No. Despite being an "IEC" (electrotechnical) standard, it is designed for engineering. A pipe, a steel beam, and a software function all get reference designations.

IEC 61346-1, titled "Industrial systems, installations and equipment and industrial products — Structuring principles and reference designations — Part 1: Basic rules," is an international standard published jointly by the International Electrotechnical Commission (IEC) and the International Organization for Standardization (ISO).

Efficient documentation is the backbone of modern industrial engineering. As systems grow in complexity, managing data across mechanical, electrical, and software domains becomes a massive challenge.

The genius of IEC 61346-1 was to recognize that a pump is not just a pump; it is a function, a component, a location, and a signal, all at once. By separating these aspects, the standard gave engineers a universal language.

This aspect defines the physical space or position where an object is installed. This is crucial for maintenance technicians trying to locate a faulty part. Plus sign ( + ) iec 61346-1 pdf

Despite the standard being superseded, there are legitimate reasons to search for and use the original :

The standard suggests concise codes for element designation to avoid verbose identifiers. Good practice:

This aspect focuses on the purpose or task of an object, independent of its physical location or actual hardware. Equals sign ( = )
