The Precision Blueprint: Mastering ASME PTC 19.1 for Test Uncertainty
Note: While ASME PTC 19.1 is based on the ISO Guide to the Expression of Uncertainty in Measurement (GUM) , it is tailored specifically for the practical needs of performance testing engineers. asme ptc 191 pdf
These are unpredictable variations that cause data to scatter. PTC 19.1 quantifies this as Random Uncertainty The Precision Blueprint: Mastering ASME PTC 19
