Except as otherwise specified in the contract or order, the supplier may use his own or any other facilities suitable for the pe
18、rformance 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 the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requir
19、ements. Reference shall be made to Standard MIL-STD-109 in order to define terms used herein. The provisions of Specification MIL- A-2550 shall apply. 4.1.1 Submission of product.-At the time the completed lot of product is submitted to the Government for acceptance, the contractor shall supply the

24、lot“ as used throughout this specification refers to an inspection lot, which is defined as an essentially homogeneous collection of units of product from which a representative sample is drawn and inspected to determine conformance of the lot with applicable requirements. The sample selected shall
25、represent only that quantity of units from which the sample was drawn and shall not be construed to represent any prior or subsequent quantities presented for inspection. Homogeneity shall be considered to exist provided the lot has been produced by one manufacturer in one unchanged process, in acco
26、rdance with the same drawings, same drawing 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-C-14747 (MU) revisions, same specifications and same specification revisions. Changes to the process, specification, or drawings not affecting safety, p
27、erformance, interchangeability, or storage, as determined by the Government, shall not be deemed to alter the homogeneity of the lot. Inspection lots shall comply with MIL-STD-105. Unless otherwise approved by the contracting officer, the inspection lot size of end items deliverable under the contra
28、ct shall be not less than the smallest weekly estimate of quantities contractually scheduled for production during the contract period nor more than the largest monthly quantity contractually scheduled for delivery during the contract period. lots of components or subassemblies, other than the items
29、 of delivery, shall be homogeneous and of a size mutually con- venient to both the contractor and the Government inspector. Lot numbering, as required, shall be in accordance with MIL- STD-1168.

Sampling plans and procedures for Major and Minor defects shall be in accordance with MIL-STD-105 except that continuous sampling plans in accordance with MIL-STD-1235 may be used if approved by the procuring activity. Also, at the option of th
33、e procuring activity, AQLs and sampling plans may be applied to individual characteristics listed using an AQL of 0.65 percent for each Minor defect and an AQL of 0.40 percent for each Major defect, except where 100 percent inspection is specified.
