While older versions, such as ASME PTC 19.1-2005 , are still referenced, the 2018 edition is the current standard. Having the digital version (PDF) of this standard allows engineers and technicians to:
Every physical measurement contains a margin of doubt. ASME PTC 19.1 shifts the engineering focus away from ambiguous terms like "precision" or "bias" to the formalized concepts of and random error . Unpredictable variations in measurements
These are unpredictable variations that cause data to scatter. PTC 19.1 quantifies this as Random Uncertainty
