41、EN 1317-2:2011-01 EN 1317-2:2010 (E) 6 Introduction This European Standard is a revision of EN 1317-2:1998. This standard includes improved impact test procedures and allows for the introduction of Families of Products and a report template. In order to improve safety the design of roads may require

42、 the installation of safety barriers including vehicle parapets which are intended to contain 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. In this standard, several levels of

43、 performance are given for the three main criteria relating to the restraint of a road vehicle: The containment level; The impact severity levels; The deformation as expressed by the working width and vehicle intrusion (including normalised values). The different performance levels of safety barrier

44、s including vehicle parapets will enable national and local authorities to specify the performance class of the system to be deployed. The description of a safety barrier including vehicle parapet system conforming to this standard incorporates the relevant classes and performance levels of the prod

45、uct. To ensure satisfactory product design it is highly recommended to consider the requirements of this standard and the references in Clause 2, together with the requirements of EN 1317-1. The evaluation of conformity and the durability should meet the requirements of EN 1317-5. DIN EN 1317-2:2011

46、-01 EN 1317-2:2010 (E) 7 1 Scope This European Standard specifies requirements on impact performance of safety barriers, including vehicle parapets, classes of containment, working width, vehicle intrusion and impact severity levels. NOTE This European Standard should be read in conjunction with EN

47、1317-1. Both these standards support EN 1317-5. The modifications included in standard are not a change of test criteria, in the sense of the EN 1317-5:2007+A1:2008, ZA.3. 2 Normative references The following referenced documents are indispensable for the application of this document.
