Please note that while you searched for "PTC 192," the correct designation for the standard concerning pressure measurement is ASME PTC 19.2. (PTC 19 is a series of instruments apparatus supplements; 19.2 specifically covers pressure measurement).
The only verified repository is the ASME eLibrary or ASME.org.
ASME PTC 19.2 is a copyrighted document. While many users search for a "free PDF" download, the only legal and safe way to obtain the document is through the ASME Digital Collection (asmedigitalcollection.asme.org) or authorized resellers.
Warning regarding unofficial PDFs: Unofficial copies found online may be outdated (superseded), incomplete, or contain altered data. For performance testing used in contractual disputes or legal compliance, only the official, watermarked PDF or print version from ASME is considered valid.
A significant portion of the document is dedicated to uncertainty analysis. It guides engineers on how to combine elemental errors (calibration errors, data acquisition errors, installation errors) to determine a total measurement uncertainty. This is vital for passing a performance test, as test results are only valid if the uncertainty falls within the code's allowable limits.
In performance testing, even a 0.5% error in pressure can lead to:
PTC 19.2 minimizes those errors by forcing you to account for: asme ptc 192 pdf
ASME PTC 19.2 is part of the ASME Performance Test Codes (PTC) series, specifically functioning as an "Instruments and Apparatus Supplement." Titled "Pressure Measurement," this standard provides comprehensive guidance on the terminology, instrumentation, and methodology required to measure pressure accurately during performance tests of mechanical equipment.
While main PTC codes (like PTC 4 for boilers or PTC 10 for compressors) dictate what to test, PTC 19.2 dictates how to measure the specific variable of pressure. It is widely regarded as the industry bible for precision pressure measurement in industrial, aerospace, and power generation applications.
The document details the selection and application of various pressure-measuring devices, including:
Occasionally, a "Work in Progress" (WIP) draft of an upcoming ASME PTC update is circulated for committee review. These drafts sometimes leak online. Warning: A draft version of ASME PTC 192 (if it existed) is invalid for contractual dispute resolution. Only the final, published edition holds legal weight.
