: Methods for correcting raw data for factors like gravity, temperature, and elevation.
The primary objective of PTC 22 is to determine a gas turbine’s thermal performance at specific test conditions and then correct those results to standard, contractually defined reference conditions. This allows for a fair and objective evaluation, regardless of ambient conditions on the test day. The code provides explicit procedures for determining five key performance parameters:
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. ⚠️ : Always obtain standards from official sources
One of the most nuanced aspects of PTC 192 is distinguishing between correctable degradation and non-correctable wear.
Whether you are using a classic Bourdon tube gauge or a modern digital transmitter, the principles of provide the framework for measurement confidence.
The document also provides guidance for setting up instrumentation and determining measurement uncertainty, along with information on instrument type, design, applicable pressure range, accuracy, output, and relative cost. : Methods for correcting raw data for factors
The current active version is , which was originally published in 2010 and reaffirmed in 2020. The standard spans 92 pages and is available in print or PDF format. The "R2020" designation confirms this 2010 edition remains in effect, meaning no technical changes have been made——the code has simply been reviewed and confirmed as still relevant.
