IEC 62828-1 Revised

IEC 62828-1:2017 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. The IEC 62828 series cancels and replaces the IEC 60770 series and proposes revisions for the IEC 61298 series.
