Implementing ASME PTC 19.1 involves a strict, sequential process to validate your test data.
ASME PTC 19.1 is a copyrighted document and is not typically available for free download as a legal PDF. You can find the most recent versions (such as the 2018 or 2013 editions) at authorized retailers:
Next time you see a spec sheet promising “±0.1% accuracy,” smile. Open your ASME PTC 19.1 PDF. And ask the quiet question: “Show me your uncertainty budget.”
ASME PTC 19.1 is far more than a dry technical document. It is a comprehensive and essential guide for any engineer who relies on measurements to make decisions. By providing a clear, systematic, and internationally aligned methodology for quantifying uncertainty, the standard ensures that test results are not only reported but can be trusted. The current 2018 (R2024) edition represents the culmination of decades of best practices, equipping professionals across all industries with the tools they need to design better tests, select better instruments, and ultimately, to know with confidence the true capability of the systems they build and operate.
The standard is the definitive blueprint for evaluating and calculating test measurement uncertainty in engineering applications. Officially titled Test Uncertainty , this Performance Test Code (PTC) supplement provides engineers, scientists, and calibration specialists with a mathematically rigorous framework. It isolates, quantifies, and propagates measurement errors into a single, legally defensible statement of confidence.
PTC 19.1 dedicates significant content to handling . For tests with fewer than 30 readings (which is most industrial performance tests), you cannot use the normal distribution (Z-scores). Instead, the standard mandates the use of the Student’s t-distribution , with tables included in the Appendix.
