IEC 61346-1 is an international standard that establishes general principles for the structuring of technical information and systems, particularly through the use of reference designations. While the specific IEC 61346 series has been largely superseded by the IEC 81346 series, it remains a foundational document for engineering documentation and industrial systems. Core Purpose and Scope

6. Notation Rules and Syntax

• Use of delimiters (such as “/” or “.”) to separate hierarchical levels.
• Consistent use of element type codes and instance numbers.
• Rules for referencing multiple identical items (e.g., buses, multiplexed signals).
• Recommendations for composite objects and cross-references.

Most engineers stop here. They use these prefixes to generate tags. But the standard’s hidden power is the relationship between these aspects.

• System level (e.g., "Whole Refinery")
• Functional unit level (e.g., "Crude Distillation Unit")
• Component level (e.g., "Pump P-101A")
