4.6.3.2.2 Manufacturer's production inspection. If the manufacturer performs tests equal to or more stringent than
those specified in group I, subgroup 1, table VI, as the final step of this production process, group A, subgroup 1
inspection may be waived and the data resulting from the manufacturer's production tests may be used instead.
Authority to waive the subgroup 1 inspection shall be granted by the qualifying activity only. The following criteria
must be complied with:
a.
Tests are identical to or more stringent than those specified for subgroup 1 tests.
b.
One hundred percent of the product supplied these tests.
c.
Failure criteria are identical to, or more stringent than, those specified for subgroup 1 tests.
d.
Lot rejection criteria are identical to, or more stringent than, those specified for subgroup 1 tests.
e.
Once approved, future changes require approval from the qualifying activity.
4.6.3.2.3 Subgroup 2 tests. The subgroup 2 tests shall be performed on an inspection lot basis for ER parts. A
random sample of resistors shall be selected in accordance with table VIII. In the event of one or more failures, the
lot is rejected. The rejected lot may be re-screened and the defects removed and resubmitted to table VIII sample
plan. If one or more defects are found in this second sample, the lot is rejected and shall not be supplied to this
specification. (NOTE: This corrective action applies to the original quality defect found. If a another defect type is
found in the second sample, a re-screen for that defect is also permitted).
4.6.3.2.4 Subgroup 3 tests. Subgroup 3 shall be performed on an inspection lot basis for ER parts. A sample of
13 parts shall be randomly selected. If one or more defects are found, the lot shall be rescreened and defects
removed. A new sample of 13 parts shall be randomly selected. If one or more defects are found in this second
sample, the lot shall be rejected and shall not be supplied to this specification.
