Passive safety of support structures for road equipment - Requirements and test methods

This European Standard specifies performance test procedures to determine levels of passive safety intended to reduce the severity of injury to vehicle occupants of a small car in an impact with permanent support structures of road equipment. Test methods for determining the level of performance under various conditions of impact are given.

Passive Sicherheit von Tragkonstruktionen für die Straßenausstattung - Anforderungen und Prüfverfahren

Diese Europäische Norm legt Verfahren zur Bestimmung der Leistung 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. Prüfverfahren zur Bestimmung der Leistungsklassen unter verschiedenen Anprallbedingungen sind angegeben.

Sécurité passive des structures supports d'équipements de la route - Prescriptions, classification et méthodes d'essai

La présente Norme européenne définit les procédures d'essai de résistance en vue de déterminer les niveaux de sécurité passive nécessaires pour réduire la gravité des blessures subies par les passagers d'un véhicule léger en cas d'impact avec les structures de support fixes des équipements routiers. La méthodologie de définition des niveaux de performance sous diverses conditions de choc est communiquée.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 226.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which
stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other language
made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United
Kingdom.
