Road traffic signal systems - Electromagnetic compatibility

This product standard for EMC requirements applies to road traffic signal systems. The range of products included within the scope of this European Standard are road traffic signal systems and devices including for example signal heads, signalling devices and traffic signs, controller and housing, supports, interconnections, traffic detectors, monitoring equipment, electrical supply. Road traffic signal systems operating in conjunction with other systems e.g. public lighting, railway systems should also comply with the respective standard and should not reduce the safety of all the equipment. Central Office equipment is excluded from this standard. Items with a radio-communication function should also refer to the European ETSI standards.

Straßenverkehrs-Signalanlagen - Elektromagnetische Verträglichkeit

Diese Produktnorm für EMV-Anforderungen (EMV = Elektromagnetische Verträglichkeit) gilt für Straßenver-kehrs-Signalanlagen. Produkte, die im Anwen¬dungsbereich dieser Norm enthalten sind, sind Verkehrs-Sig-nalanlagen einschließlich zugehöriger Geräte, z. B. Signalgeber, Signalisierungsgeräte und Verkehrsschilder, Steuergeräte und Gehäuse, Maste, Verbin¬dungen, Verkehrsdetektoren, Überwachungsgeräte, Stromversor¬gung. Straßenverkehrs-Signalanlagen, die in Verbindung mit anderen Anlagen arbeiten, z. B. öffentliche Be¬leuchtung, Eisenbahnen, müssen ebenfalls mit der entsprechenden Norm übereinstimmen und dürfen die Sicherheit der gesamten Anlage nicht vermindern. Büroausrüstung ist von dieser Norm ausgeschlossen. In jeder Hinsicht müssen Teile mit Funkübertragungs¬funktionen auch den Europäischen ETSI-Normen ent¬sprechen.

Systèmes de signaux de circulation routière - Compatibilité électromagnétique

La présente norme de produits en matière d'exigences CEM s'applique aux systèmes de signaux de circulation routière. La gamme de produits incluse dans le domaine d'application de la présente Norme européenne comprend les systèmes de signaux de circulation routière, notamment, par exemple, les signaux, dispositifs de signalisation et panneaux de circulation, les contrôleurs et les enveloppes, les supports, les interconnexions, les détecteurs et équipements de contrôle de trafic, l'alimentation électrique. Il convient que les systèmes de signaux de circulation routière qui fonctionnent conjointement avec d'autres systèmes, par exemple l'éclairage public, les systèmes ferroviaires, soient également conformes aux normes applicables et ne réduisent pas la sécurité de l'ensemble de l'équipement. Les équipements de postes centraux sont exclus de cette norme. Il convient que les éléments ayant une fonction de radiocommunication fassent également référence aux normes européennes ETSI.

Sistemi prometne signalizacije - Elektromagnetna združljivost

Ta standard za izdelek za zahteve glede elektromagnetne združljivosti (EMC) velja za sisteme prometne signalizacije. Vrste izdelkov, ki spadajo na področje uporabe tega evropskega standarda, so sistemi prometne signalizacije in naprave, ki vključujejo na primer signalne luči, signalne naprave in prometne znake, regulator in ohišje, nosilce, povezovalnike, prometne detektorje, opremo za spremljanje ter oskrbo z elektriko. Sistemi prometne signalizacije, ki delujejo skupaj z drugimi sistemi, npr. javno razsvetljavo, železniškimi sistemi, morajo izpolnjevati tudi ustrezni standard in ne smejo zmanjšati varnosti celotne opreme. Oprema centralnega urada je izvzeta iz tega standarda. Enote z radijsko zvezo se morajo prav tako nanašati na evropske standarde ETSI.

4 Common test conditions

In general the EMC testing of equipment requires it to be operated under conditions similar to those which

would be found in practice. Equipment may be tested individually or in a representative system as

described below.

The modes of operation that are likely to cause highest levels of emission and in addition those likely to

give rise to the most susceptible condition shall be selected. The equipment under test will be tested in

such a manner so as to maximise emission and susceptibility levels at the highest operational frequencies.

Equipment having dimmed and undimmed conditions of operation shall be tested in that condition which

produces the higher emission level.

For traffic controllers, tests shall be carried out in a system configuration as described in 5.6 with standard

loads and standard cycles as defined in 5.4 and 5.5. The standard loads do not need to be installed in the

test chamber.

Details of the test configuration and the length of the interconnecting cables used shall be included in the

test report.
5 Test configuration
5.1 Equipment
The equipment shall be a standard production version.

5.2 Supplier
The supplier shall specify the functions of the equipment.
5.3 Technical documentation
The equipment shall be accompanied by the necessary technical documentation.

This documentation shall at least define modes of operation, the configuration details for the test, the

technical specification and installation details sufficient to repeat the test.
5.4 Standard load

For controller or system tests the controller shall be set for two signal group operations.

One signal group shall be connected to the maximum load and the other to the minimum load. These loads

shall be either the standard signal heads together with their associated control gear or an electrical

equivalent load.
5.5 Cycle rate

The cycle rate for vehicle controller shall be adjusted such that a minimum of three switching o
