A.3 DEFINITIONS
A.3.1 Complete penetration, (CP). A complete penetration occurs when the impacting
projectile, or any fragment thereof, or any fragment of the test specimen perforates the
witness plate, resulting in a crack or hole which permits light passage when a 60-watt,
110-volt bulb is placed proximate to the witness plate.
A.3.2 Fair impact. An impact may be considered fair when an un-yawed fragment
simulator or test projectile strikes an unsupported area of the target material at a specified
obliquity at a distance of at least two projectile diameters from any previous impact or
disturbed area resulting from an impact, or from any crack, or from any edge of the test
specimen.
