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 Commander, ARDC, ATTN:
DRSMC-QAA-Q (D), Dover, NJ 07801. If there is a change in
material, in the cycle time, if a cavity is reworked, or a new
cavity is used, a new curing time shall be established and approved.
4.5.1.8 Dimensional control of stamped or formed parts. In
place of the normal sampling associated with the Classification of
Defects, and with the approval of the Contracting officer, a sample
of at least ten (10) parts shall be dimensionally inspected to
qualify the tool used in the stamping process for use in
In addition, a random sample of five (5) parts shall be
production.
selected from the last portion of each day's production for
dimensional inspection as a control of the tool during production.
If any defective parts are found during qualification of the
tool, the tool producing the defective part shall not be used in
production.
If any defective parts are found when inspection is performed
for control of the tool, the tool producing the defective part shall
be removed from production. Further, that portion of production
since the last tool control check shall be returned to the
contractor for corrective action.
All tools 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.
4.5.1.9 Spring embrittlement. The spring shall be stretched
(see 3.9) along its longitudinal axis until the spring no longer
returns to its original position. When the spring no longer returns
to its original length or profile, it shall be considered
permanently distorted. Any spring that cracks or breaks prior to
(Destructive Test).
this point shall be classed defective.
