The CPNI Vehicle Attack Delay Standard (VADS) provides a means for testing Vehicle Security Barriers (VSBs) against aggressive and repetitive vehicle impacts.
For organisations concerned with vehicle borne threats, including Vehicle as a Weapon attacks, VADS rated VSBs are not a substitute for IWA 14-1 and PAS 68 rated vehicle security barriers. VADS rated VSBs provide an alternative risk-based option for event managers and other risk owners: pragmatic, affordable and achievable levels protection, typically for, but not exclusively, temporary events.
For example, CPNI carried out VADS trials on some PAS68 and IWA14-1 VSB’s and found that they may be able to prevent a single impact by larger vehicles but struggled to prevent repetitive nudging and ramming attacks for an acceptable period of time. They subsequently wrote guidance on rising and swing arm vehicle security barriers.
The best practice and standards set out in existing CPNI guidance provides the highest level of protection and include the preferred deployment of temporary, semi-permanent and permanent VSBs.
CPNI strongly recommend that the deployment of vehicle security barriers should be based on thorough security Operational Requirements.
The deployment of VADS VSBs should only be done with a full understanding of their performance capability. This will inform the decision process for selecting suitable measures. The chosen VSB should provide the appropriate level of protection against the defined vehicle borne threat/s in order to reduce risk to an acceptable level.
The Vehicle Access Delay Standard (VADS) has been developed to allow the testing of barriers predominantly used at temporary events. Where CPNI assess there is a need the standard also accommodates the testing of permanent barriers, for example roller shutter doors.
CPNI strongly recommend the end user verifies claims that a VSB holds VADS approval by confirming its presence in this CSE VADS Chapter. In the first instance, for further advice regarding the products performance rating and characteristics please enquire with the manufacturer listed in the CSE. Additional advice can be sought from CPNI Sector Advisors, NaCTSO, Police Counter Terrorist Security Advisors, Members of the Register of Security Engineers and Specialists and Chartered Security Professionals.
End users are reminded that the VADS approval allocated to a VSB are based on specific layouts/configurations that were used in the testing. The listing in this CSE VADS Chapter will state the configurations that hold the VADS approval. Deviating from a rated configuration will incur risk. Using the check list in CPNI’s guidance: Due diligence in the selection and procurement of vehicle security barriers users should satisfy themselves that VSB will meet the specification.
VSBs not listed in this CSE Chapter have either not been tested to VADS or have not met the required performance level (i.e. failed). CPNI is the only body able to issue VADS approval and its decision is final. False claims can be reported to firstname.lastname@example.org.
Manufacturers of VSBs who believe they have a product that is robust enough to resist aggressive and repetitive vehicle impacts and wish it to be tested to the CPNI VADS should contact email@example.com. Initial submission should include a written description of the proposed product, images and details of all vehicle impact ratings the product has already received. CPNI will not accept products for VADS testing if they already have a PAS68 and / or IWA14-1 performance rating unless CPNI assess that particular product is vulnerable to a VADS style of attack.
Currently VADS testing is conducted at HORIBA MIRA in the UK when approval of the product to go forward for testing has been received from CPNI.
