MIL-B-63299A (AR)
2.  Assure proper system operation by monitoring the
self-checking circuit outputs of the Transmitter Power
supply.
4.4.7 Impact medium.  The impact or target material will
simulate an asphalt surface and will consist of three (3) 1.5 inch
thick particle boards (Clipboard), with a density of approximately
31 pounds per cubic foot.
4.5 Methods of inspection.
4.5.1 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 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 defects listed in the pertaining paragraphs 4.4.2.1
through 4.4.2.30, after continuous production of each 5,000 parts or
at the end of each week, whichever occurs first.  Of the three (3)
samples, one (1) sample shall be the last part produced.  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 forwarded to Commander, ARDC, Dover, New
Jersey  07801, ATTN:  DRSMC-QAT-I(D) for approval prior to
manufacture of equipment.  The noted sub-paragraphs 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 (e.g. every 30, 60 etc
minutes) until dimensional stability is attained.  The curing time
will be from the time the part comes out of the mold until
65
