4.3.3.3 (Cont'd)
This test shall be performed on the initial production sample only.
Failure of the primers to comply with the applicable requirements shall be
cause for rejection of the lot subject to testing of a second sample con-
sisting of double the quantity used in the first test, Failure of the
primers of the second sample to comply with the applicable requirements
shall be cause for rejection of the lot.
Failure of two or more cartridges to comply with the applicable require-
ments shall be cause for rejection of the lot, If one cartridge fails in
the first test, a second sample, consisting of double the quantity used in
the first test may be tested, providing that the action time of the failing
cartridge does not exceed .020 seconds. If any failing cartridges are
found in the second test, the primer lot shall be rejected.
All cartridges for these tests shall be loaded with propellant from an
acceptable lot with known level of performance
The lot shall be rejected when function and casualty defects plus defects
observed in all other firing tests exceed the acceptance number for the
cumulative sample in Table III. If the number of defects found in the first
test exceeds the acceptance number for the first sample, but is equal to or
less than the acceptance number for the cumulative sample, a second sample
consisting of double the quantities specified under function and casualty
test, shall be fired in all the service weapons specified therefor. This
procedure shall apply regardless of the weapon or weapons in which the
firing defects occurred in the first test. If the total number of defects
in the combined first and second samples exceeds the acceptance number for
the cumulative sample the lot shall be rejected. If, in testing a second
sample, defects other than those for which the second sample is being tested
should occur to the extent that they exceed the acceptance number for the
cumulative sample, the primer lot shall be rejected.
Failure of the priming composition to comply with the applicable requirements
shall be cause for rejection of the initial production sample or the primer
lot .
4.3.3.4 Firing defects.-Firing defects and acceptance numbers shall be
specified in Table III.
