project, you should look for the IEC 81346 PDF series instead. Where to Find It
If you are working on legacy systems or transitioning to the newer , having the IEC 61346-1 PDF is essential for: Maintaining Older Documentation
"Industrial systems, installations and equipment and industrial products — Structuring principles and reference designations — Part 1: Basic rules"
: By combining these aspects with specific letter codes, you create a "Reference Designation" (RDS) that tells you exactly what a part is and where it fits. For example, a motor might be designated by its function in a ventilation system rather than just being called "Motor #5." Hierarchical Structure
IEC 61346-1 is the foundational international standard for structuring technical information and systems . While it has been largely superseded by the

It is important to note that IEC 61346 was withdrawn and replaced by IEC 81346-1:2009
