To be of real val
4、ue, this document should not be static, but should be subject to periodic review. Toward this end, the Society welcomes all comments and criticisms, and asks that they be addressed to the Secretary, Standards and Practices Board, ISA, 67 Alexander Drive, P. O. Box 12277, Research Triangle Park, NC 2
5、7709, Telephone (919) 549-8411, e-mail: standardsisa.org. 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 Dep
6、artment is further aware of the benefits to U.S.A. 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
7、 all new and revised standards to the greatest extent possible. The Metric Practice Guide, published by the Institute of Electrical and Electronics Engineers as ANSI/IEEE Std. 268-1982, and future revisions, will be the reference guide for definitions, symbols, abbreviations, and conversion factors.
8、 Certain metric units that are not a part of the SI system are in common accepted use. This recommended practice uses bar as a pressure measurement that is convertible to kilopascals by multiplying by 100.It is the policy of ISA to encourage and welcome the participation of all concerned individuals
9、 and interests in the development of ISA standards. Participation in the ISA standards-making process by an individual in no way constitutes endorsement by the employers of the individual, of the Instrument Society of America, or of any of the standards that ISA develops.The information contained in
10、 the preface, footnotes, and appendices is included for information only and is not a part of this recommended practice.This recommended practice is one of a series that constitutes the control center standard, ISA-S60. The individual sections provide continuity of presentation, convenience of refer
11、ence, and flexibility of revision. The complete standard consists of the following sections:SECTION TITLE SCOPERP-60.1 Control Center Facilities Guide for preparation of engineeringdesigns and specifications for controlcenter facilities.dRP60.2* Control Center Design Design methods and terminologyGu

24、nts may be the user, designer, engineering contractor, control center fabricator, and instrument or device manufacturer. Since the extent of control center documentation is variable, it is recommended that a specific individual be assigned the responsibility and authority to determine which document
25、s are required, the quantity required, who will supply them, and the scheduled issue date.Changes to the documentation should be itemized to show who changed what, when, and why.4 SpecificationsControl center specifications should describe, in writing, every item that cannot be better described or d
26、efined graphically on drawings. By the time a control center design effort reaches the specification stage, many engineering decisions that contribute to the conceptual design of the specific control center have already been made.It is recommended that a conceptual design and functional description
27、be included for the benefit of those reading the specification to gain an insight that cannot be gleaned from the usual terse technical content. This information is for clarification only, and it should be noted that it is not a part of the bidding document.The specification must clearly define resp
28、onsibilities with respect to detail design of the control center, the equipment, and all subsystems and their components. Detailed instructions may be required for design approval procedures whereby the responsible party receives authority to proceed with the purchase and fabrication up to the next
29、approval stage.When manufacturing progress reports are required, their contents should be clearly defined in the specification. Photographs of manufacturing progress may be used to support the usual written reports.Approved revisions of the specification should be issued immediately while the revisi
30、ons are still fresh in memory; otherwise, important changes, even conceptual design changes, can be forgotten.4.1 Codes, standards, and practices. Compliance with national, state, and local regulations may require conformance with various specific codes. Good engineering practice also requires con-f
31、ormance with well established standards and practices. A partial list of possible applicable codes and standard practices is listed in Appendix A.Specification reference to a published standard in full, although better than no reference at all, usually is too general and may even lead to confusion b
32、ecause of multiple methods recommended by many standards. It is more precise to refer to specific paragraphs of the standard and describe how that paragraph applies (or is to be modified) for the specific control center.4.2 Instrument and equipment lists. Instruments and equipment that will be insta
33、lled in control centers are of three basic types:1) Tagged items (see 4.2.1);2) Untagged items (see 4.2.2);3) Fabricated items (see 4.2.3).12 ISA-RP60.4-1990The specification should include a list of instruments and equipment. It also should indicate who is to supply the instruments and equipment.4.
34、2.1 Tagged items4.2.1.1 The following are examples of tagged items:1) Indicating controllers;2) Recorders;3) Converters;4) Transducers;5) Receiver switches;6) Push buttons, status lights, selector switches, etc.;7) Prefabricated interconnecting cables.The list of tagged items should be specific and
35、identify every individual significant item that must be handled separately. Tagging will permit tracking items enroute and ease in recovery from storage. If an item is shipped to a fabricator in multiple pieces, each piece should be uniquely identified even if differentiated only by a suffix, e.g.,
36、FY123-A and FY-123-B. Refer to ANSI/ISA-S5.1-1984 for instrument tagging.4.2.1.2 The following are examples of information required to properly list tagged items:1) Tag number;2) Item function (e.g., MV/I converter);3) Item data sheet reference;4) Item purchase order reference;5) Manufacturer;6) Mod
37、el number;7) Service description;8) Drawing number of P9) Loop drawings;10) Serial number (if assigned);11) Location (e.g., Aux. Cab. No. 5).A typical instrument and equipment list is furnished in Appendix B.4.2.2 Untagged items4.2.2.1 Untagged items are interchangeable and can be tagged as a group.
38、 The following are examples of untagged items:1) Instrument shelves;2) Instrument racks;3) Computers and associated peripherals;ISA-RP60.4-1990 134) VDT displays, video station (VDT, keyboard, etc.);5) Power supplies, including uninterruptible power supply (UPS) systems;6) Terminal blocks;7) Relays;
39、8) Clocks;9) Programmable controller (if only one);10) Multiplexers;11) Input/output (I/O) racks.4.2.2.2 Untagged instruments and equipment are more difficult to control and track due to the lack of a unique identifying tag number. It is recommended that a general identification number be assigned t
40、o a group of like items. Equipment, once installed in the control center, may be assigned a unique tag number.The information required to properly identify untagged items may include the following:1) General identification;2) Purchase order reference;3) Functional description;4) Quantity;5) Manufact
41、urer;6) Model number;7) Serial number (if assigned).4.2.3 Fabricated items. The following are examples of fabricated items:1) Control center sections;2) Consoles;3) Auxiliary relay and equipment racks.It is recommended that fabricated items be assigned a general identification number. An ideal “brea
42、k point” for numbering fabricated items is at each break. This facilitates panel shop tracking and identification for shipment to the installation site. Also, this facilitates location of the control center components on the control center facility plan drawing.4.2.4 Shipping and receiving reports.
43、The instrument and equipment list should make provision for logging the shipment and receipt of the equipment and certified drawings. The control center manufacturer should be instructed in the method by which shipment and receipt ofequipment is reported to the user or purchaser. Instructions also s
44、hould be provided to cover damaged equip-ment.4.3 Graphics. ISA-S5.5 establishes symbols used on dynamic displays such as VDTs.Documentation for graphic displays should be sufficient to allow future modification of the displays using original materials, methods, symbols, and colors. Materials, when
45、not the fabricators standard, should be documented by listing manufacturer, material type, specification 14 ISA-RP60.4-1990number, thickness, surface finish, colors, etc., as applicable. Methods should be documented by listing the method of cutting the material, edge preparation, surface preparation
46、, and adhesive or fastener specification. The recommended adhesive solvent should also be listed.4.3.1 Symbols. Graphic symbols should be documented on dimensioned or scaled drawings. A list of all symbol engravings should be included. Colors should be documented by listing a man-ufacturers color or
47、 recognized standard color name or number.4.4 Identification. Identification for control centers is described in ISA-RP60.6, Nameplates, Labels, and Tags for Control Centers.Control center specifications should identify what items to tag, what materials to use, and the method of attachment for the t
48、ags. The identification plate material, color, surface finish, etc., should be specified. Methods of engraving, letters or numbers, and size of nameplates, as well as size and color of engraving, printing, etc., also should be included. A list of all nameplate engraving data should be included.4.5 C
49、onstruction. Additional documentation will be required in those cases where special vibration conditions must be considered, i.e., seismic or other vibrations. High humidity, limited accessibility, and other construction considerations will also require special documentation.4.5.1 Modularity and shipping sections. The modularity of a finished control center usually is dictated by shipping and handling considerations and intended future control center use. The signal interconnections between modular sections should be documented sufficiently for proper reconnection after install
