4.3 Sampling
4.3.1 Reproduction. A preproduction sample of five steering control-
ler, manufactured In accordance with 3.2.2, shall be subjected to the
preproduction tests detailed in 4.4 at an activity designated by the pro-
curing activity. Acceptance of the preproduction sample shall be based
on no defects in the sample. Further production of the steering control-
ler by the supplier, prior to the approval of the preproduction sample,
shall be at the supplier's risk.
4.3.2 Lot size. Unless otherwise specified in the contract or order,
each shipment of units of product shall be a separate "inspection lot"
and may differ from the quantity specified in the total order or contract.
In any event, all units of a single "inspection lot" shall be made to the
same design, with the same materials and manufactureing techniques, and
shall be part of one continuous production run.
k. 3.3 Periodic production samples. From each succeeding lot or grand
lot of 300 or less that have passed the quality conformance inspection of
4.5, a random sample of five steering controllers will be selected for
submission to an activity designated by the procuring actitity to deter-
mine compliance of the samples with the requirements of the contract,
specification, and drawings. The steering controllers shall be considered
satisfactory if they meet all specification and pertinent drawings re-
quirements and withstand the tests specified in 4.4 and 4.5. Failure of
the periodic production sample to comply with these requirements will re-
sult in the rejection of the lot, as determined by the procuring actitity.
4.4 Reproduction and periodic production inspection. The preproduc-
tion and periodic production samples, after satisfactorily passing the
quality conformance inspections detailed in 4.5, shall be subjected to the
following tests and examinations. Certified inspection data covering the
results of preproduction and periodic production inspections shall be for-
warded to the procuring actitity.
