Road restraint systems - Part 4: Performance classes, impact test acceptance criteria and test methods for transitions and removable barrier sections

This part of EN 1317 is a supporting standard to EN 1317-5 and should also be read in conjunction with EN 1317-1 and EN 1317-2.
This part of EN 1317 completes EN 1317-2 because it specifies performance for transitions, considered as the linkage between safety barriers of different types.
This European Standard specifies the direction of impact and the impact points, for the assessment of transitions and removable barrier sections. It also defines the rules to be followed in the design of transitions that cannot be CE marking.

Rückhaltesysteme an Straßen - Teil 4: Leistungsklassen, Abnahmekriterien und Anprallprüfungen für Übergangskonstruktionen von Schutzeinrichtungen

Dieser Teil von EN 1317 unterstützt EN 1317-5 und sollte außerdem zusammen mit EN 1317-1 und
EN 1317-2 gelesen werden.
Dieser Teil von EN 1317 vervollständigt EN 1317-2, da er die Leistung von Übergangskonstruktionen, die als
Verbindung zwischen Schutzeinrichtungen unterschiedlichen Typs gelten, spezifiziert.
Diese Europäische Norm spezifiziert Anprallrichtung und Anprallpunkte zum Zwecke einer Bewertung von
Übergangskonstruktionen und herausnehmbaren Schutzeinrichtungsabschnitten. Sie legt zugleich Regeln für
die konstruktive Ausführung von Übergangskonstruktionen, die nicht der CE-Kennzeichnung unterliegen, fest.

Dispositifs de retenue routiers - Partie 4 : Classes de performance, critères d’acceptation des essais de choc et méthodes d’essai pour les raccordements et les sections de barrière amovibles

La présente partie de l’EN 1317 vient à l’appui de l’EN 1317-5 et il convient de la lire conjointement avec
l’EN 1317-1 et l’EN 1317-2.
La présente partie de l’EN 1317 complète l’EN 1317-2 car elle spécifie la performance des raccordements,
considérés comme la jonction entre les barrières de sécurité de types différents.
La présente Norme européenne spécifie la direction du choc et les points d’impact pour l’évaluation des
raccordements et des sections de barrière amovibles. Elle définit également les règles à respecter pour la
conception des raccordements qui ne peuvent pas comporter de marquage CE.

Foreword

This document (prEN 1317-4:2012) 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 will supersede ENV 1317-4:2001 for the clauses concerning transitions.

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 and EN 1317-2.

Introduction

In order to improve safety, the design of roads may require the installation of safety barriers including parapets

which are intended to contain and redirect errant vehicles safely for the benefit of the occupants and other

road users on sections of road and at particular locations defined by the National or Local Authorities.

Problems may also arise in the connection between two different safety barriers having consistent difference

in design and/or in stiffness. Transitions are required to provide a smooth and safe change from one barrier to

the other.

This European Standard specifies the direction of impact, and the methods for determining the critical impact

points, for the assessment of transitions.

Manufacturers may wish to modify their products following the ITT and 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 is a supporting standard to EN 1317-5 and should also be read in conjunction with

EN 1317-1 and EN 1317-2.

This part of EN 1317 completes EN 1317-2 because it specifies performance for transitions, considered as the

linkage between safety barriers of different types.

This European Standard specifies the direction of impact and the impact points, for the assessment of

transitions and removable barrier sections. It also defines the rules to be followed in the design of transitions

that cannot be CE marking.
