Essential Reading
Security Equipment listed in this CSE Chapter has been allocated a rating in accordance with NPSA’s Vehicle Attack Delay Standard (VADS).
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.
The best practice and standards set out in existing NPSA guidance provides the highest level of protection and include the preferred deployment of permanent and semi-permanent IWA14-1 and PAS68 rated VSBs.
NPSA 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 Attack Delay Standard (VADS) has been developed to allow the testing of barriers predominantly used at temporary events. Where NPSA assess there is a need the standard also accommodates the testing of permanent barriers, for example roller shutter doors.
NPSA strongly recommend the end user verifies claims that a VSB holds VADS approval by confirming its presence in this CSE 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 NPSA 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 Chapter will state the configurations that hold the VADS approval. Deviating from a rated configuration will incur risk. Using the check list in NPSA’s guidance: Due diligence in the selection and procurement of vehicle security barriers, users should 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). NPSA is the only body able to issue VADS approval and its decision is final. False claims can be reported to [email protected].
NPSA wishes to thank all the companies, including those whose products did not pass the testing, for stepping up to the challenge and responding to our testing calling notice.
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 NPSA VADS should contact [email protected]. Initial submission should include a written description of the proposed product, images and details of all vehicle impact ratings the product has already received. NPSA will not accept products for VADS testing if they already have a PAS68 and / or IWA14.1 performance rating unless we assess that particular product is vulnerable to a VADS style of attack.
