PAS 68:2007

PAS 68:2007 has been prepared to address the needs of organizations who wish to have assurance that vehicle security barriers will provide the level of impact resistance that they seek.

Many systems are available that are either promoted or considered suitable for use as vehicle security barriers. As their characteristics differ in both function and form, a comparative means of assessing their performance is required.

PAS 68:2007 specifies a classification system for the performance of vehicle security barriers and their supporting foundations when subjected to a single horizontal impact.

In the course of this document three alternative assessment methods of determining the performance classification of vehicle security barriers are given:

• The vehicle impact method
• The pendulum method (only suitable for testing bollards at lower energy levels)
• The design method.

This PAS identifies impact test tolerances and vehicle performance criteria that need to be met in order to conform to it. Design guidance is provided in PAS 69:2006.
