Crash Tested Products – PAS 68; IWA; CWA

The Cova PAS 68:2010 compliant crash rated security gate range has been specifically developed to counter Vehicle Borne Improvised Explosive Devices (VBIED) to critical national infrastructure, as well as protect other high profile sites and businesses.

Cova crash tested PAS:68 compliant range covers a diverse range of our products including bi-folding speed gates, sliding cantilevered gates, shallow depth road blockers, full depth road blockers, static bollards, rising bollards and barriers.

Our crash tested products can withstand impact speeds of 30mph, 40mph and 50mph from a 7.5 tonne vehicle.


BSi PAS 68 stands for Publicly Available Specification (PAS) for vehicle security barriers. It has been the UK’s standard and recognised security industry’s standard for HVM (Hostile Vehicle Mitigation) equipment. It is the benchmark in which perimeter security equipment is tested as part of the ongoing research to prevent VBIED (Vehicle Born Improvised Explosive Device) attacks.

PAS68 explained

For Example = V/7500(N2)/48/90:2.4/7.9
V= Impact test – Actual vehicle impact tested to repeatable scientific conditions

1500, 2500, 3500, 7500= mass of vehicle ie. weight in kg

N1: Vehicles designed and constructed for the carriage of goods and having a maximum mass not exceeding 3,5 tonnes.
N2: Vehicles designed and constructed for the carriage of goods and having a maximum mass exceeding 3,5 tonnes but not exceeding 12 tonnes.
N3: Vehicles designed and constructed for the carriage of goods and having a maximum mass exceeding 12 tonnes.

48 = speed in KPH (30mph) Vehicle impact test speed of the test vehicle measured along its approach path at a point no further than 8m before the impact point.
64 = speed in KPH (40mph)
80 = speed in KPH (50mph)
90= Impact angle of test in the horizontal plane, between the intended impact face and the approach path of the test vehicle into the test item. Usually 90 degrees although some tests are at 45 degrees such as fencing

2.4 = In pas 68 this is the penetration of the vehicle is measured from the original position of the REAR face of the equipment

7.9 = where major debris landed beyond the original position of the rear face of the equipment.

IWA 14 : 2013

IWA (International Working Agreement) purely measures vehicle impact performance and not the surrounding site environment like PAS 68 (or PAS 69) does.

CWA 16621 : 2010

A European Workshop Agreement that combines elements from BSI PAS 68 and PAS 69. It advises on test methods for determining vehicle security performance and product selection and installation.
