4.3.1.1 Inspection lot. An inspection lot, shall consist of all the connectors of the same type
designation, produced under essentially the same conditions, and offered for inspection at one time.
However, at the discretion of the Government, an inspection lot may be composed of connectors
representing a number of contracts or orders and may consist of different types of connectors in any of
the following combinations:
a. Types UG-155/U and UG-287/U, latest versions.
b. Types UG-208/Uand UG-216/U, latest versions.
In combination lots, the number of samples of each different type of connector taken from the lot shall be
in approximately the same proportion as the number of each type making up the lot.
4.3.1.2 Resubmitted lots. If an inspection lot is rejected, the supplier may replace it with a new lot,
rework it to correct the defects, or screen out the defective units, and submit it again for acceptance
inspection. Resubmitted lots shall be kept separate from new lots and shall be clearly identified as
resubmitted lots.
