This CWA specifies a classification system for the performance of a vehicle security barrier (VSB) when
subjected to a single horizontal impact.
This CWA specifies two methods for determining the performance classification of a VSB:
the vehicle impact method for all types of VSBs using a test vehicle classified in accordance with EC
Directive 2007/46/EC [1] and registered for use in Europe;
the design method for all types of VSBs.
This CWA refers to alternative test methods for determining the performance classification of a VSB (see
Annex A).
This CWA also provides guidance for the selection, installation and use of VSBs (see Annexes D to M).
This CWA also describes the process of producing “operational requirements” (see Annex N).
This CWA does not cover the performance of a VSB or its control apparatus when subjected to:
blast explosion;
ballistic impact;
manual attack, with the aid of tools (excluding vehicles).
