Requisite NZ Ltd can offer advice on physical ballistic resistance and can also manufacture, supply and install all the ballistic-resistant products that are needed in accordance with the applicable specifications. If you wish, they can also be offered in combination with intruder, blast and fire resistant properties.
The Australia and New Zealand common standard AS / NZS 2343 requires three shots per sample and is therefore a more vigorous test. The USA standard – NIJ 0108.1 requires five shots per sample. Internationally, test standards NIJ 0108.1 and UL752 are probably the most widely accepted.

Most ballistic test standards require a ‘witness card’ made of a thin material that is positioned closely behind the test item, and ANY perforation of it constitutes a failure.
