3.4 Ballistic requirements. The minimum protection ballistic limits (BL(P)) of the test plate
shall be in accordance with the values shown in Tables 3 through 8. No through cracks greater
than 2.5 inch in length on any plate surface are permitted after ballistic testing. When a
complete penetration can not be obtained for any class of armor material, the following rule
shall be in effect until a new ballistic acceptance round can be developed and utilized. When
the ballistic velocities of four (4) partial penetrations are above the minimum ballistic
requirement for the specific thickness, the material shall be certified as acceptable with a V50
(which obviously can not be explicitly determined) above the minimum requirement.
