27、 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contra

28、ct 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 inspections set forth in this specification where s

29、uch 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 become a part of the contractors overall inspe

30、ction system or quality program. The absence of any inspection 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 inspecti

31、on, 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, nor does it commit the Government to accept defective material. 4.1.2 General Drovisions.

32、Unless otherwise specified herein, the provisions of MIL-A-48078 apply and form a part of this specification. Reference shall be made to MIL-STD-109 to define quality assurance terms used herein. 4.2 Classification of inspections. The inspection requirements specified herein are classified as follow

33、s: a. First article inspection (see 4.3). b. Quality conformance inspection (see 4.4). 4.3 First article inspection. 4.3.1 Submission. Prior to production, a sample shall be submitted in accordance with contract requirements and shall consist of 650 cartridges, 125 primed cases and 125 traced projec

34、tiles (see 6.3). The sample shall be manufactured using similar equipment, processes and procedures as will be used in production. Identification shall be in accordance with MIL-STD- 1168. 5 Licensed by Information Handling Services4.3.2 Inspections to be performed. The tests listed in Table I shall

35、 be performed on the first article sample in accordance with the test methods prescribed in 4.6. Except as otherwise specified, tests shall be conducted with samples at 20 k 10C. Approval will be based upon examination of the complete sample for visual and dimensional characteristics listed in 4.4.2

36、 and tests listed in Table I. 4.3.3 Rejection. If any assembly, component or test specimen fails to comply with any of the applicable requirements, the first article sample shall be rejected. The Government reserves the right to terminate inspection upon any failure of an assembly, component or test

37、 specimen to comply with any of the requirements. In the event of rejection, the Government reserves the right to require the contractor to take corrective action and submit a new First Article quantity. 6 Licensed by Information Handling ServicesMIL-C-7LL38 b L7L7BL 3LB I Cu 8 rl t w I ul rl CI1 Cu

The term “inspection lot“ is defined as a homogeneous collection of units of product from which a representative sample is drawn or

41、which is inspected 100 percent to determine conformance with applicable requirements. Units of product selected for inspection shall represent only the inspection lot from which they are drawn and shall not be con- strued to represent any prior or subsequent quantities presented for inspection. Homo

42、geneity shall be considered to exist pro- vided the inspection lot has been produced by one manufacturer, in one unchanged process, using the same materials and methods, in accordance with the same drawings, same drawing revisions, same specifications and same specification revisions. All material s

43、ubmitted for inspection in accordance with this speci- fication shall comply with the homogeneity criteria specified herein, regardless of the type of inspection procedure which is being applied to determine conformance with requirements. 4.4.1.2 m. A lot shall consist of: a. Cartridges loaded by on

44、e manufacturer, in one unchanged process, in accordance with the same drawings and drawing revisions, and the same specification and specification revision. b. Like parts and assemblies (cases; primers; projectiles; tracer and ignition systems) having one manufacturers symbol and one interfix number

45、. c. Propellant from one lot. 4.4.1.3 Lot identification. Each cartridge and each packed ammunition lot shall be identified in accordance with applicable drawings and MIL-STD-1168, supplemented as directed by the procuring activity. Each packed lot shall further be identified by a national stock num

46、ber assigned by the procuring activity. 4.4.2 Examinations and tests. a. Classification of characteristics. Quality conformance examinations and tests are specified in the following Classifi- cation of Characteristics paragraphs. The contractors quality program or detailed inspection system shall pr

47、ovide assurance of compliance of all characteristics with the applicable drawing and specification requirements utilizing as a minimum the conformance criteria specified. When cited herein, attributes sampling inspection shall be conducted in accordance with Table II, using the inspection levels sta

48、ted in the Classification of Characteristics paragraphs. 9 Licensed by Information Handling ServicesMIL-C-7LL38 77799Ob 1771784 O27 W MIL-C-71138 (AR) TABLE II. Attributes sample inspection.
