DIN EN 17277:2018-09

This standard considers liquid precipitation and defines a classification for catching-type RI measurement instruments based on their laboratory performance. Standardised calibration tests are described for the assessment of the accuracy of these raingauges both in the laboratory and in the field. The classification does not relate to the physical principle used for the measurement nor does it refer to the technical characteristics of the instrument assembly. The classification is solely based on the accuracy of the raingauge rainfall intensity calibration.
