  • Chamber Pressure Infogalactic The Planetary Knowledge Core

    Copper Crusher Method. Through the mid1960s, the most common way of measuring pressure was drilling a hole through the chamber of the barrel and inserting a copper slug that fit flush with the chamber walls. When a cartridge is fired, it compresses the copper slug. It is then removed, measured, and compared to the original dimensions.

  • Proof Test Wikipedia

    A proof test is a form of stress test to demonstrate the fitness of a loadbearing structure. An individual proof test may apply only to the unit tested, or to its design in general for massproduced items. Such a structure is often subjected to loads above that expected in actual use, demonstrating safety and design margin.
