article description
This article discusses experimental results from blast testing of Security Devices Ltd. polycarbonate visors used by humanitarian deminers. Visors used in the blast testing fell into one of three categories: new visors, manually scratched visors, and scratched and heat-gun-repaired visors. Results show that the visors in all three categories failed to meet the draft international standard for blast testing relevant at the time, that further research is required to establish pressure profiles for the standard charge size being tested, and that the proposed heat- treatment method does appear to degrade the blast resistance of the visor used in the test.
