21、 contracting officer for evaluation in accordance with the provisions of 4.2.2 and 4.2.3. The first article sample shall consist of 50 complete sets of parts and sub-assemblies (i.e. 50 each of every component and sub-assembly, which have been produced by the contractor or furnished by a supplier an

The sample selected shall 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 inspection lot has be
30、en 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 and complies with the provisions for submission of product as specified in MIL-STD-105. Cha
31、nges to the process, specifications, or drawings not affecting safety, performance, interchangeability or storage, as determined by the Government, shall not be deemed to alter the homogeneity of an inspection lot. All material submitted for inspection in accordance with this specification shall com
32、ply with the homogeneity criteria specified herein regardless of the type of sampling procedure which is being applied to determine conformance with requirements. Lot numbering, as required, shall be in accordance with MIL-STD-1168. Each inspection lot of loaded detonator assemblies shall contain: a
33、. Parts from one lot interfix number from one b. Primer mixture from one batch or blending of batches c. Lead azide of the same type from not more than two manufacturer. which results in homogeneity of all primer mixtures used in loading the entire detonator lot. lots produced by the same manufactur
34、er in accordance with the same specification and same specification revision and which have subsequently been subjected to uniformly controlled drying and operating conditions at the loading plant. subparagraphs shall be performed on inspection lots (see 4.3.1) of the components or assemblies design
35、ated in the applicable paragraph headings. Inspection for critical defects (and 4.3.2 Examination.-The examinations listed in the following 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-f MIL-D-46256B (MU) major defects, when so specified) shall

Sampling plans 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 Government. Instead of applying the AQLs designated herein to the groups of major and minor defects
37、listed, the contractor may elect to apply AQLs to individual defects using an AQL of 0.40 percent for each major defect and an AQL of 0.65 percent for each minor defect. When this method is elected, it shall be applied to . all of the major and minor defects listed in the applicable subparagraphs of
38、 this section, except where 100 percent inspec- tion is specified, and be documented as part of the contractors inspection system.
