13、ONS FOR DATA ELEMENT TYPES GUIDELINES FOR PRODUCT COMMITTEES FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co

14、-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred

15、to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in thi

16、s preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internationa

17、l consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable ef

18、forts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publica

19、tions transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. In

20、dependent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) N

21、o liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs

22、 (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct applicat

23、ion of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare Internatio

24、nal Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or

25、where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC 62768, which is a t

26、echnical specification, has been prepared by IEC technical committee 3: Information structures, documentation and graphical symbols. 4 TS 62768 IEC:2012(E) The text of this technical specification is based on the following documents: Enquiry draft Report on voting 3/1079A/DTS 3/1101/RVC Full informa

27、tion on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unch

28、anged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual

29、 version of this publication may be issued at a later date. TS 62768 IEC:2012(E) 5 PREPARATION AND PROCESSING OF SOURCE DEFINITIONS FOR DATA ELEMENT TYPES GUIDELINES FOR PRODUCT COMMITTEES 1 Scope This Technical Specification specifies how product committees, including committees producing horizonta

30、l standards, intending to submit Data Element Types (DETs) for inclusion in the IEC Component Data Dictionary (IEC CDD), should specify the source descriptions in their own standard; and specify the information to be sent to SC3D for inclusion in IEC CDD. 2 Normative references The following documen

31、ts, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 61360-1:2009, Standard d

34、 Terms and definitions For the purposes of this document, the following terms and definitions apply. NOTE Words shown in italics in a definition in Clause 3 are defined as terms elsewhere in the clause. 3.1 attribute any one of the properties to describe an entity, possibly involving one or more oth

35、er entities SOURCE: IEC 61360-1:2009, 2.12 Note 1 to entry: In this context “entity” refers to a “data element type”, and “property” refers to a parameter suitable for the description of this. _ 1To be published. 2To be published. 6 TS 62768 IEC:2012(E) 3.2 (characteristic) property defined paramete

36、r suitable for the description and differentiation of objects Note 1 to entry: The term (characteristic) property (of an object) is not identical with the term data element type used in IEC 61360. A data element type is a unit of data for which the identification, description and value representatio

37、n have been specified in the context of a dictionary, while the term (characteristic) property is used for an occurrence of such a data element type in the context of a specification of an object. This distinction makes it possible to qualify a property in an object specification and still refer to

38、the same data element type definition in the dictionary.

40、lled by a product or group of products to establish its fitness for purpose Note 1 to entry: A product standard may include, in addition to the fitness-for-purpose requirements, directly or by reference, aspects such as terminology, sampling, testing, packaging and labelling and, sometimes, processi

41、ng requirements. Note 2 to entry: A product standard can either be complete or not, according to whether it specifies all or only a part of the necessary requirements. In this respect, one may differentiate between standards such as dimensional, material and technical delivery standards. SOURCE: ISO

42、/IEC Guide 2:2004, 2.4 4 General 4.1 Background information General guidelines regarding the specification of product properties are provided in ISO/IEC Guide 77, all parts. Information on the description of Data Element Types (DETs) is provided in the horizontal standard IEC 61360-1. A dictionary i

43、nformation model using EXPRESS modeling language is provided in the horizontal standard IEC 61360-2. Information on the application of DETs for specification of characteristic properties of products is provided in IEC 62569, all parts. TS 62768 IEC:2012(E) 7 4.2 Cooperation and responsibilities Data

44、 Element Types (DETs) are used for computer interpretable specification of characteristic properties of products, systems and components. “Computer interpretable” indicates that formal requirements have to be fulfilled, from information technological view, with regard to way the standardization of D

45、ETs is carried out. The IEC Component Data Dictionary (IEC CDD, IEC 61360-4) is the IEC repository for DETs. It is managed by SC3D Product properties and classes and their identification, of TC3 Information structures, documentation and graphical symbols. SC3D is responsible for carrying out the las

46、t part of the standardization procedure that ultimately leads to the inclusion of a DET in this repository. This includes all required formal checks of the DET, mentioned above. The beginning of the standardization process is the task of those committees that wish to have their DETs included in the

47、IEC CDD. Experts involved in product committees have knowledge of the actual product properties (but often limited interest in information technology); experts involved in SC3D have necessary knowledge of how to handle the information (but cannot possibly have complete knowledge of all product areas

48、). The standardization of DETs is therefore by necessity a cooperative task between the SC3D and the actual committee. The committee is responsible for the supply of adequate source descriptions for the DETs for further processing by SC3D. In many cases is it wise to set up a specific MT to support

49、the cooperation. The committee supplying information for publication in the IEC CDD shall be aware of the following statement: By submitting content for storage, discussion, or publication in an IEC publication in database form, the proposer declares that the submitted content may be exploited according to the rules stated in the relevant license statement. No economic rights (such as copyright or intellectual property rights) 1shall apply that restrict the above use of the submit
