All parts and materials, including packaging and packing, shall be the same as used for regular production and shall be obtained fr
28、om the same source of siipply. When it becomes necessary to make a change in either the primer, propellant, or igniter lot after initial production, 12 assembled cartridges from the first production lot thereafter shall be tested in accordance with 4.7.7. The Government reserves the right to require
29、 new first article samples until such time as an acceptable sample is submitted (see 6.3). 4.4.1 Examination, tests, and facility. After provisional acceptance at source, the sample shall be inspected for all requirements of the drawings and specifications at a Government laboratory or other such fa
