Hostile Vehicle Mitigation

HVM

Hostile Vehicle Mitigation considers the threat from hostile vehicles and reduces the threat through planned and considered design thereby reducing the overall risk in any given situation. Typically, the HVM process starts with a Dynamic Vehicle Assessment, real-time public space analysis and an understanding of the likelihood of attack. Townscape has been providing HVM consultancy and products for over 47 years and would be pleased to discuss the options for assessment for your project.

PAS 68 / IWA 14 TEST STANDARDS

Townscape first tested to PAS 68 in 2003. The standard is still considered the gold standard for crash tested product. The Publicly available standard measures performance criteria during a real time crash situation carefully undertaken by a proprietary  UKAS laboratory.
In the U.K this tends to be TRL or more recently HORIBA MIRA. IWA 14 is an international standard designed to update and harmonise standards through a CEN Workshop Agreement. PAS 68, PAS 69 and the North American ASTM F2656 standard have been added into in IWA 14/1 and IWA 14/2.

ISO 22343-1:2023 TESTING INFORMATION

ISO 22343-1:2023 – Performance Requirement, Vehicle Impact Test Method, and Performance Rating

The standard outlines the impact performance requirements for VSBs and specifies a standardized test method to assess their effectiveness against a single impact from an unmanned test vehicle. Key changes from previous standards include updated vehicle classifications reflecting the evolving vehicle landscape by introducing new classifications and mass types. Additionally performance criteria has been updated and defined as impact test tolerances and vehicle performance criteria necessary for a product to achieve a classification. The testing  landscape has also been further clarified to include vehicle penetration distances do not exceed 25 meters and focusing on single horizontal impacts. The standard is intended for manufacturers and procurers of VSBs used to protect people in public or private locations from vehicle attacks.

ISO 22343-2:2023 – Application
Part 2 provides guidance on the selection, installation, and use of VSBs, and describes the process of producing Operational Requirements (ORs). It  offers a design method for assessing VSB performance, considering factors like vehicle type, mass, speed, geographical application, and site location. Exclusions: Specifies that the standard does not apply to VSB performance under conditions such as slow-speed encroachment, blast explosions, ballistic impacts, manual attacks, or electrical manipulation. This part is applicable to end users, such as site owners and specifiers, where VSBs are used to protect people in any public or private location from vehicle attacks.

Together, ISO 22343-1 and ISO 22343-2 provide a unified and internationally recognized approach to the testing and application of vehicle security barriers, enhancing the effectiveness of hostile vehicle mitigation strategies.

PERFORMANCE TESTING

Most HVM is concerned with 1500kg – 7500kg vehicle weights with a scenario of a vehicle borne attack. Most dynamic vehicle assessments consider vehicle speeds of 20,30,40 and 50 mph with a range of attack vectors.
Additional  testing is also underway considering street furniture effectiveness against vehicle as a weapon scenarios. For additional information about Vehicle Attack Delay (VADs) and or temporary event protection please contact your local Townscape Technical Consultant who can provide addition assistance in this area.
