DIN EN IEC 62828-1:2018-11

This Part of IEC 62828 establishes a general framework for defining reference conditions and test procedures applicable to all types of industrial and process measurement transmitters (PMTs) used in measuring and control systems for industrial process and machinery. These reference test conditions are divided into 'standard reference conditions', which apply when determining the accuracy of measurement, and 'ambient and process reference conditions', which are used to assess the influence of external quantities on the measurement.
