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.

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.
