1. Introduction In the world of industrial automation, the reliability of measurements directly impacts product quality, safety, and efficiency. Before a pressure transmitter, temperature sensor, or flow meter is installed in a refinery, power plant, or chemical reactor, its performance must be rigorously verified. IEC 61298-2:2008 – titled “Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions” – provides the globally recognized methodology for conducting such evaluations.
