This update includes 27 new specification forms in 2004-2006. These new expanded specification forms have been modified extensively to cover operating parameters and expand the form content beyond the limitations of the original ISA-20-1981 forms. Many of the forms represent new devices not previously covered by the original forms. Separate forms are provided for operating parameters, device specifications, and general requirements. This technical report applies to all processes of development and use of ISA specification forms for process measurement and control instruments. It does not address system specifications such as shared control and shared display devices, where extensive use of functionality or performance specifications is required. ISA-20.00.03-2001, Specification Forms for Process Measurement and Control Instruments Part 3: Form Requirements and Development Guidelines, is included with this Technical Report. Supplementary picklists for each form, available for free viewing and/or printing through the following links, provide input guidance. The picklists are arranged into seven major categories, as follows: Control or Regulator Device Picklists Flow Device Picklists Level Device Picklists Pressure or Differential Pressure Device Picklists Receiver Device Picklists Temperature Device Picklists Operating Parameter Picklists
