ISA5.1 Scope
The standard is suitable for use whenever any reference to an instrument is required in the chemical, petroleum, power generation, air conditioning, metal refining, and numerous other industries.
The standard is intended to provide sufficient information to enable anyone reading a flow diagram and having a reasonable amount of plant knowledge to understand the means of measurement and control of the process without having to go into the details of the instrumentation that require the knowledge of an instrument specialist.
ISA5.1 Purpose
The purpose of this standard is to establish a uniform means of designating instruments and instrumentation systems used for measurement and control. To this end, a designation system is presented that includes symbols and an identification code.
The differing established procedural needs of various organizations are recognized, where not inconsistent with the objectives of the standard, by providing alternative symbolism methods. A number of options are provided for adding information or simplifying the symbolism, if desired.
ISA5.1 2022 Revision
This revision of ISA-5.1 is intended to provide usage clarifications and correct technical and typographical errors that have been uncovered over the years since the 2009 version. The changes from the 2009 version are listed in Annex C.
The instrumentation symbolism and identification systems described in this standard reflect the collective user experience gained since the original ISA Recommended Practice RP-5.1 was published in 1949; was revised and became an ISA and American National Standard in 1984; was reaffirmed without change in 1992; and was revised in 2009. The ISA5 committee greatly appreciates and respects the work of those ISA5 leaders and experts who are listed in the previous versions of this standard.
The symbols and identification methods set forth in this standard are intended as conceptualizing aids, as design tools, as teaching devices, and as a concise and specific means of communication in all types and kinds of technical, engineering, procurement, construction, and maintenance documents. This includes but is not restricted to piping and instrumentation diagrams (P&IDs).
When integrated into a system, the designations and symbols form a dedicated language that communicates concepts, facts, intent, instructions, and knowledge about measurement and control systems that can be applied as appropriate in all industries.
