AutoCAD P&ID symbols standards

AutoCAD P&ID has four different symbol standards templates JIS, ISA, PIP, ISO/DIN. Depending on your company’s standards, guidelines, templates and region, the one you use will vary. It’s important to start with the correct standard, as changing later will require remapping of your entire diagram. It is not good practice to use two different standards for a P&ID and it should be avoided.

    Hi everyone,

    Our engineering group is in the process to set up P&ID standards. We are working in the Sugar Process Industry and we need to decide between ISO and PIP. We are not entirely sure what the differences are between the two. My understanding is that ISO is more generic whereas PIP is more process industry specific. Can anyone give us some advise?

    Hi Jenner,
    Thanks for your neatly scripted answer, it’s very helpful.

    For me in my organisation, I get some requirements where I need to compare these and revert to the customer, Do you have any additional information in comparison to these.
