(Adapted from Terminology E3005.)4. Summary of Test Method4.1

24、 The ballistic resistance of a product or shoot pack isdetermined by firing a series of test threats at each of a set oftest items and assessing the number of partial penetrations andcomplete penetrations.4.2 The performance requirements and test threats shall bespecified in other standards and spec

25、ifications.NOTE 2The performance requirements may be defined in terms ofeither: (1) The number of required fair hit impacts and the allowablenumber of complete penetrations, (2) The minimal acceptable calculatedprobability of a single impact being stopped and a correspondingconfidence level. In this

26、 case, a minimum number of required fair hits mayalso be set, or (3) A combination of the above.5.
