process, in accordance with the same drawing, same drawing
revision, same specification and same specification revision.

tion, size, and presentation is described in MIL-STD-105,

lot or batch is to be presented and identified by the con-
tractor, shall be designated or approved by the Government

characteristics shall require 100 percent inspection of all
items in the inspection lot. A sample shall be selected at
random from each inspection lot in accordance with the ap-
plicable major or minor characteristic table (see Table I
and Table II) , and inspected for all characteristics in the
applicable classification. Any characteristics in the
sample found to be defective shall reject the inspection lot.

fication need not be followed as long as all characteristic
inspections are performed.
