To align with the standard, your paper should address these critical technical sections:
The latest major revision (ASME PTC 19.2-2010, which remains the standard practice as of 2026) was designed to bring pressure measurement technology in line with modern instrumentation, emphasizing, in particular, the assessment of . 2. Key Objectives and Applications

As an "Instruments and Apparatus" supplement, PTC 19.2 is not a standalone test for a specific machine but a used to support other performance test codes (such as those for turbines, pumps, or compressors). Its primary objectives include:
Covers low-absolute pressure (vacuum) through high-pressure applications.
The current version of this standard is . Core Object and Scope Bourdon tubes, bellows, or diaphragms mechanically move a
The chief objective of ASME PTC 19.2 is to standardize how pressure values are determined in engineering environments where equipment guarantees are evaluated. It bridges the gap between raw laboratory measurements and robust, reproducible industrial test data.
The ASME PTC standards stress that pressure measurement methods, instruments, required calculations, and corrections must be chosen based on the purpose of the measurement, the allowable uncertainty, and the characteristics of the equipment being tested.
ASME PTC 19.2 is an indispensable guide for engineers tasked with accurate pressure measurement. By adhering to the standards outlined for instrumentation, installation, and uncertainty, professionals can ensure that their equipment performance data is accurate, reliable, and compliant with recognized industry standards. Key Objectives and Applications : The protocol for
Automated data logging networks, remote industrial process nodes. Moderate to High
This is perhaps the most significant part of the standard. It provides a structured approach to identifying and quantifying measurement errors:
