Copper units of pressure Wikipedia

While CUP and LUP numbers were intended to be comparable to the crushing power of a given pressure in psi, the numbers are not equivalent. Since a longer duration, lower pressure pulse can crush the cylinder as much as a shorter duration, higher pressure pulse, CUP and LUP pressures frequently register lower than actual peak pressures (as measured by a transducer) by up to 20%. For example, the SAAMI maximum pressure for the 7.62×51mm is given as 52,000 psi (CUP), or 62,000 psi (430 MPa); the

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.

Chamber pressure Wikipedia

Copper crusher method. Through the mid-1960s, 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.

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.

Cartridge Pressure Standards kwk

Because the indicated pressure from crushers is known to be off, SAAMI many decades ago began referring to the indicated pressure from their tests as "Copper Units of Pressure," a clumsy name commonly shortened to "CUP." For low pressure cartridges such as shotshells, lead is used for the crusher, and SAAMI refers to these numbers as "LUP."
