IEC 61207-1:2010

Expression of performance of gas analyzers - Part 1: General

IEC 61207-1:2010 specifies the terminology, definitions, requirements for statements by manufacturers and tests that are common to all gas analyzers. It is applicable to analyzers specified for permanent installation in any location (indoors or outdoors) and to such analyzers utilizing either a sample handling system or an in situ measurement technique. It is applicable to the complete analyzer when supplied by one manufacturer as an integral unit, comprised of all mechanical, electrical and electronic portions. It also applies to sensor units alone and electronic units alone when supplied separately or by different manufacturers. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision. The significant technical changes with respect to the first edition are the following:
- all references (normative and informative) have been updated, deleted or added, as appropriate;
- all the terms and definitions relating to this International Standard have been updated;
- all references to "errors" have been replaced by "uncertainties" and appropriate updated definitions applied.
Where only one value is quoted for a performance specification, such as intrinsic uncertainty, linearity uncertainty or repeatability throughout a measurement range, this has now been defined as the maximum value, rather than an average or "representative" value. This was previously undefined. Where zero and 100 % span calibration gases are used, there is now a defined requirement that the analyser must be able to respond within its standard performance specifications beyond its normal measurement range, to allow for any under or over response of the instrument to be recorded. A new Annex A has been added giving recommended standard values of influence.

Expression des performances des analyseurs de gaz - Partie 1: Généralités

La CEI 61207-1:2010 comprend la terminologie, les définitions, les exigences de déclarations des fabricants ainsi que les essais communs à tous les analyseurs de gaz. Elle s'applique aux analyseurs spécifiés pour installation permanente en tout emplacement (à l'intérieur comme à l'extérieur) et aux analyseurs tels que ceux utilisant soit un système de manipulation des échantillons soit une technique de mesure sur site. Elle s'applique à l'analyseur complet lorsque celui-ci est fourni par un seul fabricant en une unité intégrée comprenant toutes les parties mécaniques, électriques et électroniques. Elle s'applique également aux unités de capteur seules et unités électroniques seules lorsqu'elles sont fournies séparément ou par des fabricants différents. Cette deuxième édition annule et remplace la première édition, parue en 1994, et constitue une révision technique. Cette édition inclut les modification techniques majeures suivantes:
- toutes les références (normatives et informatives) ont été mises à jour, retirées ou ajoutées comme il convient;
- tous les termes et définitions en rapport avec la présente Norme internationale ont été mis à jour;
- toutes les références aux erreurs ont été remplacées par "incertitude" et les définitions ont été mises à jour comme il convient.
Lorsqu'une seule valeur est appelée pour une spécification de performance, telle que l'incertitude intrinsèque, l'incertitude de linéarité ou de répétabilité, sur une étendue de mesure, cette valeur est maintenant définie comme valeur maximale plutôt qu'une moyenne ou une valeur représentative. Auparavant, ceci était indéfini. Lorsque les gaz d'étalonnage pour le zéro et le 100 % sont utilisés, il y a maintenant une exigence définie à savoir il faut que l'analyseur soit capable de répondre dans ses performances normalisées au delà de son étendue normale de mesure, afin de permettre l'enregistrement des réponses en deçà ou au-delà. Une nouvelle Annexe A a été ajouté pour donner les valeurs d'influence normalisées recommandées.

EXPRESSION OF PERFORMANCE OF GAS ANALYZERS –

Part 1: General
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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.
International Standard IEC 61207-1 has been prepared by subcommittee 65B: Devices and
process analysis, of IEC technical committee 65: Industrial-process measurement, control and
automation.
