manufacturing of copper crusher for measuring of chamber pressure

Chamber pressure Wikipedia

It is then removed, measured, and compared to the original dimensions. Using the known properties of copper, the chamber pressure can then be calculated and expressed in copper units of pressure (CUP). While there are now more accurate methods of measuring chamber pressure, the copper crusher method is still used for verifiion purposes.

Copper Unit of Pressure (CUP) Defined by Hodgdon « Daily

Apr 18, 2015 · A: Copper Unit of Pressure (CUP) is a measurement used in the ammunition industry to determine the chamber pressure created by a cartridge load. Originally, a precisely formed copper slug was placed in a fixture over the chamber. When the cartridge was fired, the amount of crushing measured on the slug allowed engineers to determine the pressure.
