Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinati

26、ons and tests) as specified herein. 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

27、right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements (see 6.2). 4 e Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-1 t-

The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any in

29、spection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an accepta

30、ble practice to ascertain conformance to requirements; however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.1.2 Quality assurance terms and definitions. Reference shall be made to MIL-ST

31、D-109 to defme the quality assurance terms used. 4.1.3 Inspections. Inspections shall be in accordance with MIL-A-2550 and MIL-STD-453. 4.2 Classification of inspections. The inspection requirements specified herein are classified as follows: a. First article inspection (see 4.4) b. Quality conforma

32、nce inspection (see 4.5) 4.3 Inspection conditions. Unless otherwise specified in the contract or purchase order (see 6.2), inspection conditions shall be as follows: a. Temperature: Room ambient 20“ to 25“ C (68“ to 77“ F) b. Altitude: Sea level c. Humidity: 50 percent relative, maximum d. Atmosphe

33、ric: 14.7 psia 4.4 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 21 assembled cartridges for ballistics testing including 12 for vibration tests, 5 ass

34、embled cartridges for sealant tests, 10 sets of unassembled components for dimensional and visual examination, and the quantity specified in accordance with 4.4.2, Le., cartridges assembled without the igniter and propellant charge for primer sensitivity test. The first article sample shall be manuf

35、actured 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 obtained from the same source of supply. When it becomes necessary to make a c

36、hange 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 new first article samples until such time as an acceptable sample i

37、s 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 facility specified in the contract (see 6.2). 5 Provided by IHSNot for
