Hostile Vehicle Mitigation Products
There are various independent testing regimes that can be applied to perimeter security products. Further information on a number of these regimes is given below.

PSSA Verification Scheme
In 2011 the PSSA introduced a verification scheme to provide confidence to perimeter systems buyers and others that products supplied by its members conform to internationally recognised quality standards, providing assurance that:
- products are fit for purpose – designed to meet customer, market and regulatory requirements
- products are consistently manufactured and supplied conforming to their agreed specification
- products when in use produce the intended performance outcomes specified by the customer
Following a rigorous process of evaluation of both a supplier’s management system and verification of the product, authority to use the PSSA Verification Mark is given and the product publically listed on the Verification Scheme section of our website.
The Centre for the Protection of National Infrastructure (CPNI)
The CPNI is a UK governmental organisation that protects national security by providing protective security advice to key infrastructure sectors. It holds a list of products that it has had independently tested. Manufacturers of such products are allowed to say whether or not a particular product is approved by CPNI but they are not allowed to divulge detailed information about the test method or the test result. Organisations or individuals requiring such information must contact CPNI direct.
The Loss Prevention Certification Board (LPCB) – LPS1175
LPS 1175 covers the broadest scope of physical security products and services of any publicly available standard in the world. LPS 1175 is the result of many years of work by the Loss Prevention Certification Board (LPCB), Government, Insurers and Police, and has rapidly become a core element of physical security specification across many sectors. The standard comprises a number of security ratings with test requirements of ascending intensity (SR1, SR2, etc. the higher the number, the greater the resistance to attack). These are measured in terms of attack tools and time available to the attacker, and enables specifiers to select products according to the risks that they and their property face. LPS 1175 can be used in a range of applications, from residential right through to critical infrastructure projects.
Secured by Design (SBD)
Secured by Design (SBD) is the UK Police flagship initiative supporting the principals of “designing out crime” by means of effective crime prevention. Products that are awarded SBD approved status have passed a thorough, strict, and independent testing programme.
BSI PAS 68
BSi PAS 68 is the best known Publicly Available Specification (PAS) for vehicle security barriers. In recent years it has been 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.
PAS68 classification code 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= 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.

ISO IWA 14-1 2013
IWA 14-1 is a relatively new International ISO agreement. It combines and updates elements from PAS68, PAS69, ASTMF and CWA16221. IWA specifies the essential impact performance requirement for a vehicle safety barrier (VSB) and a tested method for rating its performance when subject to a single impact by a test vehicle not being driven by a human being.
IWA 14 Classification Code
For Example = V/7200(N2A)/64/90:6.9
V= Impact test – Actual vehicle impact tested to repeatable scientific conditions
Type of product
7200= weight in kg
N2A Vehicle is 7.5 Tonne European specification type vehicle
N2B Vehicle is 7.5 Tonne American specification type vehicle.
64 = speed in KPH AS ABOVE
90= Impact angle of test usually 90 degrees although some tests are at 45 degrees such as fencing
6.9 = In IWA 1400 the penetration is measured from the FRONT face of the equipment the VSB datum line

In the new IWA 14 Standard Measuring penetration in this way will make the comparisons between road blockers (flat and wide structures) and Bollards (tall and thin structures) tests more accurate
