At the beginning of regular production, the contractor shall submit a first article sample to a Government approved facility for evaluation. The sample shall consist of 21 assembled cart
35、ridges for ballistics testing including 12 for vibration tests, 5 assembled cartridges for sealant tests, 10 sets of unassembled components for dimensional and visual examination, and the quantity specified in accordance with 4.4.2, i.e., cartridges assembled without the igniter and propellant charg
36、e for ignition device sensitivity test. The first article sample shall be manufactured using the same materials, equipment, processes, and procedures as used in regular production. All parts and materials, including packaging and packing, shall be the same as used for regular production and shall be
37、 obtained from the same source of supply. When it becomes necessary to make a change in either the ignition device, 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
