IEC 61987-24-3:2017

Overview

IEC 61987-24-3:2017 is an international standard published by the International Electrotechnical Commission (IEC) that defines data structures and elements for process equipment catalogues specifically focusing on flow modification accessories for electronic data exchange. This part of the IEC 61987 series provides standardized lists of properties (LOPs) used to describe operating parameters and device characteristics of flow modification accessories employed with automated valves.

The standard promotes seamless information exchange between manufacturers, suppliers, engineering firms, and plant owners by defining clear terminology, structured data formats, and property libraries. This approach enables improved interoperability of engineering tools, automation systems, procurement workflows, and maintenance platforms, ensuring consistent and accurate device descriptions.

Key Topics

• Operating List of Properties (OLOP): Specifies the required operating parameters and functional requirements for flow modification accessories, facilitating requests for quotation and product selection during purchasing processes.
• Device Lists of Properties (DLOPs): Detailed data sets that describe technical attributes, physical characteristics, and performance features of specific types of flow modification accessories such as restriction orifices and diffusers.
• Data Structure Conformance: The LOPs conform to the general data structures established in IEC 61987 parts 10, 11, and 21, providing a unified framework for electronic data exchange.
• Property and Block Libraries: Annexes C and D catalog standardized properties and data blocks, enabling modular and reusable descriptions across various devices and workflows.
• Integration with Related Standards: The LOPs align with terminology and classifications established by IEC 60534-7 and IEC 61360, reinforcing consistency across industrial-process measurement and control.

Applications

• Engineering and Design: Enables detailed and standardized device data to be integrated into computer-aided engineering (CAE) tools, improving accuracy in equipment specification and system simulation.
• Procurement and Supply Chain: Standard property lists simplify request for quotation (RFQ) processes and ensure that vendors provide comparable and comprehensive product information.
• Automation and Control Systems: Facilitates integration of flow modification accessory data into control and monitoring systems, enhancing device interoperability and automation efficiency.
• Plant Maintenance: Supports maintenance management by providing detailed device attributes and operational parameters, streamlining asset management and troubleshooting activities.
• Data Exchange: Enables seamless electronic communication of device data between diverse information technology systems, reducing duplication and errors in manual data handling.

Related Standards

• IEC 61987-10: Defines core data model and structural elements for constructing lists of properties (LOPs) applicable to process control equipment.
• IEC 61987-11: Specifies generic structures for measuring equipment descriptions and composite device handling used in LOPs.
• IEC 61987-21: Establishes generic structures for operating and device lists of properties (OLOPs & DLOPs) for automated valves, supporting extensions for accessories.
• IEC 60534-7: Provides terminology and guidelines related to flow control valves, referenced in defining property terms within this standard.
• IEC 61360: Covers standard data element types and classification schemes for electrical components, supporting consistent property definitions.
