MIL-STD-662F, MILITARY STANDARD: V50 BALLISTIC TEST FOR ARMOR (18 DEC 1997)., The purpose of this standard is to provide general guidelines for procedures, equipment, physical conditions, and terminology for determining the ballistic resistance of metallic, nonmetallic and composite armor against small arms projectiles. The ballistic test procedure described in this standard determines the V50 ballistic limit of armor. This test method standard is intended for use in ballistic acceptance testing of armor and for the research and development of new armor materials. This ballistic test method is applicable to the following types of armor: a. Body armor. b. Armored seats for aircraft and ground vehicles. c. Crew station armor for military aircraft. d. Internal and external armor for aircraft. e. Transparent armor, such as windows, windshields and vision blocks for aircraft and ground vehicles. f. Bulkhead armor for shipboard use. g. Structural or integral armor for use on ship exteriors. h. Armor for military tactical shelters (AFWAL-TR-82-4163). i. Visors for eye and face protection. j. Armor for potential space applications. k. Armor for light and heavy combat vehicles and structures.
