DIN EN 1317-3:2011-01 EN 1317-3:2010 (E) 5 Introduction Based on safety considerations, the design of roads may req

27、uire the installation of crash cushions at certain locations. These are designed to reduce the severity of vehicle impact with a more resistive object. The standard specifies the levels of performance, required of crash cushions, for the restraint and/or redirection of impacting vehicles. The impact

28、 severity of vehicles in collision with crash cushions is rated by the indices Theoretical Head Impact Velocity (THIV), and Acceleration Severity Index (ASI) (see EN 1317-1). The different performance levels will enable national and local authorities to specify the performance class of crash cushion

29、s. Attention is drawn to the fact that the acceptance of a crash cushion will require the successful completion of a series of vehicle impact tests (see Tables 1, 2, 3, etc.) as well as compliance with the full standard. DIN EN 1317-3:2011-01 EN 1317-3:2010 (E) 6 1 Scope This European Standard speci

30、fies requirements for the performance of crash cushions during vehicle impacts. It specifies performance classes and acceptance criteria for impact tests, which should be read in conjunction with EN 1317-1 and EN 1317-5. The modifications included in this European Standard are not a change of test c

31、riteria, in the sense of EN 1317-5:2007+A1:2008, ZA.3. 2 Normative references The following referenced documents are indispensable for the application of this document.
