Overview
EN IEC 81346-14:2026 establishes the structuring principles and rules for reference designation of manufacturing and processing systems. Published by CLC and developed in alignment with IEC and ISO efforts, this standard is part of the broader IEC 81346 series. It provides frameworks for clear classification, identification, and labelling of industrial systems, installations, equipment, and products across various sectors, with a special focus on manufacturing and processing environments. By harmonizing structuring and reference designation principles, EN IEC 81346-14 enables precise, consistent, and sector-independent management of technical information throughout the lifecycle of manufacturing and processing plants.
Key Topics
-
Structuring Principles:
The standard sets out guidelines for the structuring of manufacturing and processing systems. It draws on function, product, location, and type aspects to ensure that systems and their components are classified and referenced in a transparent and interoperable way.
-
Reference Designation System:
Defines a multi-aspect reference designation system (RDS-MS) applicable to diverse technical fields, supporting the integration of mechanical, electrical, process, and auxiliary systems under a unified designation framework.
-
Object Classification:
Introduces and clarifies the hierarchical structure of systems, distinguishing between:
- Prime systems: Overarching manufacturing steps or supporting systems.
- Technical systems: Technical solutions or supports for specific process steps.
- Component systems: Clearly defined system elements, often standard off-the-shelf products.
-
Aspect-Driven Identification:
Designations are structured using specific aspect prefixes:
= for functional aspect– for product aspect+ / ++ for host/site installation aspects% for type aspect# for other aspects
-
Integration with Existing Standards:
The structuring and designation rules supplement and reference IEC 81346-1 (basic structuring principles) and IEC 81346-2 (classification codes), ensuring global scalability and compatibility.
Applications
EN IEC 81346-14:2026 delivers practical value across the manufacturing and processing industries by:
- Enhancing Plant Documentation:
Ensures accurate, clear, and consistent technical documentation for complex manufacturing systems, installations, and equipment.
- Supporting Lifecycle Management:
Facilitates planning, design, utilization, operation, and maintenance by enabling unambiguous identification and localization of systems and components.
- Improving Data Consistency:
Provides a foundation for seamless data exchange between engineering, operations, and information systems, reducing errors associated with ambiguous naming or duplication.
- Promoting Interdisciplinary Integration:
Allows for effective collaboration between different technical disciplines (e.g., mechanical, electrical, automation) by using a common designation system.
- Streamlining Digital Transformation:
Supports industrial digitalization initiatives, including Industry 4.0, by defining structures that can be leveraged in software, databases, and digital twins.
