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

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.

Internal Ballistics - Fr. Frog's Pad

Dec 26, 2018  Piezo (PSI) and strain gauge (PSI) are not directly relatable to copper crusher (CUP) due to the differences in the sensitivity of the copper crusher versus the other methods used to measure the pressure. However, new statistical data analysis suggests that for most cartridges ANSI/SAAMI Maximum Average Piezo (PSI) and Maximum Average copper crusher (CUP) taken in a "standard"

Module 05 :: Pressure

In this method, the test barrel is placed over the cartridge case and a steel piston touches the case. A soft copper rod (crusher) sits atop the piston and is restrained by an anvil. When the cartridge fires, pressure pierces the case and drives the piston into the copper crusher. This force shortens the crusher and the length is measured.
