ASME PTC 19.2, titled serves as a specialized guide for measuring pressure during the performance testing of various power plant and mechanical systems. While individual test codes (like PTC 22 for gas turbines) define what to test, PTC 19.2 defines how to measure pressure with the required precision. Key Objectives
: Procedures for calculating measurement uncertainty and corrections to be applied. asme ptc 192 pdf
B40.100 covers general pressure gauge requirements (sizes, dials, connections). PTC 19.2 is strictly for performance testing, not everyday process measurement. ASME PTC 19
