3.4 Sensitivity.
3.4.1 Nonfunctioning. The primer shall not function under an
applied energy value of 8.85 inch ounces minimum (min.) when
tested as specified in 4.5.2.1.
3.4.2 Functioning. The primer shall function under an
applied energy value of 82.60 inch ounces maximum (max.) when
tested as specified in 4.5.2.2.
3.4.3 Safety drop test. The primer shall not function as a
result of the five foot cartridge drop specified in 4.5.2.3.
The primer shall function when

the first attempt, without any audible hangfire.
3.6.2 Metal part security. There shall be no evidence of
rupture or metal parts separation in the gun bore or in flight.
3.6.3 Velocity and functioning (proving ground). The
cartridge assemblies shall function and shall impart a corrected
muzzle velocity of not more than 219 feet per second (fps) and not
less than 199 fps. In addition, the velocity standard deviation
of the lot shall be not greater than 4.0 fps.
3.7 Propellant charge uniformity. The M9 propellant lots
shall achieve a velocity of 210 fps (see 4.5.6). This test shall
be required when a lapse of six months or more occurs between
propellant acceptance and LAP initiation.
3.8 Static pressure. The average internal ignition cartridge
pressure plus 4 standard deviations shall not exceed 22,000 psi
(see 4.5.7).
