21、dies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental an

22、d non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are de

23、scribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn

24、 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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on th

25、e ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment,

26、 as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplementary informationThe committee responsible for this document is ISO/TC 10, Technical product documentation.This second edition cancels and replaces th

27、e first edition (ISO 16792:2006), which has been technically revised mainly to incorporate the technical changes in ISO 1101:2012 and ISO 5459:2011. Clause 12 on indication for welds and Clause 13 on indications for surface texture have been added. A new informative annex on classification codes has

28、 also been added.vi ISO 2015 All rights reservedBS ISO 16792:2015ISO 16792:2015(E)IntroductionEvery effort was made during the preparation of the first edition of this International Standard, adapted from ASME Y14.41:2012, to apply existing requirements developed for two-dimensional (2D) presentatio

29、n equally to the output from three-dimensional (3D) models. Where new geometrical product specification (GPS) rules have proved essential, these have been drafted with a view to their being equally applicable to both 2D and 3D. Therefore, in order to maintain the integrity of a single system, these

30、new rules are being incorporated in the relevant existing ISO standards for cross-reference. Application examples have been included where, due to the specific requirements of 3D modelling, additional guidance was deemed beneficial.It is recognized that there is a need to support drawings in conjunc

31、tion with 3D models now and for the foreseeable future. This need has been addressed in this International Standard through the definition of the two methods for documenting digital models and specification of requirements to ensure that the information in a data set is consistent between the model

32、and the drawing.The figures in this International Standard are intended only as illustrations to aid the user in understanding the practices elaborated in the text. In some cases, figures show a level of detail as needed for emphasis; in others, they are only complete enough to illustrate a concept

33、or facet thereof. The absence of figures has no bearing on the applicability of the specified requirement or practice.In order to comply with the requirements of this International Standard, actual data sets shall meet the content requirements set forth in its text.Most figures are illustrations of

34、models in a 3D environment. Figures illustrating drawings in digital format include a border.Text in uppercase letters used in the figures are intended to appear in digital product definition data, or data sets, while that in lowercase letters is for information only and is not intended to appear in

35、 data sets. ISO 2015 All rights reserved viiBS ISO 16792:2015BS ISO 16792:2015Technical product documentation Digital product definition data practices1 ScopeThis International Standard specifies requirements for the preparation, revision, and presentation of digital product definition data, hereaft

36、er referred to as data sets. It supports two methods of application: model-only and model and drawing in digital format. Its structure presents requirements common to both methods followed by clauses providing for any essential, differing requirements for each method. Additionally, its use in conjun

37、ction with computer-aided design (CAD) systems could assist in the progression towards improved modelling and annotation practices for CAD and engineering disciplines, as well as serving as a guideline for IT engineers.The aspects specified in this International Standard refer mainly, but not exclus

38、ively, to requirements that differ or are additional to those provided in existing, related standards. Where no such requirements are identified, it is safe to assume that the appropriate existing ISO standards are instead applicable.2 Normative referencesThe following referenced documents are indis
