IEC 61514-2:2004

Industrial process control systems - Part 2: Methods of evaluating the performance of intelligent valve positioners with pneumatic outputs

specifies design reviews and tests intended to measure and determine the static and dynamic performance, the degree of intelligence and the communication capabilities of single-acting or double-acting intelligent valve positioners. The tests may be applied to positioners which receive standard analogue electrical input signals (as specified in IEC 60381) and/or digital signals via a data communication link and have a pneumatic output.

Systèmes de commande des processus industriels - Partie 2: Méthodes d'évaluation des performances des positionneurs de vanne intelligents à sorties pneumatiques

prescrit des revues de conception et des essais destinés à mesurer et à déterminer les performances statiques et dynamiques, le degré d'intelligence et les capacités de transmission de données des positionneurs de vanne intelligents à simple et double effet. Les essais peuvent être appliqués à des positionneurs qui reçoivent des signaux analogiques d'entrée électriques normalisés (comme spécifié dans la norme CEI 60381) et/ou des signaux numériques par l'intermédiaire d'une liaison de transmission de données et qui disposent d'une sortie pneumatique.

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.

International Standard IEC 61514-2 has been prepared by subcommittee 65B: Devices, of
IEC technical committee 65: Industrial-process measurement and control.
This standard is to be read in conjunction with IEC 61514.
The text of this standard is based on the following documents:

INTRODUCTION
New instruments for process control and measurement including valve positioners are mainly

equipped with microprocessors thereby utilising digital data processing and communication

methods and/or artificial intelligence, making them more complex and giving them a consider-

able added value.
Modern intelligent valve positioners are no longer only controlling the valve position, but they

are in many cases also equipped with various facilities for self-testing, actuator/valve condition

monitoring and alarming. The variety of added functionalities is large. They can no longer be

compared with the single function "cam-type" positioners. Therefore, accuracy related

performance testing although still very important is no longer sufficient to demonstrate their
flexibility, capabilities and other features with respect to engineering, installation, maintain-
ability, reliability and operability.
In this standard the evaluation considers performance testing and a design review of both
hardware and software. The layout of this document follows to some extent the framework of
IEC 62098. A number of performance tests described in IEC 61514 are still valid for intelligent
valve positioners. Further reading of IEC 61069 is recommended.
