Testing is described in the first article and qu
39、ality conformance inspection tables. 4.4.3.1 Dimensional control of plastic parts. In place of normal sampling and inspections associated with the Classification of Defects, and after a curing time for the parts has been approved (see Note i) , a sample of three (3) parts (as molded) from each cavit
40、y shall be fully inspected dimensionally to qualify a new or reworked cavity for use in production. The molded parts shall carry the individual cavity identification. As a control of each cavity during production, the above quantity of parts from each cavity shall be inspected for at least the defec
41、ts listed in applicable paragraphs after continuous production of each 5,000 parts or at the end of each week, whichever occurs first. Of the three (3) samples, one (i) sample shall be the last part produced. If any defective parts are found during qualification of the cavity, the cavity producing t
42、he defective parts shall be removed from production. If any defective parts are found when inspection is performed for the control of the cavity, the cavity producing the defective part shall be removed from production. Further, that portion of production since the last control check shall be return
43、ed to the contractor for inspection for each separate type of defect according to MIL-STD-105, using an AQL or 0.40 percent for each major defect and an AQL or 0.65.percent for each minor defect. All cavities removed from production because of some fault, may, after reworking, be returned to product
44、ion providing they pass the qualification test above. The contractor may request a change of inspection frequency providing he presents objective evidence to the contracting officer to substantiate the request. Contractor design of gages and test equipment required to perform inspections listed here
45、in shall be forwarded for approval prior to manufacture of equipment. The noted subparagraphs identify those items and minimum inspections subject to the requirements of.this paragraph. NOTE 1. In establishing a curing time, dimensionally check ten (10) parts from each cavity at periodic intervals (
46、e.g. every 30, 60 minutes, etc.) until dimensional stability is attained. The curing time will be from the time the part comes out of the mold until dimensional stability is attained. If there is a change in material, or in the cycle time, .or if the cavity is reworked, or a new cavity is used, a ne
47、w curing time shall be established and approved. 4.4.4 Inspection equipment. The inspection equipment required to perform the examinations and tests prescribed herein is described in the “Paragraph Reference/Ipsgection Method“ column in the tables starting with paragraph 4.4.2.1. The contractor shal
48、l submit for approval inspection equipment designs in accordance with the terms of the contract.
