Scope
ISA5 oversees the work of working groups that produce standards, recommended practices, and technical reports for documenting and illustrating measurement and control instruments and systems suitable for all industries.
Purpose
To coordinate the activities of ISA5 working groups created to establish the means for documenting and illustrating the uses and functions of measurement and control instruments and systems. Additionally, ISA5 will ensure liaison between ISA5 working groups and other committees working in this area.
