  • Copper crushers - dynamic calibration in the laboratory

    Copper crusher gauges are the traditional means to routinely determine peak pressures in large caliber weapons. Most attractive in this method is its simplicity in use. Questionable is the precision in reading the pressure in view of the cumbersome gauge calibration practice which is prone to errors, especially in the low temperature regime.

  • 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.
