• ISA5.7, Process and Instrumentation Diagrams


    Scope

    This subcommittee will utilize symbols and identification per ANSI/ISA-5.1-2009, Instrumentation Symbols and Identification, in combination with other ISA standards, commonly used equipment symbols, and practitioner experience.

    Further, while process flow diagrams (PFDs) are well understood by that name, piping and instrument diagrams (P&IDs) may exist under various other names or variations, such as mechanical flow diagrams; engineering flow diagrams; process and instrument diagrams; and process and control diagrams. The scope shall include these forms of the traditional P&ID.

    Purpose

    To produce and maintain a recommended practice for the development and use of process flow diagrams and piping and instrument diagrams.

    Meetings

    ISA5.7 does much of its work electronically. The subcommittee also holds face-face meetings. Notice of meetings will be circulated in advance to the email list.
