227· The copper crusher gauge had a nominal height of 4.91 mm and a nominal diameter of 3.0 mm. The 12.7 × 99 ammunition filled with the gun powder type 0.50 inch (WC 860) have been used to achieve the firing tests. A full metal jacket projectile 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 (lbf/in ), 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 ps

This work compares pressure measurements made with two different types of piezoelectric transducers (C.I.P. and SAAMI) to measurements made using copper crushers.
pressure measuring through copper crushers. 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 . Let''s go through a couple of examples to show how the formula works. The formula PSI. crushers work at standard temperature and Engineering:Chamber pressure HandWiki,Copper crusher method Through the mid1960s, 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.

Expert control for high pressure grinding rolls How do they measure cup pressure The Firing Line Forums,1022· For example, the 4570 is rated at both 28,000 CUP and 28,000 psi because, in that chamber, at that pressure range, the two measure the same. But if you look at the .308 Winchester, the maximum pressure is 52,000 CUP but 62,000 psi, so by the time you get to 62,000 psi, the copper crusher is already measuring 10,000 psi too
