ASME PTC 19.2 applies to the measurement of steady-state pressure (and in some cases, transient pressure) in performance tests. It covers a vast range of pressures, from vacuum measurements to ultra-high-pressure systems.
(PTC). While specific test codes (like PTC 22 for gas turbines) tell you to test, the PTC 19 series explains asme ptc 19.2
One of the most valuable contributions of ASME PTC 19.2 is its classification of instruments. It acknowledges that not all pressure gauges are created equal and matches the instrument capability to the uncertainty requirements of the test. ASME PTC 19
To correctly apply the standard, one must adopt its precise definitions of pressure. PTC 19.2 distinguishes between several types of pressure: asme ptc 19.2
