CWA 16221:2010

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).
