    For security professionals and those tasked with specifying physical security products for the purpose of Hostile Vehicle Mitigation (HVM), IWA 14-1 and PAS 68 will no doubt be very familiar when considering the impact testing of physical security products.

    However, as of September 2023, with the publication of ISO 22343 by the British Standards Institution (BSI), both IWA 14 and PAS 68 have been replaced. ISO 22343 is now the current standard which defines the methodology by which vehicle security barriers, including bollards, barriers and road blockers are performance tested against vehicle impact.

    The results of tests carried out on specific products in accordance with ISO 22343, provides end users with a standardised format of test results. This provides manufacturers with a certified product to take to market (assuming the product passes the test) and also provides end users with a means to compare the efficacy of HVM products regardless of the manufacturer.

    Both IWA 14 and PAS 68 are replaced by ISO 22343, although there is no expectation or requirement on manufacturers to retest previously certified products to ISO 22343. Equally, existing products tested to IWA 14 and PAS 68 are still considered valid.

    With the release of ISO 22343, the experts here at ATG Access have updated our popular ‘Guide to Physical Security Standards eBook’ to include details on the new standard.

    The latest edition of the guide explains the differences between the old and current standards and goes through an example test result step-by-step to help you understand the new standard.


    Why is there a new standard?

    To know why this new standard has come into being, it’s perhaps useful to look back and understand the history of preceding standards and specifications.

    From their inception, the standards for measuring impact tests of hostile vehicle mitigation products have been somewhat fragmented geographically. The earliest standards were introduced by the American Department of Defense (DoD) to certify products that could protect overseas US assets, like Embassies and military bases.

    Due to the niche requirements that the DOD placed on this testing methodology, the initial standard was unable to be easily adapted to changing circumstances for commercial interests. Following the market’s desire for a rigid, yet attainable standard, this led to PAS 68 being introduced by the British Standards Institution in 2005.

    Similarly, ASTM 2656 (American Society for Testing and Materials standard for vehicle security barriers) was made available and adopted largely in American markets and followed more closely to the original DoD standards although with commercial interests in mind.

    IWA 14-1 followed in 2013, attempting in some respects to take learnings from PAS 68 and ASTM 2656 to create a new truly international and harmonised standard.

    ISO 22343 now replaces IWA 14-1 and PAS 68 as the current international standard.


    The Changes in ISO 22343

    ISO 22343 is similar in many respects to PAS 68 and IWA 14-1 but there have been modifications creating subtle nuances between them.

    The main changes include:

    • Vehicle classification descriptions
    • Additional vehicle mass classification type
    • Fail conditions for excessive vehicular penetration
    • Fail conditions for vehicles that are still mobile post impact
    • Additional vehicle age range available to be tested
    • Dispersed debris weight reduced from 25kg to 2kg

    Further details on the changes within ISO 22343are available in our ‘Guide to Physical Security Standards ebook’.  

    While the preceding standards and specifications appear similar on the surface, the changes are sufficient to require appropriate evaluation by a knowledgeable individual, to ensure that the choice of product for a given site situation is appropriate.

    Given that HVM (Hostile Vehicle Mitigation) products exist to protect assets, infrastructure, and ultimately human lives, consulting an organisation or individual with the necessary expertise to navigate the standards on your behalf is always our recommendation.
