In place of normal sampling and inspections associated with the Classificati
38、on of Defects, and after a curing time for the parts has been approved (see Note 1) a sample of three (3) parts (as molded) from each cavity shall be fully inspected dimensionally to qualify a new or reworked cavity for use in production. Each molded part shall carry the individual cavity identifica
39、tion. As a control of each cavity during production, the above quantity of parts from each cavity shall be inspected for at least the defects listed in paragraphs 4.4.2.1, after continuous production of each 5,000 parts or at the end of each week, whichever occurs first. Of the three (3) samples, on
40、e (I) sample shall be the last part 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 parts are found when inspection is performed for the control of the cavity, the cavity producing
41、 the defective part shall be removed from production. Further, that portion of production since the last control check shall be returned to the contractor or inspection for each separate type of defect according to MIL-STD-105, using an AQL of 0.40 percent for each major defect and ana AQL of 0.65 p
42、ercent for each minor defect. All cavities removed from production because of some fault, may, after reworking be returned to production providing they pass the qualification test above. The contractor may request a change of inspection frequency providing he presents objective evidence to the Contr
43、acting Officer to substantiate the request. Contractor design of gages and test equipment required to perform the inspections listed herein shall be submitted per 6.3 for approval prior to manufacture of equipment. The noted subparagraphs identify those items and minimum inspections subject to the r
44、equirements of this paragraph. 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 part comes out of the mold until dimensio
45、nal stability is attained. The inspection data used in determing the curing time shall be sent to ARE, Dover, New Jersey 07801, ATTN: AMSMC-QAT-M(D). If there is a change in material, or in the cycle time, or if a cavity is reworked, or a new cavity is used, a new curing time shall be established an
46、d approved. 4.5.2 Moisture content. 4.5.2.1 Starter composition. The method of determining the percentage of moisture in the starter composition shall be in accordance with MIL-P-223, heated until a constant weight is obtained for four (4) hrs. at 70W. Observation shall be made for compliance with t
47、he applicable requirement. 19 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-1-70534 13 77977Ob 0355bOb 7 7 MIL-1-70534 (AR) O 4.5.2.2 Imiter composition.
