Instead of hunting for the withdrawn , buy IEC 81346-1:2022 (the latest edition). It contains all the useful rules from 61346-1 plus a decade of improvements. Price is similar, but it is compliant with modern regulatory frameworks like ISO/IEC 81346 series.

Within each function, assign physical locations: +FRAME_A, +CONTROL_BAY. Instead of hunting for the withdrawn , buy
On , the International Electrotechnical Commission (IEC) released IEC 61346-1:1996 . It wasn't just a naming guide; it was a "horizontal standard" designed to create a common structure for information. It introduced three key "aspects" to view any system: Function (=) : What the object is doing. Product (-) : What physical item is being used. Location (+) : Where the object is physically located. 3. The Growing Pains Below is a draft review of the standard
The standard covers the general requirements for documentation and graphical symbols used in electrotechnology, including:
Before the 1990s, engineering documentation was chaotic. A pump might be labeled "P-101" by the mechanical engineer, "M-430" by the electrical engineer, and "PUMP-FW-01" by the instrumentation engineer. This led to massive confusion during commissioning and maintenance.
