EVS-EN IEC 61987-1:2024

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.
