25、ticle Inspection b. Quality Conformance Inspection 4.3 First article inspection. 4.3.1 -111 Submission. The contractor shall submit a first article sample, as designated by the Contracting Officer, for evaluation in accordance with the provisions of 4.3.2 and 4.3.3. The first article sample shall co
26、nsist of the parts/assemblies listed below in the quantities indicated. Part Description Drawing Quant?arts. In place of normal sanpling an6 insGections associated with the Classification of Defects, and after a curing time for the parts has been approved (See Note 1). The Contractor may, itith the
27、appraval of the Government, select a sample of three (3) parts (as molded) from each cavity to be fully inspected dimensioaally (all dimensions on drawing) t3 qualify a new or reworked cavity for use iii production. The molded ?arts shall carry the individaal cavity identification. As a control of e
28、ach cavity during production, the above quantity of parts Erom each cavity shall be inspected for at least the defects listed in 4.4.2.1 after continuous production of each 5,000 parts or at the end of each week, whichever occurs Eirst. Of the three (3) samples, one (1) sample shll be the last part
29、produced. If any defective parts are found during qualification of the cavity, the cavity producing the defective part will not be used in production. If any defective paris are found when inspection is performed for the control of the cavity, the cavity producing the efective part shali be removed
30、from 2roduction. Further, that portion of 2roduction since the last control check shall be returned to the contractor for inspection or each se2xate type of defect according to MIL-STD-105, using an AQL of 0.40 percent for each major defect and an AQL of 0-65 percent for each minor defect. All cavit
31、ies removed fom production because OE some fault, may after reworking, be returned to sroduction sroviding they pass the qualification test above.

32、st. Contractor design of gages and test equfpent required to perform the inspectians listed herein shall be forlrarded to Commander, AMCCOM, Picatinny Arsenal, New Jersey 07806-5000, ATTN: MGMC-QAT-I (D) for approval prior to manufacture of equipment. The noted subparagraphs identify those items and
33、 minimum inspections subject to the requirements of this paragraph. 3 NOTE 1: In establishing a curing time, dimensionally check ten (10) parts from each cavity at periodic intervals (e.g. every 30, 60 etc. mins.) until dimensional stability is attained. The curing time will be from the time the par
34、t comes out of the mold until dimensional stability is attained. The inspection data used in determining the curing time shall be sent to AMCCOM, Picatinny Arsenal, New Jersey 07806-5000, ATTN: ANSIC-QAT-M (D). When a new cavity is substituted, an old cavity reworked, or the material or cycle time c
35、hanged, a new curing time shall be established and approved. $ 16 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-P-78675 (AR) 4.5 Methods of inspection. 4.5.1 Non-activated voltage.
