Background
Process Plant industries need an effective international standard for exchanging:
- process flow diagrams (PFDs)
- piping and instrumentation diagrams (P&IDs)
AP 221 , Functional Data and Schematic Representation for Process Plant
- includes the exchange of P&IDs
- AIM development is scheduled to restart in mid-2000
AP 212, Electrotechnical Design and Installation
- includes much of the capabilities for electrical schematics
other industries have similar requirements
- utilities, hydraulics, avionics, building systems, ship systems,…
