24、submit a first article sample to the Government facility designated by the contracting officer for evaluation in accordance with the provisions of 4.2.2. The first article sample shall consist of twenty-five (25) assemblies and twenty-five (25) complete sets of parts which have been produced by the
25、contractor or furnished by a supplier, and which 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-R-48032 13 W 7777706 0315544 7 W MIL-R-48032 (PA) have been manufactured using the same production processes, procedures and equipment which will b

Prior to submission, the contractor shall inspect the sample to the degree necessary to assure that it conforms to th
27、e requirements of the contract, and submit a record of this inspection with the sample, including statements of findings for materials, processes and tests. A sample containing known defects will not be submitted unless specifically authorized by the contracting officer. (A first article sample, or

32、nspected to determine conformance with applicable requirements. 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 exis

Changes to the process, specifications or drawings, not affecting safety, per- formance, interchang
35、eability OP storage, as determined by the Government, shall not be deemed to alter the homogeneity of an inspection lot. All material subnitted for inspection in accordance with this specification shall comply with the homogeneity criteria specified herein, regardless of the type of sampling procedu
36、re which is being applied to determine conformance with requirements. Lot numbering, as required, shall .be in accordance with MIL-STD-1168. 4.3.1.1 Curing Batch (See paragraph 4.3.4.i0).-A batch shall be defined as the number of assemblies cured under the same condi- tions, in the same oven, at one
37、 time. 4.3.2 Inspection Molded Parts - Insulator.-A sample of ten (10) ring insulators shall be randomly selected from each hours production and subjected to the inspections as specified in 4.3.3.5. In addition, whenever production is resumed after a downtime period or at the start of a new shift, t
38、he first five (5) insulators produced shall also be inspected. If one or more insulators is found to be defective, the group represented by the sample and the last accepted batch shall be screened 100%. subparagraphs shall be performed on inspection lots (See 4.3.1) of the components or assemblies d
39、esignated in the applicable paragraph 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
40、 used if approved by the Government. Instead 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
41、this method is elected, it shall be applied to all of the Major and Minor Defects listed in the applicable subparagraph of this section, except where 100 percent inspection is specified, and be docu- mented as part of the contractors inspection system. Equipment necessary for the performance of the
42、inspections listed shall be in accordance with 4.3.5. 4.3.3 Examination.-The examinations listed in the following 4.3.3.1 Segment Electrode (See dwg. 9256833). 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-R-48032 13 W 7777706 031554b 2 Categ
