Published by the International Electrotechnical Commission (IEC), this standard establishes fundamental rules for structuring information related to technical systems. Its primary goal is to ensure that reference designations (the codes you see on wiring diagrams, P&IDs, or equipment labels) are across the entire lifecycle of a system—from design and manufacturing to operation and maintenance.
series, it remains a cornerstone for engineers, architects, and designers who need a systematic way to classify and designate components within complex projects. What is IEC 61346-1? The standard, titled iec 61346-1 pdf
The standard is built on the philosophy that a system can be viewed from multiple "aspects" or viewpoints. This allows engineers to manage complex data by breaking it down into manageable hierarchies: What is IEC 61346-1
IEC 61175 deals with signal names and designations for information exchange. Together with 61346/81346, they form a complete naming ecosystem. The 61346 standard defines what the object is; 61175 defines what the object says . Together with 61346/81346, they form a complete naming
