Passive safety of support structures for road equipment - Requirements, classification and test methods
This European Standard specifies performance requirements and defines levels in passive safety terms intended to reduce the severity of injury to the occupants of vehicles impacting with the permanent road equipment support structures. Consideration is also given to other traffic and pedestrians. Three energy absorption types are considered and test methods for determining the level of performance under various conditions of impact are given.
This European Standard excludes vehicle restraint systems, noise barriers and transilluminated traffic bollards. It also excludes temporary traffic control devices.
Passive Sicherheit von Tragkonstruktionen für die Straßenausstattung - Anforderungen und Prüfverfahren
Diese Europäische Norm legt Leistungsanforderungen fest und definiert Leistungsklassen hinsichtlich der passiven Sicherheit, mit dem Ziel, den Grad der Verletzungen, die Fahrzeuginsassen beim Anprall an eine dauerhafte Tragkonstruktion für die Straßenausstattung erleiden können, zu vermindern. Dabei werden andere Fahrzeuge sowie Fußgänger ebenfalls berücksichtigt. Es werden drei Arten der Energieabsorption behandelt. Prüfverfahren zur Bestimmung der Leistungsklassen unter verschiedenen Anprallbedingungen sind angegeben.
Fahrzeugrückhaltesysteme, Lärmschutzwände und innen beleuchtete Verkehrsleitsäulen sind nicht Gegenstand dieser Norm. Die Norm gilt ebenfalls nicht für Gegenstände, die zur vorübergehenden Führung des Verkehrs in Arbeitsstellen eingesetzt werden.

La présente Norme européenne spécifie les exigences de performances et définit les niveaux en termes de
sécurité passive destinés à réduire la gravité des blessures des occupants de véhicules en cas d'impact avec
les structures supports des équipements de la route permanents. D'autres éléments comme la circulation et
les piétons sont également pris en compte. La présente norme considère trois types d'absorption d'énergie et
définit des méthodes d'essai pour déterminer le niveau de performance dans différentes conditions d'impact.
La présente Norme européenne exclut les dispositifs de retenue des véhicules, les barrières antibruit et les
bornes lumineuses, ainsi que les dispositifs de signalisation temporaire de chantier.

4 Introduction The severities of accidents for vehicle occupants are affected by the performance of support structures for items of road equipment under impact. Based on safety considerations, these can be made in such a way that they detach or yield under vehicle impact. This European Standard provides a common basis for testing of vehicle impacts with items of road equipment support. This European standard considers three categories of passive safety support structures: high energy absorbing (HE); low energy absorbing (LE); non-energy absorbing (NE). Energy absorbing support structures slow the vehicle considerably and thus the risk of secondary accidents with structures, trees, pedestrians and other road users can be reduced. Non-energy absorbing support structures permit the vehicle to continue after the impact with a limited reduction in speed. Non-energy absorbing support structures may provide a lower primary injury risk than energy absorbing support structures. In this European Standard, several levels of performance are given using the two main criteria related to the performance under impact of each of the three energy absorbing categories of support structure. Support structures with no performance requirements for passive safety are class 0. There are four levels of occupant safety. Levels 1, 2 and 3 provide increasing levels of safety in that order by reducing impact severity. For these levels two tests are required: test at 35 km/h to ensure satisfactory functioning of the support structure at low speed. test at the class impact speed (50, 70 and 100) as given in Table 1. Level 4 comprises very safe support structures classified by means of a simplified test at the class impact speed. All the tests use a light vehicle to verify that impact severity levels are satisfactorily attained and compatible with safety for occupants of a light vehicle. The different occupant safety levels and the energy absorption categories will enable national and local road authorities to specify the performance level of an item of road equipment support structures in terms of the effect on occupants of a vehicle impacting with the structure. Factors to be taken into consideration include: perceived injury accident risk and probable cost benefit; type of road and its geometrical layout; typical vehicle speeds at the location; presence of other structures, trees and pedestrians; presence of vehicle restraint systems.
1 Scope This European Standard specifies performance requirements and defines levels in passive safety terms intended to reduce the severity of injury to the occupants of vehicles impacting with the permanent road equipment support structures. Consideration is also given to other traffic and pedestrians. Three energy absorption types are considered and test methods for determining the level of performance under various conditions of impact are given. This European Standard excludes vehicle restraint systems, noise barriers and transilluminated traffic bollards. It also excludes temporary traffic control devices. 2 Normative references The following referenced documents are indispensable for the application of this document.
