Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspe
33、ctions set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall
34、become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that ail products or supplies submitted to the Government for acceptance comply with ail r
35、equirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements, however, this does not authorize submission of known defective material, either indicated or actual, not does it commit the Government to accept
36、defective material. O 4.2 Lots. 4.2.1 First article inspection. 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 95 assembled cartridges and shall undergo the tests listed in table
37、 II, including 12 for vibration tests (to be selected from ballistic samples) and 10 sets of unassembled components for dimensional and visual examination. The sequence of testing and division of test samples shall be as indicated in table III. The first article sample shall be manufactured using th
38、e 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 obtained from the same source of supply. When it becomes necessary to make a change in either
39、the primer, propellant, or igniter lot after initial production, 12 assembled cartridges from the first production lot thereafter shall be tested in accordance with 4.5.9. The Government reserves the right to require new first article samples until such time as an acceptable sample is submitted (see
40、 6.4). 5 Licensed by Information Handling ServicesflIL-C-38983A 13 9999906 O575797 O Test Materials MIL-C-38983A TABLE II. First article and lot acceDtance tests.
