Prior to regular production, a sample shall be submitted in accordance with contract requirements and shall consist of 914 cartridges, 125 primed cases, and 125 projectiles (see 6.3)?. The sample shall be manufactured using

28、 equipment, processes, and procedures that are similar to those used in regular production. Identification shall be in accoidance with MIL-STD-1168. 4.4.1.1 Examination and test. The tests of Table I shall be performed on the first article sample in accordance with the test methods prescribed in 4.6

29、. Except as otherwise specified herein, the tests shall be conducted with samples at 20 +lOC. Approval shall be based upon eximination of the complete sample for visual and dimensional characteristics listed in 4.5.3 and the tests of Table I. The combining of tests shall be permitted provided that t
