Industrial-process measurement and control - Data structures and elements in process equipment catalogues - Part 1: Generic structures for measuring equipment (IEC 61987-1:2024)

IEC 61987-1:2024 is available as IEC 61987-1:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61987-1:2024 defines a generic structure in which product features of industrial process measurement devices shall be arranged, in order to facilitate the understanding of product descriptions when they are transferred from one party to another. It applies to the production of catalogues supplied by the manufacturer of such devices and helps the user to formulate their requirements. This document will also serve as a reference document for all future standards which are concerned with process measuring equipment.
In addition, this document also provides a basic structure for the production of further standards listing the properties of process control equipment, for example, for actuators and infrastructure devices.
This edition includes the following significant technical changes with respect to the previous edition:
a) Addition of a subclause “Digital communication” in Clause 5, in order to allow a more comprehensive description of the properties of such an interface;
b) Alignment of clause headings, as described in the introduction, to correspond with those of the IEC CDD.

Mesure et commande dans les processus industriels - Eléments et structures de données dans les catalogues d'équipements de processus - Partie 1: Structures génériques pour équipements de mesure(IEC 61987-1:2024)

IEC 61987-1:2024 est disponible sous forme de IEC 61987-1:2024 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 61987-1:2024 définit une structure générique dans laquelle les caractéristiques de produit des appareils de mesure dans les processus industriels doivent être agencées, afin de faciliter la compréhension des descriptions de produit lors de leur transfert d’une partie à l’autre. Elle s’applique à la production des catalogues fournis par le fabricant de tels dispositifs et aide l’utilisateur à formuler ses exigences. Le présent document sert également de document de référence à toutes les futures normes qui sont concernées par les équipements de mesure de processus.
En outre, le présent document fournit également une structure de base pour la production d’autres normes, qui énumère les propriétés des équipements de commande de processus, par exemple, pour les actionneurs et les dispositifs d’infrastructure.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) Ajout d’un paragraphe "Communication numérique" à l’Article 5, afin de permettre une description plus détaillée des propriétés d’une telle interface;
b) Alignement des en-têtes d’articles sur ceux du dictionnaire de données communes (CDD – Common Data Dictionary) de l’IEC, comme cela est décrit dans l’introduction.
