What is PAS 68?

BSi PAS 68 is the latest Publicly Available Specification for vehicle security barriers. It has become the UK’s standard and the security industry’s benchmark for HVM (Hostile Vehicle Mitigation) equipment, and is the specification against which perimeter security equipment is tested as part of the ongoing research to prevent VBIED (Vehicle Born Improvised Explosive Device) attacks. BSi PAS 69 complements this specification by providing guidance on the product installation.

BSi PAS68 Specification

PAS 68: 2013 specifies a classification system for the performance of vehicle security barriers, subjected to a single horizontal impact.

PAS 68: 2013 identifies impact test tolerances and vehicle performance criteria which need to be met in order for a product to conform and be granted a classification.

Design guidance is provided in PAS 69:2013.
BSi PAS 69:2013 should be considered to ensure this equipment is installed correctly.

The PAS68 specification defines the vehicle type, test mass and impact speed together with the required measurements, vehicle and test item details that should be recorded and reported. Post impact, and if the test is successful -the VSB stopped and immobilised the test vehicle, then the penetration distance is measured. This reading is taken from the front of the vehicle cargo load bed to the position of the original rear face of the VSB. The dispersion distance of major debris is also measured as this may be a consideration at certain sites. 
These measurements can be used to determine which is the most suitable VSB for each individual site. It must be remembered that the impact testing uses repeatable test criteria and may not replicate the precise dynamics of real life attacks or vehicle configurations. However, it does provide a common baseline to classify and compare VSB systems. Equipment that has been tested in accordance to the BSi PAS68 specification requires an appropriate installation which is tailored to the individual sites ground and environmental conditions. This ensures the adequate performance if challenged in a hostile vehicle attack.

The importance of after sales and who should maintain your equipment is another aspect which should be considered. 

Foundation Classifications

The VSB system foundation shall be classified according to the following

Classification                           Description

A                                             Freestanding' having no ground fixing

Ap                                           Surface mounted but also pinned or bolted to the ground

B                                             Depth <0.5m below ground level

C                                             Depth >0.5m below ground level
