When the Copper Units of Pressure was established the reference medium was a standard size plug of copper that was placed in the crusher. ... The switch to piezo gear greatly reduced the costs of shooting pressure data and, thereby, conforming to SAAMI specs.-91 . On a day of seclusion and utter confusion, ... The copper crusher is …

The SAAMI Method uses a conformal transducer, which conforms to the outside of the case. ... There have been other means to test pressure, such as a copper crusher, or even lead crusher, but they are long retired means. There is no direct correlation between this antique pressure measurements to the modern Piezo Transducer. So while it is an ...

But if you apply it to the SAAMI copper crusher number for .223, which is 52,000 CUP, you get 60,930 psi, which is not very close to the the SAAMI conformal transducer MAP of just 55,000 psi. He considers it an insturmentation problem in the article. Overall, there are a number of instrumentation anomalies involved.

The 1970s was the start of three decades of transformation and modernization of the firearms and ammunition industry. SAAMI started the transition of the decades-old copper crusher chamber pressure measurement system (CUP) to the modern piezoelectric transducer chamber pressure measurement system (PSI).

A tabulation of values relating to the compressed length of a crusher cylinder to the chamber pressure.

The superimposed SAAMI copper crusher findings scale well to the EDT PER data because the creep is so similar. The difference in scale magnitude is due entirely to the color hammer spring used. We see that the scaling for the other triggers in …

the rim area of the copper crusher. The copper crusher is then removed and the indentation measured (Fig. 6). The indentation must measure 0.014 inch (read to the nearest 0.0005 inch) with only a 0.001-inch variation to indicate a passing indentation test. Copper Used in the Crusher Both variations of the copper-crusher measuring system (to

Copper crusher levels for centerfire cartridges have nothing to do with lead crusher levels for shotshells. The OP is asking about LUP MAP's compared to PSI MAP's. Your grasp of shotshell ballistics appears to need a refresher, you might start with Lyman's 5th Edition to get a handle on some solid basics.

As you may or may not know, copper crusher readings are usually done by drilling a hole in a case and aligning it with the crusher piston hole in the test gun chamber for firing. However, SAAMI makes that hole drilling optional, so you can optionally let the pressure pop the disc from the case. All they care is that you be consistent.

German police technical guideline [4] specifies measuring the percussion energy of a pistol with a cylinder of pure copper inserted into a measurement cartridge whose length corresponds to the maximum case length allowed by CIP and SAAMI (Fig. 1). These copper cylinders are actually made for the crusher method measurement of …

commonly known as a "crusher gauge". To make a crusher gauge, drill a hole through the barrel into the chamber, fit the hole with a sliding piston, and let the sliding piston crush a small piece of lead against an anvil when the shot is fired. The higher the pressure, the more the lead cylinder is deformed. The crusher

Comparing the compressed length of the copper crusher rod from the pressure barrel to a corresponding length in the tarage table produced a reading in copper units of pressure or (CUP). Due to mechanical and metallurgical delays in the response of the piston and crusher rod to pressure forces, pressure readings were considered to reflect only ...

Both SAAMI and CIP used the copper crusher method until the advent of inexpensive, reliable piezoelectric strain gauges, at which point, both organizations converted their methodologies to take advantage of the newer technology. The copper crusher method was the standard for small arms pressure measurements since the late …
