satisfactorily pass the check test for deterioration specified in
MIL-P-60316 immediately before the M32 primer lot is assembled
into the ignition cartridges.
4.4.3.2 Proving ground test (see 3.3). The cartridges shall
be observed for the following characteristics:
a.
Misfires, Major defect (see 3.3.1)
b.
premature burst, Critical defect (see 3.3.2)
Impact functioning, Major defect (see 3.3.3)

a.
b.
Four or more improperly impact functioning occur
c.
One or more short rounds occur
d.
One or more premature burst occurs
e.
One or more metal parts separation occurs
f.
Horizontal range standard deviation at charge O or
charge 4 is exceeded
4.4.3.2.2 Production Sampling. After three consecutive lots
have complied with the criteria of 4.4.3.2.1, forty-eight random
