scope:
This appendix details the procedures to conduct the chamber pressure, velocity and action time tests. These tests are performed simultaneously. This appendix and supporting annexes are a mandatory part of the specification.
a. The chamber pressure test determines the pressure exerted in the chamber (cartridge case mouth location) of a weapon. The test is performed as a safety measure to insure that the pressure developed by the ammunition is safe for firing in the weapons for which it is intended.
b. The velocity test determines the velocity level and uniformity of the ammunition.
c. The action time test determines the overall primer ignition, propellant burning time, and barrel time (to antenna bar).
