is a primary industrial standard published by the American Society of Mechanical Engineers (ASME) that dictates the official guidelines for accurate pressure measurement instruments and apparatus . Formally known as a supplement to the ASME Performance Test Codes (PTCs), this technical document provides engineers, plant operators, and manufacturers with uniform procedures to evaluate, set up, and correct pressure instruments during high-stakes equipment performance tests. The Purpose and Evolution of ASME PTC 19.2
No measurement is valid without a traceable calibration. This section of the standard would outline the requirements for calibrating pressure instruments against known standards, including the use of piston gauges, deadweight testers, or other reference devices.
: Guidance on various instrument types, including their design, applicable pressure ranges, and relative costs. It specifically mentions devices such as: Piston gages and vacuum gages (e.g., Bayard-Alpert Ionization chambers and thermocouple gages. Installation & Setup : Instructions for setting up pressure taps and probes to minimize interference and measurement error. Uncertainty Analysis : Procedures for determining the allowable uncertainty asme ptc 192
