8 BSI 2006 Licensed copy:Arup, 23/09/2009, Uncontrolled Copy, BSIEN 1317-2:19983 IntroductionIn order to improve safety the design of roads may require the installation of safety barriers which are intended to contain and redirect errant vehicles safely for the benefit of the occupants and other road users on certain sections of road and at particular this standard, several levels of performance are given for the three main criteria relating to the restraint of a road vehicle: the containment level, T1, T2, etc.; the impact severity levels, A and B; the deformation as expressed by the working width, W1, W2, different performance levels of safety barriers will enable national and Local Authorities to specify the performance class of a safety barrier to be deployed. Factors to be taken into consideration include the class or type of road , its location, geometrical layout, the existence of a vulnerable structure, potentially hazardous area or object adjacent to the description of a safety barrier system conforming to this standard incorporates the relevant classes and performance levels of the ensure satisfactory product design it is imperative to consider the requirements of this standard and the references in clause2, together with the requirements of EN 1317-1.

9 Quality of manufacture, installation and durability all contribute to this fulfilment of the important safety criteria that have to be considered in the application of these standard provides a common basis for vehicle impact test data collection and the collation of relevant European studies and research with a view to improving future specifications and reviewing of the measurement of impact ScopeThis European Standard specifies requirements for the impact performance of safety barriers including vehicle parapets. It defines performance classes for different containment levels, acceptance criteria for impact tests and test provisions of this standard apply to systems of which the containment function is the unique purpose of the system . These provisions apply also to systems of which the containment function is an additional purpose of such systems , for example noise barriers and signalling Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.

10 These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to 1317-1, road restraint systems Part 1: Terminology and general criteria for test 6487, road vehicles Measurement techniques in impact tests 10392, road vehicles with two axles Determination of centre of Performance GeneralSafety barriers shall conform to the requirements , when tested in accordance with impact test criteria defined in Table These requirements include several levels of performance that permit selection of a containment system adapted to suit the traffic conditions and the geometrical characteristics of the road under specifications and deviations shall conform to EN 1 Vehicle impact test Containment levelsThe containment levels of safety barriers shall conform to the requirements of Table 2 when tested in accordance with the vehicle impact test criteria.
