    32、5 Introduction In order to improve and maintain highway safety, the design of safer roads requires, on certain sections of road and at particular locations, the installation of road restraint systems. These road systems are designated to redirect errant vehicles with a specified performance level an

    33、d can provide guidance for pedestrians or other road users. This European Standard is a revision of EN 1317-1:1998. The standard identifies test methods and impact test acceptance criteria that the products for road restraint systems need to meet to demonstrate compliance with the requirements, give

    34、n in EN 1317-5 and/or prEN 1317-6. The design specification, for road restraint systems entered in the test report, identify important functional site conditions in respect of the test installation. The performance range of the products for road restraint systems, designated in this standard, enable

    35、s national and local authorities to recognize and specify the performance class to be deployed. Annexes A and B give informative explanation of the measurement of the severity index ASI and vehicle acceleration. BS EN 1317-1:2010EN 1317-1:2010 (E) 6 1 Scope This European Standard contains provisions

    36、 for the measurement of performance of products for the road restraint systems, under impact and impact severity levels, and includes: Test site data; Definitions for road restraint systems; Vehicle specification (including loading requirements) for vehicles used in the impact tests; Instrumentation

    37、 for the vehicles; Calculation procedures and methods of recording crash impact data including impact severity levels; VCDI. The modifications included in this standard are not a change of test criteria, in the sense of EN 1317-5:2007+A1:2008, ZA.3. 2 Normative references The following referenced do
