IEC TS 62492-1:2008

Industrial process control devices - Radiation thermometers - Part 1: Technical data for radiation thermometers

IEC/TS 62492-1:2008 applies to radiation thermometry. It defines the technical data, i.e. metrological data to be given in data sheets and operating instructions for radiation thermometers with one wavelength range and one measurement field, to ensure that the data and terminology are used consistently. Its purpose is to facilitate comparability and testability. Therefore, unambiguous definitions are stipulated for stating technical data under standardised measuring conditions.

Dispositifs de commande des processus industriels - Pyromètres - Partie 1: Données techniques pour les pyromètres

La CEI/TS 62492-1:2008 est applicable au domaine de la thermométrie par rayonnement (pyrométrie). Elle définit les données techniques, c'est à dire les données métrologiques à fournir dans les feuilles descriptives et les instructions de fonctionnement des pyromètres fonctionnant dans un domaine de longueur d'onde et un domaine de mesure, afin de garantir que les données et la terminologie sont utilisées avec cohérence.Son objet est de faciliter la comparabilité et la testabilité. En conséquence, des définitions non ambiguës sont stipulées pour établir des données techniques, dans des conditions de mesures normalisées.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC/TS 62492-1, which is a technical specification, has been prepared by subcommittee 65B:
Devices and process analysis, of IEC technical committee 65: Industrial-process
measurement, control and automation.
The text of this technical specification is based on the following documents:

Enquiry draft Report on voting
65B/622/DTS 65B/649/CC
Full information on the voting for the approval of this technical specification can be found in
the report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This Technical Specification is one of a series of publications on radiation thermometers.
Future parts of this series are planned with the following titles:
Part 2: Determination of the technical data for radiation thermometers (under consideration);
Part 3: Calibration of radiation thermometers (under consideration).
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• transformed into an International standard,
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

Part 1: Technical data for radiation thermometers

1 Scope
This Technical Specification applies to radiation thermometry. It defines the technical data,
i.e. metrological data to be given in data sheets and operating instructions for radiation
thermometers with one wavelength range and one measurement field, to ensure that the data
and terminology are used consistently.
Technical data for radiation thermometers are frequently given using terms whose meaning is
not clear and therefore open to misinterpretation. Moreover, the data are given for measuring
conditions which are not standardised. Often, influence parameters and mutual
interdependencies of technical data are not given. As a result, the user cannot easily compare
the technical design and performance data of radiation thermometers and tests for
compliance with the manufacturer’s specifications are difficult to carry out.
The purpose of this Technical Specification is to facilitate comparability and testability.
Therefore, unambiguous definitions are stipulated for stating technical data under
standardised measuring conditions.
NOTE 1 Infrared ear thermometers are excluded from this Specification.
NOTE 2 It is not compulsory for manufacturers and sellers of radiation thermometers to include all items given in
this Specification for a specific type of radiation thermometer. Only the relevant data should be stated and should
comply with this Specification.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
