ASME PTC 19.1 is the American Society of Mechanical Engineers' standard for Test Uncertainty

The 2005 version focused on single test parameters (e.g., uncertainty of a pressure gauge). The 2018 PDF introduces expanded guidance on —when two sensors share the same calibration source (e.g., two pressure transducers calibrated on the same deadweight tester). Failing to account for correlation can cut your calculated uncertainty in half artificially. asme ptc 191 pdf

. If you are looking for preview versions or specific sections, they are often hosted on platforms like ASME PTC 19

: It details how to mathematically move from the uncertainty of a single sensor (like a thermometer) to the uncertainty of a complex calculated value (like thermal efficiency). asme ptc 191 pdf
