These differences are recognized when they are consistent with the objectives of this standard, by providing alternative symbol and identification methods.

The ISA standard is widely applied in commercial process software, which is used for measuring, monitoring, and controlling actual process production ISA, The system is intended to promote a the fullest and quickest comprehension by the operators of the information that is to be conveyed through the display, and b uniformity of practice throughout the process industries.

Resulting benefits are intended to be a a decrease of operator errors, b a shortening of operator training, and c generally better and easier matching of the information—transmission intent of control system designers with the reception and interpretation of results by plant operators. The standard is suitable for use in the chemical, petroleum, power generation, air conditioning, metal refining, and numerous other industries. Symbols are provided for interfacing field instrumentation, control room instrumentation and other hardware to the above.

Terminology is defined in the broadest generic form to describe the various categories of these devices. It is not the intent of this standard to mandate the use of each type symbol for each occurrence of a generic device within the overall control system.

If, for example, a computer component is an integral part of a distributed control system, the use of the computer symbol would normally be an undesirable redundancy. If, however, a separate general purpose computer is interfaced with the system, the inclusion of the computer symbol may provide the degree of clarity needed for control system understanding.

This standard attempts to provide the users with defined symbolism and rules for usage, which may be applied as needed to provide sufficient clarity of intent. Not for resale.

This standard has been prepared as part of the service of ISA, The International Society of Automation, toward the goal of uniformity in the field of industrial automation. To be of continuing value, this standard should not be static but should be subject to periodic review.

The ISA Standards and Practices Department is aware of the growing need for attention to the metric system of units in general, and the International System of Units SI in particular, in the preparation of instrumentation standards.

The Department will endeavor to introduce SI-acceptable metric units in all new and revised standards, recommended practices, and technical reports to the greatest extent possible. It is the policy of ISA to encourage and welcome the participation of all concerned individuals and interests in the development of ISA standards, recommended practices, and technical reports. Participation in the ISA standards-making process by an individual in no way constitutes endorsement by the employer of that individual, of ISA, or of any of the standards, recommended practices, and technical reports that ISA develops.
