4.4.1.3.1 Sampling plan. Table X tests shall be performed on a production lot basis. Sample size shall
be as specified in table IX. If one or more defects are found, the lot shall be screened for that particular
defect and defects removed. Alternatively, parts may be reworked and returned to the lot where defects
do not affect the form, fit, or function of the device, such as marking, residue, etc. Such lots shall be
clearly identified as reinspected. After screening and removal of defects, a new sample of parts shall be
randomly selected and subjected to all tests in table X. If one or more defects are found in the second
sample the lot shall be rejected and shall not be supplied to this specification.
4.4.1.3.2 Disposition of sample units. Sample units, which have passed all of group B inspection, may
be delivered on the contract, if the lot is accepted.
4.4.2 Periodic inspection. Periodic inspection shall consist of group C inspection. Except where the
results of these inspections show noncompliance with the applicable requirements (see 4.4.2.1.4),
delivery of products which have passed groups A and B inspections shall not be delayed pending the
results of these inspections.
4.4.2.1 Group C inspection. Group C inspection shall consist of the inspections specified in table VII,
