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.

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-$.
