ASME PTC 19.1 covers various aspects of performance testing, including:
Caused by environmental changes, friction, or electrical noise.
While PTC 19.1 is a supplement, its methods are mandatory for nearly all other ASME Performance Test Codes, such as (Steam Turbines) or asme ptc 191 pdf
Consistent, repeatable errors (e.g., a miscalibrated instrument).
how those tiny doubts add up and change the final test results. Core Concepts of Test Uncertainty ASME PTC 19
ASME PTC 19.1 is a performance test code (PTC) that provides guidelines for testing the performance of instruments and instrument systems used in various industries, including power generation, oil and gas, and chemical processing. The code is designed to ensure that instruments and instrument systems are accurately measuring and controlling process variables, such as temperature, pressure, flow rate, and level.

Commonly referred to as the "Test Uncertainty" standard, it is an indispensable part of the ASME Performance Test Codes (PTC), which govern the planning, execution, and reporting of performance tests for a vast array of machinery and industrial processes. For engineers across all disciplines, understanding and applying ASME PTC 19.1 is not just a matter of technical rigor—it is a necessity for ensuring reliable, defensible, and comparable test results. Core Concepts of Test Uncertainty ASME PTC 19
Implementing ASME PTC 19.1 involves a strict, sequential process to validate your test data.
The standard also utilizes the concept of Type A and Type B uncertainty evaluations, aligning with internationally recognized metrology guidelines:
The object of ASME PTC 19.1 is to define, describe, and illustrate the terms and methods for providing meaningful estimates of uncertainty in test measurements, parameters, and methods, and to show their effects on derived test results. It is designed to be accessible for engineers and scientists interested in objectively assessing measured-parameter data quality. The standard is explicitly applicable to a wide range of applications, with uncertainty sources classified either by their presumed effect (systematic or random) or by the process used to quantify them (Type A or Type B).
