prEN 1317-7

Road restraint systems - Part 7: Performance classes, impact test acceptance criteria and test methods for terminals of safety barriers

This part of EN 1317 specifies requirements on the impact performance of terminals, performance classes, lateral displacement, vehicle redirection classes, terminal direction classes, VCDI and impact severity levels.
NOTE   This European Standard should be read in conjunction with EN 1317-1. Both these standards support EN 1317-5.
The modifications included in this European Standard are not a change of test criteria, in the sense of the EN 1317-5:2007+A2:2012, ZA.3.
The performance of a terminal in general is dependent on the barrier connected.

Rückhaltesysteme an Straßen - Teil 7:Leistungsklassen, Abnahmekriterien für Anprallprüfungen und Prüfverfahren für Anfangs- und Endkonstruktionen für Schutzeinrichtungen

Dieser Teil von EN 1317 legt Anforderungen an die Leistungsfähigkeit von Anfangs-/Endkonstruktionen, Leistungsklassen, seitliche Verschiebung, Rückleitungsklassen für Fahrzeuge, Richtungsklassen für Anfangs-/Endkonstruktionen, VCDI und Stufen der Anprallheftigkeit fest.
ANMERKUNG   Dieser Teil der Normenreihe sollte in Verbindung mit EN 1317-1 gelesen werden. Beide Teile der Normenreihe unterstützen EN 1317-5.
Die in dieser Europäischen Norm enthaltenen Änderungen beinhalten keine Änderung der Prüfkriterien im Sinne von EN 1317-5:2007+A2:2012, ZA.3.
Die Leistung einer Anfangs-/Endkonstruktion ist im Allgemeinen von der mit ihr verbundenen Schutzeinrich-tung abhängig.

La présente partie de l’EN 1317 spécifie les exigences concernant la performance au choc des extrémités, les classes de performance, le déplacement latéral, les classes de redirection des véhicules, les classes de direction des extrémités, le VCDI et les niveaux de sévérité de choc.
NOTE   Il convient de lire la présente Norme européenne conjointement avec l’EN 1317-1. Ces deux normes viennent à l’appui de l’EN 1317-5.
Les modifications incluses dans la présente Norme européenne ne constituent pas un changement de critères d’essai au sens de l’EN 1317 5:2007+A2:2012, ZA.3.
La performance d’une extrémité dépend d’une manière générale de la barrière raccordée.

Foreword
This document (prEN 1317-7:2012) has been prepared by Technical Committee CEN/TC 226 “Road
equipment”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document, with and only with prEN 1317-4:2012, will supersede ENV 1317-4:2001.
This draft part of EN 1317 does not (and cannot) replace ENV 1317-4:2001 in isolation
EN 1317, Road restraint systems, consists of the following parts:
 Part 1: Terminology and general criteria for test methods;
 Part 2: Performance classes, impact test acceptance criteria and test methods for safety barriers
including vehicle parapets;
 Part 3: Performance classes, impact test acceptance criteria and test methods for crash cushions;
 Part 4: Performance classes, impact test acceptance criteria and test methods for transitions and
removable barriers sections;
 Part 5: Road restraint systems – Product requirements and evaluation of conformity for vehicle restraint
systems;
 Part 6: Pedestrian restraint system – Pedestrian restraint systems – Pedestrian parapets (CEN/TR);
 Part 7: Performance classes, impact test acceptance criteria and test methods for terminals of safety
barriers;
 Part 8: Motorcycle road restraint systems which reduce the impact severity of motorcyclist collisions with
safety barriers (CEN/TS).
This part of EN 1317 is to be read in conjunction with EN 1317-1.
Introduction
The design purpose of safety barriers installed on roads is to contain errant vehicles that either leave the
carriageway or are likely to encroach into the path of oncoming vehicles. EN 1317-2 deals with the impact
performance of a safety barrier to which a terminal may be attached.
Terminals, which are defined as the beginning and/or end treatment of a safety barrier, are required to have
specified impact performances without introducing additional hazards for passenger cars.
The description of a terminal conforming to this European Standard incorporates the relevant classes and
performance levels of the product.
Manufacturers may wish to modify their products or use them with different barriers following the ITT and 5.3,
6.2.1.5 and Annex A of EN 1317-5:2007+A2:2012 set out the procedure to be followed.
1 Scope
This part of EN 1317 specifies requirements on the impact performance of terminals, performance classes,
lateral displacement, vehicle redirection classes, terminal direction classes, VCDI and impact severity levels.
NOTE This European Standard should be read in conjunction with EN 1317-1. Both these standards support
EN 1317-5.
The modifications included in this European Standard are not a change of test criteria, in the sense of the
EN 1317-5:2007+A2:2012, ZA.3.
The performance of a terminal in general is dependent on the barrier connected.
