CBRNe World and Cranfield University collaborate on new explosive detector testing service
CBRNe World has joined forces with Cranfield University to provide independent lab and field testing of explosive detection systems.
The tests, which can be adapted for both pre- and post-blast detectors, independently test detectors to ASTM standard practice for verifying the minimum, acceptable performance level of trace explosive detectors (E2520 – 07 Standard Practice for verifying Minimum Acceptable Performance of Trace Explosive Detectors). Our aim is to allow companies to independently verify the performance of their trace explosive detection equipment, and provide reports that can be openly distributed by them.
The principle test package uses TNT, RDX and PETN in accordance with ASTM requirements, however a number of other explosives are available for testing, including AN, TATP and HMEs.
Systems will be tested in accordance with the ASTM Standard practice for verifying minimum acceptable performance of trace explosive detectors. The system will be deemed to have passed if it successfully detects and identifies (if capable) all positive samples, returns a negative result for all blank control swabs and either identifies or gives a negative result for the interferent tests.
A series of controlled explosions will be carried out, generating soil and a range of material samples for testing. Samples will be split and contamination verified by Cranfield Labs. The system will be deemed to have passed if the explosive contamination is detected and identified (if capable) in positive samples, returns a negative result for all blank control swabs and either identifies or gives a negative result for the interferent tests.
Unlike many other explosive detector tests, the results can be shared with major institutes such as the DHS, NIST, Home Office, MoD and DSTL. Equally, the results can be kept confidential. The service also provides scenario-based tests that can be designed to suit a manufacturer’s requirements, as well as customer demonstrations, high-speed/thermal video footage and photo’s.
This new detection testing service is the brain child of Steve Johnson, who said, “Getting to the heart of explosive detection standards means running equipment through realistic, standardised scenarios in the lab and on the range. CBRNe World is proud to be collaborating with Cranfield University to deliver this as commercial testing, but also as part of a wider research programme that CBRNe World has been supporting for the last year”.
