As part of the Performance Test Codes (PTC) suite, it serves as an instrumented-based standard, giving guidance on: Instrument selection. Setup and installation techniques. Required calculations and corrections. Uncertainty analysis.
The current active version is , which was reaffirmed in 2020.
: Primary standards utilized for high-precision calibration. 3. Installation and Piping Guidelines
ASME PTC 19.2 (2010) serves as a critical supplement to Performance Test Codes, offering standardized procedures for selecting, installing, and calibrating instruments to determine pressure values accurately. The standard covers essential topics ranging from measurement technologies and installation guidelines for pressure taps to the calculation of systematic and random uncertainties.

While summary articles and engineering forums provide conceptual overviews, the full, actionable document containing specific equations, installation diagrams, and tolerance tables must be obtained through legitimate engineering standard clearinghouses. Uncertainty analysis
The ASME PTC 19 series outlines the governing requirements for all instrumentation used in an ASME Performance Test to ensure it falls within a specified uncertainty band. PTC 19.2, specifically, is the "supplement" that focuses solely on pressure. The choice of method, instruments, required calculations, and corrections described in the standard depends on the purpose of the measurement, the allowable uncertainty, and the characteristics of the equipment being tested. This flexibility ensures the standard remains relevant across diverse testing scenarios.
PTC 19.2 minimizes those errors by forcing you to account for:
If you're involved in the performance testing of instruments and measuring systems, I highly recommend downloading the ASME PTC 19.2 PDF. The standard provides a comprehensive guide to testing and evaluating instrument performance, ensuring accuracy, reliability, and compliance with regulations.
This standard is a comprehensive guide for as part of performance testing in power plants, refineries, and other industrial facilities. It's an essential resource for establishing a "level playing field" and ensuring tests are conducted with the highest level of accuracy. The 96-page document covers key areas including:
