Abstract : The U.S. Army Defense Ammunition Center and School (USADACS), Validation Engineering Division (SIOAC-DEV), was tasked by USADACS, Maintenance Engineering Division (SIOAC-DEM), to retest the ammunition peculiar equipment (APE) 1955 grenade fuze tester for shrapnel retention as defined in MIL-STD-398, Military Standard, Shields, Operational for Ammunition Operations, Criteria for Design of and Tests for Acceptance; Method 201, Fragment Retention Test. This test was required to certify an engineering design change of the cleanout door assembly. The original design consisted of a concentric rotational door that covered the cleanout port where grenade fuzes were being tested. Tolerances between the rotational cleanout door and the drop table are specified at 1/64-inch. This size tolerance trapped frequent residue between the drop table and cleanout door, preventing the cleanout door from being easily opened for cleaning. As a result of the difficulty in opening the cleanout door, it was redesigned as a hinged door to alleviate blast fragments from jamming the cleanout door. Since this is the only structural change to the original APE 1955 grenade fuze tester, only the frequent retention test of MIL-STD-398 was required. As a result of the difficulty in opening the cleanout door, it was redesigned as a hinged door to alleviate blast fragments from jamming the cleanout door. Since this is the only structural change to the original APE 1955 grenade fuze tester, only the frequent retention test of MIL-STD)-3 98 was required.
