129055 - ASME PTC 10-2022: Concise Update Overview 

ASME PTC-10 [1] is an internationally recognized code for performance testing of axial and centrifugal compressors. The ASME PTC-10 (published 2023) has gone through a major revision after 25 years as compared to its previous revision in 1997. Among the major changes in the revised code are (1) the use of real gas relationships rather than ideal gas model (2) the use of polytropic process rather than isentropic process throughout the code (3) new calculation methods for polytropic head and polytropic efficiency, also the definition of polytropic efficiency has been updated based on a constant polytropic efficiency along the polytropic path (4) a new correction method for the Reynolds number effect (5) new requirements for flow rate corrections based on difference of leakage ratios (6) multi-point test requirements to verify the performance curves (7) test stabilization for readings and calculated values (8) updated requirements on test instruments, test data treatment, and methods of measurement (9) new methods to calculate test total pressure and temperature (10) new updates on casing heat transfer for test power measurements (11) a new chapter on test uncertainty (12) a new appendix on performance testing of back-to-back compressors.

This paper aims to present a concise overview of the significant technical updates incorporated in the ASME PTC 10-2022 revision.
