13、d ISO (the International Organization for Standardization) is a worldwide federation of national stan- dards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a techni
14、- cal committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electro technical Commission (IEC) on all matters o
15、f electro technical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Stan- dards adopted by the technical committees are circulat
16、ed to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other t
17、ypes of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between techni- cal experts in an ISO working group and is accepted for publication if it is approved by more than 50% of the members of the parent committee casting a vote; an ISO Technical Specifi
18、cation (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed every three years with a view to deciding whether it can be trans- formed int
19、o an International Standard. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TS 15926-4 was prepared by Technical Committee ISO/TC 184, Industria
20、l automation systems and integration, Subcommittee SC 4, Industrial data. ISO 15926 consists of the following parts, under the general title Industrial automation systems and integration Integration of life-cycle data for process plants including oil and gas production facili- ties: Part 1: Overview
21、 and fundamental principles Part 2: Data model Part 4: Initial reference data Technical Specification The following parts are under preparation: Part 3: Ontology for geometry and topology Technical Specification Part 7: Implementation methods for data exchange and integration Technical Specification
22、 A complete list of parts of ISO 15926 is available from the Internet: ISO/TS 15926-4:2007(E) ISO 2007 All rights reserved v Introduction ISO 15926 is an International Standard for the representation of process industries facility life-cycle information. This representation is specified by a generic
23、, conceptual data model that is suitable as the basis for implementation in a shared database or data warehouse. The data model is designed to be used in conjunction with reference data, i.e. standard instances that represent information common to a number of users, production facilities, or both. T
24、he support for a specific life-cycle activity depends on the use of appropriate reference data in conjunction with the data model. ISO 15926 is organized as a series of parts, each published separately. This part of ISO 15926 speci- fies the initial set of reference data items. The structure of ISO
25、15926 is as follows: ISO 15926-1 provides an overview of ISO 15926; ISO 15926-2 contains a generic, conceptual data model that supports representation of all life- cycle aspects of a process plant; ISO/TS 15926-3 1contains a reference data library for geometry and topology; ISO/TS 15926-4 contains a
26、 reference data library for physical objects, activities, properties and other reference data necessary to record information about a process plant; ISO 15926-5 2specifies the procedures to be followed for the maintenance of the reference data library ISO/TS 15926-4; ISO 15926-6 3specifies the infor
27、mation that is recorded for reference data items of ISO/TS 15926-4; ISO/TS 15926-7 4specifies implementation methods for the integration of distributed systems. 1To be published. 2Under preparation. 3Under preparation. 4To be published.

28、his part of ISO 15926 specifies the initial set of core reference data items which can be used to re- cord information about process plants, including oil and gas production facilities. The following are within the scope of this part of ISO 15926: core classes for process plants, including oil and g
29、as production facilities; NOTE 1 Reference data items can be core classes, de facto classes, commodity classes and manufac- tured product classes. Reference data items can also be standard classes or proprietary classes. The terms for the different types of class are defined in 3.2. A discussion abo
30、ut the different types of classes is contained in Annex D. the unique name for each reference data item; the definition of each reference data item; subclass and classification relationships between reference data items; NOTE 2 Each reference data item that is a class is directly or indirectly a sub
31、class of an entity in ISO 15926-2. the entity within ISO 15926-2 which can be used to record each reference data item. The following are outside the scope of this part of ISO 15926: data requirements for additional reference data; a numeric identifier for each reference data item; NOTE 3 Numeric ide
32、ntifiers may be assigned by a registration authority. the procedures to be followed for registration and maintenance of additional reference data. NOTE 4 A core class defined by this part of ISO 15926 can be used by ISO 15726-2, ISO/TS 15926-7 or ISO 10303-221. ISO 2007 All rights reserved 1 TECHNIC

37、10303-1 For the purposes of this document, the following terms and definitions given in ISO 10303-1 apply. They are repeated below for convenience. 3.1.1 data representation of information in a formal manner suitable for communication, interpretation, or proc- essing by human beings or computers 3.1
38、.2 information facts, concepts, or instructions 3.2 Terms defined in ISO 15926-1 For the purposes of this document, the following terms and definitions given in ISO 15926-1 apply. They are repeated below for convenience. 3.2.1 class category or division of things based on one or more criteria for in
39、clusion and exclusion NOTE 1 A class need not have any members (things that satisfy its criteria for membership). NOTE 2 Because the spatio-temporal paradigm is used to define individuals in this part of ISO 15926, all classes are non-well-founded sets. These are explained in ISO 15926-2:2003, D.2.4
40、 3.2.2 commodity product class manufactured product class whose members conform to open agreed standards ISO/TS 15926-4:2007(E) 2 ISO 2007 All rights reserved NOTE Commodity product classes have sufficient characterization to indicate suitability of use. They are specializations of one or more de fa
41、cto classes, standard classes, or both. The resulting specification is non- proprietary, as no one organization controls it. EXAMPLE The type of light bulb known as 60 W 230 V E27 is a commodity class. 3.2.3 core class class that is a commonly used subdivision corresponding to terms used in common l
42、anguage NOTE The conditions for membership are often not formally defined; understanding of the class may be conveyed by example. EXAMPLE Pipe, floor, pump, and light bulb are all core classes. 3.2.4 de facto class class corresponding to common natures that are widely recognized but not formally agr
43、eed or defined NOTE De facto classes may be formalized by international, national, or industry agreement. EXAMPLE 1 A manufacturer may choose to make a product of similar specification to that of another manufacturer in order to compete for the market share by choosing to conform to some characteris
44、tics of the other product. EXAMPLE 2 3.5” floppy disk and HB pencil are de facto classes. 3.2.5 manufactured product class class whose members are individuals produced by a manufacturing process NOTE 1 The members of a manufactured product class may be discrete or may be batches or continuous flows,
45、 such as process fluids. NOTE 2 A manufactured product class may correspond to a specification that has not been realized, such as a product specification for which no products have been made. EXAMPLE 1 “Lightbulbs 60 W 230 V E27” is an example of a manufactured product class whose members are discr
46、ete. EXAMPLE 2 “BS4040 Leaded Petrol” is an example of a manufactured product class whose members are continuous. 3.2.6 proprietary class class whose specification for membership is owned, controlled, or protected by an organization and is not generally available outside that organization 3.2.7 prop
47、rietary product class class that is a manufactured product class and a proprietary class NOTE Proprietary product classes are specializations that depend on rules of inclusion and exclusion some of which are controlled in a closed way. This means that some aspects of the specification can be arbitra
48、rily changed. Many proprietary product classes are specializations of commodity product classes, de facto classes, or both, where the additional restrictions reflect design or manufacturing details that the manufacturer uses to differentiate his product from others of the same general type. ISO/TS 1
49、5926-4:2007(E) ISO 2007 All rights reserved 3 EXAMPLE 1 A product specification that is owned by a commercial organization, and is marketed under and protected by a registered trade name, is the basis for a proprietary product class. EXAMPLE 2 Lightbulbs 60 W 230 V E27 manufactured by Phillips are members of a proprietary product class. 3.2.8 reference data process plant life-cycle data that represents information about classes or individuals which are com- mo
