DIN 5031-11:2011-04

This document determines the physical characteristics of radiometers used as measuring instruments for actinic radiation. The document determines essential terms and characteristics, as well as parameters used for marking of actinic radiometers. These parameters serve as comparison of actinic radiometers and as selecting radiometers for recording of a certain radiation effect. In a normative annex the spectral distribution of lamp groups are graphically and numerically listed.
