Copper units of pressure

Copper units of pressure or CUP, piezo = 1.52 * crusher 18,000. Likewise, there is a conversion approximation formulas for estimating between CIP (European) crusher pressures (which are recorded in multiples of 50 bar) and piezo ratings, consistent with different assumptions for CIP vs. SAAMI crusher test conditions

On page 20 of SAAMI Specs the pressure is listed in CUP's is 45,000 on a copper crusher pressure gun. On page 28 you will see it is 35,000 PSI on Piezo transducer pressure gun. Do the conversion factor on, lets say 4 of you favorite calibers and see if the conversion is correct. Doesnt really matter,it still doesnt change,SAAMI Specs.

Based on experimental and numerical analysis, it is evident that the piezo pressure observed is higher (closer to true pressure) than copper crusher pressure at 25 mm distance from chamber end. Therefore, piezo pressure is more accurate and reliable to ensure effective ammunition proofing and due safety of
