19、y mine to be subjected to this test shall be tested on a suitable testing machine. Care shall be taken to assure that the platens are free of foreign material and that the wedge is axially centered on the lower pla- ten. The dummy mine shall be loaded at a crosshead speed of 0.050 + .O10 inches/minu
20、tes. The load shall be applied until the force specified on the applicahle drawing is reached. load shall then be removed and observation made for any indication of cracks or fracture. Dummy Mines which pass this test may be returned to the lot provided they comply with the dimensional and visual ch

Dimensional contr.01 of molded or pastic parts. -In place of the normal sampling and inspections associated with the Classification of Defects, and after a curing time for the parts has been approved (See Note 1) a sample of three (3:. papts (as molded) from each cqv
22、ity shall be fully inspected dimensionally to qualify a new or rew-ked cavity for use in production. 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 defects

Of the three (31 samples, one (I) sample shall be the last part produced. are found during qualification of the cavity, the cavity pro- ducing the defective part will not
24、be used in productlon. Xf any defective parts are found when inspection is performed fop the control of the cavity, the cavity producing the defective part shall be removed from production. Further, that portion of production since the last contml check shall be returned . The 4.5 . 2 The If any def

26、nt 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 Contract
27、ing Officer to substantiate the request. Contractor designs of gages. and test equipment required to perform the inspections listed herein shall be forwarded to Commander, Picatinny Arsenal, Dover, New Jersey 07801, Attn: SARPA-QA-T- for approval prior to manufacture of equfpnent. The noted sub-para
28、graphs identify those items and minirgum 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 ce,g. every 30, 60 etc mins) until dimensional stability Ls attained, The curing time
29、 will be from the time the part comes out of the mold until dimensional stability is attained. The fnspection data used in determining the curing time shall be sent to Picatinny Arsenal, Dover, New Jersey 07801 Attn: SARPA-&A-A-$. If there is a change in material, or in the cycle time, or if a cavit
30、y is reworked, or a new cavity is used, a new curing time shall be established and approved. 5.
