3.4 Transportation vibration. The cartridge shall be safe to transport and there shall be
no evidence of external damage to the cartridge that will affect the intended function (see 6.11
and 6.12).
3.5 Functioning. The cartridge shall comply with the following requirements:
3.5.1 Altitude. The projectile shall function at an average altitude of 600 ± 100 feet over
the temperature range of -65 degrees F to 160 degrees F.
3.5.2 Burning of illuminant assembly. The illuminant assembly shall burn in the air for
30 seconds min. while suspended from the parachute at ambient temperature.
3.5.3 Parachute. Parachute shall properly deploy within 5 seconds of ejection and remain
attached to illuminant assembly over the temperature range of -65 degrees F to 160 degrees F.
3.5.4 Firing. No projectile shall stick in the gun bore. No cartridge case shall stick in the
gun chamber. These requirements shall be applicable over the temperature range of -65 degrees F
to 160 degrees F.
3.6 Hardness. The hardness of the area near the mouth and on the base of the cartridge
case shall be 67 ± 10 on the Rockwell 30 T Scale.
3.7 X-ray examination of ballistic samples. Prior to forwarding the sample cartridges for
ballistic testing, they shall be x-rayed for critical and major defects. A critical defect is defined as
no delay column or no delay carrier. A major defect is defined as missing parachute assembly,
visible cracks in illuminant composition, and blocked or missing delay vent hole.
3.8 Hydrostatic pressure. The cartridge case, less vent holes, shall be capable of
withstanding a hydrostatic pressure of 48,000 pounds per square inch (psi), minimum (min),
without evidence of a rupture of the bottom of the charge cup cavity. Cases especially prepared
for this test shall be identified from regular cases by painting a red strip around the open end, or
any positive identification approved by the procuring activity.
3.9 Workmanship. All parts and assemblies shall be fabricated, loaded and assembled
in a thorough, workmanlike manner. They shall be free of burrs, sharp edges, cracks, dirt, grease,
rust and other foreign matter. The cleaning method used shall not be injurious to any parts, nor
shall the parts be contaminated by the cleaning agents. Exterior surface coatings shall be
continuous; however, a few light scratches not exposing base materials may be permitted. All
required marking and stamping shall be neat and sharply defined.
3.10 Ammunition lot numbering. Ammunition lot numbers shall be assigned in
accordance with MIL-STD-1168
