IEC 61346-1 complements related standards:
IEC 61346-1 teaches that systems should be structured hierarchically. Large systems are broken down into sub-systems, which are further divided into sub-assemblies, down to individual components. This is called a . iec 61346-1 pdf
Which is your main focus? (e.g., electrical schematics, piping and instrumentation diagrams (P&ID), or mechanical layout?) Which is your main focus
If your company is starting a new project, it is highly recommended to look for the and its discipline-specific sub-parts (such as Part 2 for classification of objects) rather than relying strictly on the legacy 61346 documentation. Core Structure of a Reference Designation : Focuses on how the object is constructed,
Converting a non-electrical quantity to an electrical one, or vice versa Sensors, microphones, loudspeakers, transducers Storing energy, charge, or matter Capacitors, batteries, buffer tanks E Providing radiant or thermal energy Lamps, lasers, heating elements F Direct protection of lives or equipment Fuses, circuit breakers, surge protectors G Initiating a flow of energy or matter Generators, power supplies, pumps, compressors K Processing signals or information Relays, contactors, logic gates, PLCs M Providing mechanical energy (driving) Electric motors, actuators, turbines P Presenting information Displays, pressure gauges, sirens, indicator lights Q Controlled switching of energy or material flows Power contactors, valves, circuit switchers R Restricting or stabilizing motion, energy, or material flow Resistors, dampers, chokes, pressure reducers S Converting a manual action into a signal Pushbuttons, limit switches, keyboards T Transforming energy while maintaining its character Transformers, frequency converters, rectifiers U Keeping objects in a defined position Enclosures, brackets, cable trays, foundations W Guiding or transporting energy, signals, or material Cables, wires, busbars, pipes, hoses X Connecting objects together Terminals, plugs, sockets, junctions
