PAS 68 Impact test specifications for vehicle security barriers

This Publicly Available Specification (PAS) has been prepared to address the needs of organizations who want assurance that vehicle security barriers will provide the level of impact resistance they are aiming for.

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 identifies impact test methods, tolerances, test vehicle type and vehicle performance criteria that need to be met in order to conform to PAS 68. Design guidance for installing barriers is provided in PAS 69:2006.

PAS68 cites a classification system for the performance of vehicle security barriers and their supporting foundations when subjected to a single horizontal impact.

This PAS specifies two test methods of determining the performance classification of vehicle security barriers:

• The vehicle impact method
• The design method [which includes the use of finite element analysis (FEA) techniques if validated by test data].

This PAS lists alternative test methods for determining the performance classification of a vehicle security barrier.

This PAS does not cover the performance of a vehicle security barrier when subjected to blast or ballistic impact.
