A Reference Designation (RD) is built by combining these aspects with letter codes and numbers. A complete designation tells an engineer exactly what a component does, where it is, and what physical part it represents. The Structure of a Designation
Whether you need to comply with or want to transition to the modern 81346 standard
Focuses on the physical components, products, or modules chosen to implement the function. It is represented by the prefix symbol - . iec 61346-1 pdf
Industrial projects require a clear, standardized language to identify equipment, systems, and components. Without a unified system, engineering documentation becomes confusing, leading to errors during installation, maintenance, and operation. This is where the IEC 61346 standard series becomes essential.

The international standard (titled "Industrial systems, installations and equipment and industrial products – Structuring principles and reference designations – Part 1: Basic rules" ) established the core framework for managing complex industrial technical documentation. Engineering projects often involve hundreds of thousands of components, so having a structured naming convention is essential. The principles introduced by IEC 61346-1 ensure that cross-disciplinary teams share a common language.
We have sensors (OT) and cloud (IT), but we lack the semantic glue in the middle. IEC 61346-1 is that glue. It is represented by the prefix symbol -
: Organizations like ANSI (USA), BSI (UK), or DIN (Germany) offer localized versions of these international standards in PDF format.
This chaos leads to fatal errors: an electrician disconnects the wrong breaker, an operator starts the wrong pump, or a maintenance team wastes hours tracing documentation.
