4.3.1.4.1 Sampling plan. A sample of parts shall be randomly selected in accordance with table IV. If
one or more defects are found, the lot shall be screened for that particular defect and defects removed.
After screening and removal of defects, a new sample of parts shall be randomly selected and subjected
to all tests in accordance with table IV. If one or more defects are found in the second sample, the lot
shall be rejected and shall not be supplied to this specification. Group B inspection shall be performed in
any order acceptable to the Government.
4.3.1.4.2 Disposition of sample units. Sample units, which have passed all the group B inspection shall
be delivered on the contract or order, if the lot is accepted.
4.3.1.4.3 Action in case of lot rejection. When an inspection lot is rejected on group B inspection, the
supplier shall immediately investigate the cause of failure and take corrective action to assure that
subsequent lots do not contain the same defect or defects.
