MIL-C-64030(AR)
4.4.3 Testing. Testing is described in the first article and
quality conformation inspection "Classification of Defects and
Tests" form and in 4.5.2.
4.4.4 Inspection equipment. The inspection equipment
required to perform the examination and tests prescribed herein is
described in the "paragraph/inspection method" column in the
Classification of Defects and Tests forms beginning with paragraph
4.4.2.1. The contractor shall. submit for approval inspection
equipment designs in accordance with the terms of the contract.
See Section 6 of MIL-A-48078, and Section 6.2 herein.
4.5 Dimensional control of molded or plastic 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) parts (as
molded) from each cavity shall be fully inspected dimensionally
(all dimensions on drawing) to quality 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 cavit
shall be inspected for at least the defects listed in 4.4.2.1
through 4.4.2.62 after continuous production of each 5,000 parts
or at the end of each week, whichever occurs first. If any
defective parts are found during qualification of the cavity, the
cavity producing the defective part(s) 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 the
defective part(s) shall be removed from production. Further, that
portion of production since the last control check shall be
returned to the contractor for inspection for each separate 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 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 Contracting Officer to substantiate the
request. Contractor designs of gages and test equipment required
to perform the inspections listed herein shall be submitted in
accordance with 4.4.4 and 6.2 herein, to Commander, ARDEC, Dover,
New Jersey 07801-5001, ATTN: AMSMC-QAT-I(D) for approval prior to
manufacture of equipment. The noted sub-paragraphs identify those
items and minimum inspection 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 (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 dimensional stability is attained. The inspection data used
in determining the curing time shall be sent to ARDEC, Dover, New
Jersey 07801-5001, ATTN: AMSMC-QAT-M(D). Whenever the following
