22、e start of regular production the contractor shall submit a first article sample (see 6.1) to a Government approved facility as designated by the contracting officer for evaluation in accordance with the provisions of 4.2.2, and 4.2.3. The first article sample shall consist of three hundred forty (3
23、40) loaded primers and 50 complete sets of parts (i.e., 50 each of every component) which have been produced by the contractor or furnished by a supplier and which have been manufactured using the same production processes, procedures and equipment which will be used in fulfilling the contract. All
24、parts and materials, in- cluding packaging and packing, shall be obtained from the same source of supply as will be used in regular production. Prior to submission, the contractor shall inspect the same to the degree necessary to assure that it conforms to the requirements of the contract and submit

30、ty (340) loaded primers shall be submitted in accordance wich 4.2.1 and tested as specified in 4.3.3.3. 4.3 Inspection provisions 4.3.1 Lot formation.-The term “inspection lot“ as used in this specification is defined as an essentially homogeneous col- lection of units for product from which a repre
31、sentative sample is drawn and inspected to determine conformance with applicable requirements. The sample selected shall represent only that quantitiy of units from which the sample was drawn and shall not be construed to represent any prior to subsequent quantities pre- sented for inspection. Homog
32、eneity shall be considered to exist provided 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 and complies with the
33、 provisions for submission of product as specified in MIL-STD- 105. Changes to the process, specifications, or drawings not affecting safety, performance, interchangeability, or storage, as Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,- MIL-P-98250
34、 13 = 7777706 0317790 5 MIL-P-48250 (PA) 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 comply with the homogeneity criteria specified herein regardless of the type of
35、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 primer assemblies shall contain: a. Parts of one lot interfix number from one supplier. b. Primer mixture from one
36、 batch or blending of batches, which results in homogeneity of all primer mixture used in the loading of a lot. c. Lead azide of the same type from not more than two lots produced by the same manufacturer in accordance with the same specification and same specification revision and which have subseq
37、uently been subjected to uniformly controlled dry- ing and operating conditions at the loading plant. 4.3.2 Examination.-The examinations listed in khe follow- ing subparagraphs .shall be performed on inspection lots (see 4.3.1) of the components or assemblies designated in the appli- cable paragrap
38、h headings. Inspection for critical defects (and major defects, when so specified) shall be 100 percent. 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.
39、 In- stead of applying the AQLs designated herein to the groups of major. and minor defects 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
40、be applied to all of the major and minor defects lirsted in the applicable subparagraphs of this section, except where JO0 percent inspection is specified, and be documented as part of the contractors inspection system. Equipment necessary for the performance of the inspections listed shall be in ac
