copper crusher measurement

Metallic Cartridge Chamber Pressure Measurement

To this day, most published chamber pressure (MAP) data for metallic cartridges is taken by the copper crusher method of measurement. The proper name for this type of measurement is CUP, or Copper Units of Pressure. Another, similar, method uses lead crusher pellets and the resulting pressure values are called "Lead Units of Pressure," or LUP.

WEAPON CHAMBER PRESSURE MEASUREMENT

Peak chamber pressure can be measured mechanically with "crusher gages" or electrically with electrical pressure transducers. Although this paper does not address mechanical measurement, M-ll copper crusher gages were used in conjunction with electrical transducers in many of the dynamic tests.

Correlating PSI and CUP

Before about the 1960's the only measurement system we had for chamber pressure was the copper crusher method. Up until that time, what we now call CUP was commonly known by two different names: CUP and PSI. The two were used practically interchangeably. Of course, this use of PSI was incorrect.
