NBN EN 1317-2/A1:2006

This 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 methods. The 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 equipment.
