SIST EN 61514-2:2013
(Amendment)Industrial process control systems - Part 2: Methods of evaluating the performance of intelligent valve positioners with pneumatic outputs (IEC 61514-2:2013)
Industrial process control systems - Part 2: Methods of evaluating the performance of intelligent valve positioners with pneumatic outputs (IEC 61514-2:2013)
This part of IEC 61514 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. An intelligent valve positioner as defined in Clause 3 is an instrument that uses for performing its functions digital techniques for data processing, decision-making and bi-directional communication. It may be equipped with additional sensors and additional functionality supporting the main function. The performance testing of an intelligent valve positioner needs to be conducted with the positioner mounted on and connected to the actuator/valve assembly the positioner is to be used on. The specific characteristic parameters of these combinations such as size, stroke, friction (hysteresis), type of packing, spring package and supply pressure for the pneumatic part, should be carefully chosen and reported, since the performance of a positioner is greatly dependent on the used actuator. The methods of evaluation given in this standard are intended for testing laboratories to verify equipment performance specifications. The manufacturers of intelligent positioners are urged to apply this standard at an early stage of development. This standard is intended to provide guidance for designing evaluations of intelligent valve positioners by providing: - a checklist for reviewing their hardware and software design in a structured way; - test methods for measuring and qualifying their performance under various environmental and operational conditions; - methods for reporting the data obtained. When a full evaluation, in accordance with this standard, is not required or possible, the tests which are required should be performed and the results should be reported in accordance with the relevant parts of this standard. In such cases, the test report should state that it does not cover the full number of tests specified herein. Furthermore, the items omitted should be mentioned, to give the reader of the report a clear overview. The standard is also applicable for non-intelligent microprocessor-based valve positioners without means for bi-directional communication. In that case an evaluation should be reduced to a limited programme of performance testing and a short review of the construction.

Systèmes de commande des processus industriels - Partie 2: Méthodes d'évaluation des performances des positionneurs de vanne intelligents à sorties pneumatiques (CEI 61514-2:2013)
La CEI 61514-2:2013 spécifie 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 (tels que spécifiés dans la CEI 60381) et/ou des signaux numériques par l'intermédiaire d'une liaison de transmission de données et qui disposent d'une sortie pneumatique. Cette deuxième édition annule et remplace la première édition parue en 2004, dont elle constitue une révision technique. Les modifications significatives sont: la norme a été optimisée pour une facilité d'utilisation et les procédures d'essai ont été revues concernant l'applicabilité pour une utilisation dans des installations d'essai. Les procédures d'essai non réalisables en pratique ont été supprimées ou modifiées.
Sistemi za upravljanje industrijskih procesov - 2. del: Postopki za ocenjevanje lastnosti inteligentnih pozicionirnikov z ventili s pnevmatskimi izhodi (IEC 61514-2:2013)
Ta del standarda IEC 61514 določa preglede zasnove in preskuse za merjenje in določanje statičnih in dinamičnih lastnosti, stopnjo inteligence in komunikacijske zmožnosti enostransko delujočih ali dvostransko delujočih inteligentnih pozicionirnikov z ventili. Preskusi se lahko uporabljajo za pozicionirnike, ki prejemajo standardne analogne električne vhodne signale (kot je določeno v standardu IEC 60381) in/ali digitalne signale prek podatkovne komunikacijske povezave in imajo pnevmatski izhod. Inteligentni pozicionirnik z ventili, kot je določeno v točki 3, je instrument, ki za izvajanje svojih funkcij uporablja digitalne tehnike za obdelovanje podatkov, sprejemanje odločitev in dvosmerno komunikacijo. Lahko je opremljen z dodatnimi senzorji in dodatnimi funkcionalnostmi, ki podpirajo glavno funkcijo. Preskušanje lastnosti inteligentnega pozicionirnika z ventili se mora izvajati tako, da je pozicionirnik nameščen in povezan s sprožilom/sestavom ventilov, s katerim se bo uporabljal. Parametre specifičnih lastnosti teh kombinacij, kot so velikost, takt, trenje (histereza), vrsta pakiranja, paket vzmeti in tlak oskrbe za pnevmatski del, je treba previdno izbrati in sporočati, saj je zmogljivost delovanja pozicionirnika zelo odvisna od uporabljenega sprožila. Postopki za ocenjevanje, ki so podani v tem standardu, so namenjeni za preskusne laboratorije za preverjanje specifikacij lastnosti opreme. Proizvajalce inteligentnih pozicionirnikov se spodbuja, da ta standard uporabljajo v zgodnji fazi razvoja. Namen tega standarda je zagotoviti smernice za oblikovanje ocenjevanja inteligentnih pozicionirnikov z ventili, tako da zagotovi: – kontrolni seznam za strukturirani pregled zasnove strojne in programske opreme; – preskusne metode za merjenje in kvalificiranje njihovega delovanja pod različnimi okoljskimi in delovnimi pogoji; – metode za poročanje o pridobljenih podatkih. Kadar celotno ocenjevanje v skladu s tem standardom ni zahtevano ali mogoče, je treba opraviti zahtevane preskuse, o rezultatih pa poročati v skladu z ustreznimi deli tega standarda. V takšnih primerih mora biti v poročilu o preskusu navedeno, da ne vključuje vseh preskusov, ki so določeni v standardu. Poleg tega je treba omeniti izpuščene postavke, da ima bralec poročila jasen pregled. Standard se uporablja tudi za neinteligentne pozicionirnike z ventili na osnovi mikroprocesorja brez sredstev za dvosmerno komunikacijo. V tem primeru se mora ocenjevanje zmanjšati na omejeni program preskušanja delovanja in kratek pregled konstrukcije.

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 61514-2 has been prepared by subcommittee 65B: Measurement
and control devices, of IEC technical committee 65: Industrial-process measurement, control
and automation.
This part of IEC 61514 is to be used in conjunction with IEC 61514:2000.
This second edition cancels and replaces the first edition published in 2004. This edition
constitutes a technical revision.
The significant changes with respect to the previous edition are as follows:
– The standard has been optimized for usability.
– The test procedures have been reviewed regarding applicability for use in test facilities.
Impractical test procedures were removed or modified.

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/TS 62098. A number of performance tests described in IEC 61514 are still valid for
intelligent valve positioners. Further reading of IEC 61069 is recommended.

Part 2: Methods of evaluating the performance of intelligent
valve positioners with pneumatic outputs mounted
on an actuator valve assembly
1 Scope
This part of IEC 61514 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.
An intelligent valve positioner as defined in Clause 3 is an instrument that uses for performing
its functions digital techniques for data processing, decision-making and bi-directional
communication. It may be equipped with additional sensors and additional functionality
supporting the main function.
The performance testing of an intelligent valve positioner needs to be conducted with the
positioner mounted on and connected to the actuator/valve assembly the positioner is to be
used on. The specific characteristic parameters of these combinations such as size, stroke,
friction (hysteresis), type of packing, spring package and supply pressure for the pneumatic
part, should be carefully chosen and reported, since the performance of a positioner is greatly
dependent on the used actuator.
The methods of evaluation given in this standard are intended for testing laboratories to verify
equipment performance specifications. The manufacturers of intelligent positioners are urged
to apply this standard at an early stage of development.
This standard is intended to provide guidance for designing evaluations of intelligent valve
positioners by providing:
– a checklist for reviewing their hardware and software design in a structured way;
– test methods for measuring and qualifying their performance under various environmental
and operational conditions;
– methods for reporting the data obtained.
When a full evaluation, in accordance with this standard, is not required or possible, the tests
which are required should be performed and the results should be reported in accordance with
the relevant parts of this standard. In such cases, the test report should state that it does not
cover the full number of tests specified herein. Furthermore, the items omitted should be
mentioned, to give the reader of the report a clear overview.
The standard is also applicable for non-intelligent microprocessor-based valve positioners
without means for bi-directional communication. In that case an evaluation should be reduced
to a limited programme of performance testing and a short review of the construction.
