Instrument devices with dedicated functionality may be specified using data-sheet-type, approved ISA specification forms. This technical report does not address system specifications such as shared control and shared display devices, where extensive use of functionality or performance specifications is required.

This technical report lists the ISA specification forms by form part category, measured or initiating variable, readout, or final control device categories, and form number. A form numbering system has been implemented that identifies the form categories, device function grouping, and page number. The form number, title, and development status is listed for each proposed or approved form.
