6.5 Check test for possible deterioration. The following test
is designed to prevent primers that have deteriorated from being
assembled into major ammunition items. The test shall be performed
on primers from each lot which have stored under normal conditions
for more than two years or under adverse conditions for any period
of time. If the specification for the ammunition item into which
the primers are assembled does not require that the check test be
performed, the Contracting Officer should insert in the contract a
provision for the performance of the check test. The Contracting
officer will arrange for the contractor to be reimbursed for expense
incurred in his performance of the check test for possible
deterioration. Primer assemblies shall be selected from each lot
for this test.
6.5.1 Functioning. A sample of 315 primers shall be selected
at random from each lot. If 4 or more primers fail to comply with
the requirement specified, the lot shall be rejected. If more than
one defect is found, a second sample of 315 shall be selected at
random and tested. If in the combined first and second sample a
total of 5 or more defects are found the lot shall be rejected. The
test shall be performed as specified in the applicable primer
specification.
