Anotation

IEC 61514-2:2026 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 can be applied to positioners which receive standard analogue electrical input signals (as specified in IEC 60381-1 or IEC 60381-2) and/or digital signals via a data communication link (for example Fieldbus) 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 can be equipped with additional sensors and additional functionality supporting the main function. The performance testing of an intelligent valve positioner is conducted with the positioner mounted on and connected to the actuator/valve assembly the positioner is used on. The specific characteristic parameters of the actuator/valve combination such as size, stroke, friction, type of packing, spring package and supply pressure for the pneumatic part has significant impact on the performance of a positioner. The methods of evaluation given in this document are intended for testing laboratories to verify equipment performance specifications. The manufacturers of intelligent positioners are urged to apply this document at an early stage of development. This document 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 document, is not required or possible, the tests which are required are performed and the results reported in accordance with the relevant clauses of this document. In such cases, the test report will state that it does not cover the full number of tests specified herein. Furthermore, the items omitted are mentioned, to give the reader of the report a clear overview. This document is also applicable for non-intelligent microprocessor-based valve positioners without means for bi-directional communication. In that case an evaluation will be reduced to a limited programme of performance testing and a review of the construction. This third edition cancels and replaces the second edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) in 5.5.2, the standard for the measurements of influence quantities has been changed to IEC 62828-1:2026; b) all references to IEC 61514 have been updated to IEC 61514:2026; c) the aspect of cyber-security has been added in 4.2.7 and 4.2.9. This document is to be used in conjunction with IEC 61514:2026. LIEC 61514-2:2026 specifie les revues de conception et les essais destines a mesurer et determiner les performances statiques et dynamiques, le niveau dintelligence et les capacites de communication des positionneurs de vanne intelligents a simple ou double effet. Les essais peuvent s’appliquer aux positionneurs qui recoivent des signaux d’entree electriques analogiques normalises (tels que ceux specifies dans l’IEC 60381-1 ou l’IEC 60381-2) et/ou des signaux numeriques par l’intermediaire d’une liaison de communication de donnees (par exemple Fieldbus) et qui comportent une sortie pneumatique. Un positionneur de vanne intelligent tel que defini a lArticle 3 est un instrument qui utilise, pour remplir ses fonctions, des techniques numeriques de traitement des donnees, de prise de decision et de communication bidirectionnelle. Il peut etre equipe de capteurs et de fonctionnalites supplementaires venant a l’appui de la fonction principale. Les essais de performance d’un positionneur de vanne intelligent sont effectues avec le positionneur monte et connecte a l’ensemble actionneur/vanne sur lequel le positionneur est utilise. Les parametres caracteristiques specifiques de la combinaison actionneur/vanne, tels que la taille, la course, le frottement, le type de garniture, le bloc ressort et la pression dalimentation pour la partie pneumatique, ont un impact significatif sur les performances d’un positionneur. Les methodes d’evaluation specifiees dans le present document sont destinees aux laboratoires dessai afin de verifier les specifications de performance du materiel. Les fabricants de positionneurs intelligents sont invites a appliquer le present document a un stade de developpement precoce. Le present document est destine a donner des recommandations pour la conception des evaluations de positionneurs de vanne intelligents et fournit a cet effet: - une liste de controle permettant de revoir la conception de leurs materiels et logiciels de maniere structuree; - des methodes dessai pour mesurer et qualifier leurs performances dans diverses conditions environnementales et operationnelles; - des methodes de compte-rendu des donnees obtenues. Lorsqu’une evaluation complete conforme au present document n’est ni exigee ni possible, les essais exiges sont effectues et leurs resultats sont rapportes conformement aux articles pertinents du present document. Dans ces cas, le rapport d’essai precisera qu’il ne couvre pas la totalite des essais specifies ici. En outre, les elements omis sont mentionnes afin de donner au lecteur du rapport une vue densemble claire. Le present document sapplique egalement aux positionneurs de vanne a microprocesseurs non intelligents, sans moyens de communication bidirectionnelle. Dans ce cas, levaluation sera reduite a un programme limite dessais de performance et a une revue de la construction. Cette troisieme edition annule et remplace la deuxieme edition parue en 2013. Ce
