Copper units of pressure Wikipedia

Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms.These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively.

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.

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.

Experimental techniques for ballistic pressure

Kistler pressure transducer and the copper crushers. All measurements were taken at 21 ±2°C in a completely enclosed shooting test stand free from weather influences. Results of this series have been used in the second part of this paper to study the dynamic behavior of copper crusher gauges. 2.3. Results and discussion 2.3.1.

CUP, psi & Reloading Data

Jan 04, 2011 Pressure against the piston shortens the crusher. We measure the crusher and consult a table of pressure values provided with each crusher lot. Starting at 0.499 inch, the table lists decreasing lengths in thousandths of an inch and, beside each length, the pressure in copper units of pressure (CUP) that it takes to shorten that much.

BALLISTIC PRESSURE SENSOR REFERENCE GUIDE

The gas check, piston, and copper crusher are installed and retained with the thumb screw. When fired, the gases vent out through the drilled hole and expand the gas check into the piston hole, forming a seal. The resulting pressure acting on the piston forces the copper crusher into a permanent deformation. The crusher is removed and carefully

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.

Correlating PSI and CUP

of chamber pressure. 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. It wasn't much of a
