1 WHITEPAPER The New International Workshop Agreement (IWA ) Standard Introduced & Explained

2 1.1: Regional Impact Test Standards: CWA ASTM (Previously DOS) PAS 68 & 69 Standard Region of Origin Year of Origin ASTM USA 2007 CWA Europe PAS 68 & 69 UK : Overview of the different impact test standards: PAS 68 & 69 The PAS 68 & 69 standard was originally drawn up in 2005, the first UK impact test standard. The output from the standard is an impact classification describing the test type, impact test mass, vehicle type, impact angle, vehicle penetration distance and debris spread. This classification code is very descriptive and aimed to explain exactly how a vehicle barrier/bollard would behave under attack. Example: Auto Bollard V/ /7500(N2)/64/90:0.53/6.10 Product Type Test Speed (kph) Penetration (m) Test Method V (vehicle) Vehicle Mass (Kg and type) Impact angle ( ) Dispersion Distance of Major Debris PAS 68 refers directly to the impact test itself and PAS 69 concentrates on the installation of high security equipment and the considerations which need to reviewed before selecting a product to protect critical national infrastructure (0)

3 ASTM Originating in 2007, the American ASTM standard superseded the previous DOS standard. The scope within this standard changed at it was widely recognised that the original DOS standard needed further development to encompass further information regarding penetration levels and vehicle types. The original DOS certification provided no more information than a tested product had either passed or failed an impact test which then was further elaborated to L1-L3 which alluded to penetration levels achieved. The new ASTM derivative provided even more detail and accredited a product with a P classification and vehicle differential which equated to the below: Designation Dynamic Penetration P1 Less than 3.3ft P2 3.3ft to 23 ft P3 23ft to 98ft P4 98ft or greater

4 CWA A European impact test certification originating in 2010 which amalgamates both the PAS 68 & PAS 69 standard. This standard provides guidance on test methods for determining the vehicle security barrier performance classification and also includes a series of informative annexes that advise on appropriate product selection, installation and use. The standard was written to address the needs of organisations who wanted to have assurance that vehicle security barriers will provide the level of impact resistance sought. Not only did the standard aim to identify impact test methods, test vehicle type and performance criteria; CWA also provided guidance on the selection, installation and use of vehicle security barriers to ensure that products are selected and installed as effectively as possible. This CWA was intended to be used by designers, planners, architects, security managers and facilities managers within the public and private sectors. 2.1: The New International Workshop Agreement Introduced & Explained: The new impact test standard is the International Workshop Agreement 2014 (IWA). This standard aims to unify both American (ASTM) and UK (PAS 68 & 69) impact test standards. Utilising the PAS 68 test criteria, one of the fundamental changes to previous specifications is the new reference point for penetration. Point 2 on the above diagram demonstrates the new reference point. IWA 14 KEY: 1. Barrier/Bollard 2. Barrier/Bollard Datum Line 3. Vehicle Datum Point 4. Vehicle Penetration Distance 5. Major Debris 6. Major Debris Distance

5 PAS 68 KEY: 1. Barrier/Bollard 2. Rear Face of Barrier/Bollard System, Datum Line 3. Vehicle intersection of base of windscreen and A pillar/leading edge of vehicle load platform. 4. Vehicle Penetration Distance 5. Major Debris 6. Major Debris Distance The IWA 14 standard measures impact penetration from the front of the barrier/bollard (the impact face) and PAS 68 measures penetration from the rear of the barrier/bollard. Some implications when considering this change: Measuring impact in this way will make the penetration comparisons between road blockers (flat and wide structures) and bollards (tall and thin structures) more accurate. The standard aims to unify existing certifications, taking into consideration a wide range of international test vehicles. This will remove the ASTM Vs. PAS 68 argument, internationalising the impact test standard. See the new standard classification in the below table:

6 2.2: Other Points to Note When Reviewing the IWA 14 Standard No development test method or engineered solution is currently allowed under the new standard. This means that any slight product variations will still have to be accredited under the previous PAS 68 standard. No guidance documents are supplied with the standard as with previous certifications. The IWA 14 purely concentrates on the impact test and not the surrounding site environment or site assessment criteria needed for Counter Terrorism Measure (see below items covered in the UK PAS 69): This new standard will not grandfather previous product tests and will not negate the ASTM, CWA or PAS 68 & 69 standard. It purely aims to internationalise and amalgamate previous standards to produce a test specification which can be recognised and advertised internationally as the future of HVM certification.
