This document has been prepared as part of the service of ISAThe Instrumentation, Systems, and Automation Society, toward a goal of uniformity in the field of instrumentation. To be of real value, this document should n

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
9、is further aware of the benefits to USA users of ISA standards of incorporating suitable references to the SI (and the metric system) in their business and professional dealings with other countries. Toward this end, this Department will endeavor to introduce SI-acceptable metric units in all new an
10、d revised standards, recommended practices, and technical reports to the greatest extent possible.

All rights reserved. 1 Scope Instrument devices with dedicated functionality may be specified using data-sheet-type, approved ISA specification forms. Thi
13、s 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,
14、 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. 2 Normative referen
15、ces ISA20.00.032001, Specification Forms for Process Measurement and Control Instruments, Part 3: Form Requirements and Development Guidelines. 3 Definitions For the purpose of this technical report, the following definition applies: 3.1 specification form: the document, or its electronic data equiv
16、alent, that details the statement of parameters or properties prescribing the design basis, construction, materials, and performance for an instrument to be supplied. 4 Application ISA specification forms may be used for the following different levels of device specification. 4.1 Operating parameter
17、s documentation Documentation of the operating parameters may be completed and endorsed independently of the hardware device selection and preliminary specification through the use of the separate form page. 4.2 Preliminary inquiry/quotation For a preliminary inquiry or quotation, the specifier and
18、vendor may agree on a minimum level of information. In this case, the specifier may mark with an asterisk (*) in the revision column of the Operating Parameters or Device Specification forms, any lines that the recipient of the specification form is requested to complete. 4.3 Traditional specificati
19、on Documentation of operating parameters required for sizing or selection analysis, and identification of the instrument properties that are pertinent to the development of a manufacturers model number, should be the minimum data provided on specification forms used to purchase instruments. 4.4 Conf
20、orming specification A complete specification ideally should include all relevant information about the main device and associated secondary devices that has been agreed to by the purchaser and supplier. In this case, the fully completed specification form can be used for the final documentation of
21、the instrument specifications. ISATR20.00.012007 14 Copyright 2011 ISA. All rights reserved. 5 Requirements 5.1 Three form parts ISA specification forms are generally comprised of three form parts for the following information organization: a) Operating Parameters forms are developed to document the
22、 process application and design conditions for communication to instrument specifiers and manufacturers. b) Device Specification forms are developed to provide the information to initially size and select a main device and the information to identify requirements for attached and directly associated
23、 devices. c) General or Special Requirements forms are developed to provide means for the specifier to identify general or special requirements that are applicable to the device, but need additional space beyond that available in the other two types of forms. 5.2 Form numbers and titles for Operatin
24、g Parameters forms A common form is developed for all devices sharing the same measured variable or final control element. Table A.1, annex A, identifies assigned categories, ISA form numbers, and titles. 5.3 Form numbers and titles for Device Specification forms Device Specification forms are group
25、ed and numbered based upon a device category code, the form part number, and an instrument function subcategory sequential number. Table A.2, annex A, identifies assigned device categories, ISA form numbers, and titles. 5.4 Form numbers and titles for General or Special Requirements forms A single f
26、orm is provided for the initial page of the General or Special Requirements forms. Table A.3, annex A, identifies the assigned ISA form number and title. 6 General sections of ISA specification forms 6.1 Specification identification section Operating Parameters, Device Specification, and General or
27、Special Requirements forms utilize the same specification identification field prompts. 6.2 Endorsements Endorsement identifications and status inference, such as originator, checker, approver, and origin date, should be independent throughout each form type. 6.3 Revision chronicle Identification of
28、 the three most recent entries recorded in the revision chronicle should be independent throughout each form type. 15 ISATR20.00.012007Copyright 2011 ISA. All rights reserved. 6.4 Component identification Identification of the instrument, such as primary tag number, description, line/equipment numbe
29、r, and reference drawing number, should be identical throughout each form type. 7 Classification and designation Hardware specification forms are based on specific hardware types as classified in annex A.
