ISA standards play a major role in the work of instrumentation and automation professionals. Many ISA standards have been recognized by the
American National Standards Institute (
ANSI) as approved American National Standards.
Standards committees ISA standards are developed using a
consensus-based model employing volunteer standards committees of automation professionals from across industries. The
ANSI standards development model is used with standards committees having the characteristics of Openness, Lack of Dominance, Balance, Consensus and a Right of Appeal. All ISA standards processes are overseen by the ISA Standards & Practices Board. As of 2025, there were more than 3500 participating individuals on ISA standards committees, from over 40 countries. ISA standards cover a wide range of concepts of importance to instrumentation and automation professionals. ISA has standards committees for symbols and
nomenclature used within the industry, safety standards for equipment in
non-hazardous and hazardous environments, communications standards to permit interoperable equipment availability from several manufacturers, and additional committees for standards on many more technical issues of importance to the industry. An example of one significant ISA standard is the ANSI/ISA-50.02
Fieldbus Standard for Use in Industrial Control Systems, which is a product of the ISA-50 Signal Compatibility of Electrical Instruments committee. Another significant ISA standard family is the batch processing standards of ANSI/ISA-88.00.01
Models and Terminology, ANSI/ISA-88.00.02
Data Structures and Guidelines for Languages, and ANSI/ISA-88.00.03
General and Site Recipe Models and Representation, which are products of the ISA-88 Batch Control committee. Other standards developed by ISA include:
ISA100.11a is for testing and certification of wireless products and systems. This standard was approved by the
International Electrotechnical Commission (IEC) as a publicly available specification, or PAS in September 2011.
ISA95 is an international standard for developing an automated interface between enterprise and control systems. As of 2025, the Society has over 135 published standards, recommended practices, and technical reports.
Security Standards for Automation and Control Systems The International Society of Automation also produces the
ISA-62443 standards as part of the
information security standards. The security of private industries and governmental installations are often dependent on the reliable functioning of an
Industrial control system. This is a highly debated subject that has considerable importance for the security of the
critical infrastructure of any country. For example: International Society of Automation security standards are mentioned on the United States Computer Emergency Response Team website. The ISA has formed the ISA Security Compliance Institute to promote and designate cyber-secure products and practices for industrial automation suppliers and operational sites. ==Conferences and Events==
