IEC 61298-1:2008

Process measurement and control devices - General methods and procedures for evaluating performance - Part 1: General considerations

IEC 61298-1:2008 specifies general methods and procedures for conducting tests, and reporting on the functional and performance characteristics of process measurement and control devices. The methods and procedures specified in this standard are applicable to any type of process measurement and control device. The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function) between the inputs and outputs, and include analogue and digital devices. For devices that require special tests, this standard should be used, together with any product specific standard specifying special tests. It covers general principles which apply to the series.

Dispositifs de mesure et de commande de processus - Méthodes et procédures générales d'évaluation des performances - Partie 1: Généralités

La CEI 61298-1:2008 spécifie les méthodes et procédures générales pour l'exécution des essais portant sur les caractéristiques fonctionnelles et les caractéristiques de performances des dispositifs de mesure et de commande de processus. Les méthodes et les procédures spécifiées dans cette norme sont applicables à tout type de dispositif de mesure et de commande de processus. Ces essais sont applicables à tout dispositif à condition que ce dispositif soit caractérisé par ses propres grandeurs d'entrée et de sortie et par la relation spécifique (fonction de transfert) entre les entrées et les sorties. Ils concernent les dispositifs analogiques et numériques. Pour les dispositifs nécessitant des essais spéciaux, il convient que la présente norme soit utilisée en conjonction avec la norme particulière de produit spécifiant ces essais spéciaux. Elle les principes généraux qui s'appliquent à l'ensemble de la série.

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 app
