Overview

This Technical Specification applies to radiation thermometry and addresses all technical data specified in specification IEC/TS 62492-1. It defines standard test methods which can be used by the end user of radiation thermometers to determine or confirm the fundamental metrological data of radiation thermometers with one wavelength range and one measurement field. The purpose of this specification is to facilitate comparability and testability. Therefore, unambiguous test methods are stipulated for determining technical data, under standardised measuring conditions that can be performed by a sufficiently skilled end user to serve as standard performance criteria for instrument evaluation or selection. It is not compulsory for manufacturers and sellers of radiation thermometers to include all technical data given in this document in the data sheets for a specific type of radiation thermometer. Only the relevant data should be stated and should comply with this specification and IEC/TS 62492-1. Infrared ear thermometers are excluded from this Technical Specification. The aim of a test is to determine the measuring temperature range. The measurement uncertainty remains within the specified limits for this temperature range. The measuring temperature range as well as the measurement uncertainty and the noise equivalent temperature difference are the main parameters characterizing a radiation thermometer. These three parameters are correlated with each another, and the noise equivalent temperature difference at the lower limit of the measurement temperature range is generally greater where the uncertainty is greater, too. The responsible committee is K 961 "Elektrische Messwertaufnehmer und Messgrößenumformer" ("Electrical measurement sensors and transducers") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
