. Diese Leuchten sind zur Befestigung an vorhandenen Vorrichtungen vorgesehen.
Dieses Dokument ist nicht anwendbar für Leuchtvorrichtungen, die durch zusätzliche Mittel Nachrichten (z. B. Wechselverkehrszeichen) oder eine verbindliche Anweisung (z. B. Verkehrszeichen) übermitteln oder die Bestimmungen über Fahrzeugscheinwerfer unterliegen.
Dieses Dokument behandelt keine horizontalen Lasten, da die Befestigungen, die die horizontalen Lasten aufnehmen, nicht Gegenstand dieses Dokuments sind.
Equipement de régulation du trafic - Feux de balisage et d'alerte
Le présent document spécifie les exigences relatives aux appareils lumineux électriques individuels (appelés feux d'alerte) émettant une lumière continue ou intermittente régulière monochrome qui, en raison de leur couleur et de leur emplacement, sont utilisés pour avertir, informer ou guider les usagers de la route. Elle spécifie également les exigences en matière de performances visuelles, structurelles et opérationnelles, ainsi que les méthodes d'essai correspondantes à utiliser. Pour le montage, ces appareils reposent sur les équipements fixes existants.
Le présent document ne s'applique pas aux appareils lumineux qui transmettent des messages par des moyens supplémentaires (ex : panneaux à message variable), qui délivrent des instructions obligatoires (ex : feux de circulation) ou qui sont soumis à la réglementation en matière d'éclairage automobile.
Le présent document ne prend pas en compte les charges horizontales, car c'est le support sur lequel les appareils sont fixés (lequel n'est pas couvert par le présent document) qui doit résister aux charges horizontales appliquées.
