The work of preparing International Standards i

21、s 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 and non-governmental, in liaison with ISO, also take par

22、t 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 described in the ISO/IEC Directives, Part 1. In particul

23、ar 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 to the possibility that some of the elements of this

24、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 the ISO list of patent declarations received (see www.is

25、o.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, as well as information about ISOs adherence to the WT

26、O principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplementary informationThe committee responsible for this document is ISO/TC 213, Dimensional and geometrical product specifications and verification.This first edition of ISO 14638 cancels and replaces ISO/TR

27、14638:1995. ISO 14638 has been revised from the earlier ISO/TR 14638 document with the aim of clarifying the text and the definitions, in order to improve the usability of the document, and to revise the matrix where developments in ISO GPS have made this necessary.The main changes are as follows: T

28、he category of Global GPS standards has been removed, as it was not clearly distinguished from either fundamental or general GPS standards. Standards which were formerly classified as global GPS standards have either been withdrawn, or can be categorized as fundamental or general GPS standards. The

29、headings formerly used to describe the different chains in the matrix have been reduced. The headings for form of a line (independent of a datum) and form of a surface (independent of a datum) have been replaced with a single heading of form. The headings for form of a line dependent on a datum and

30、form of a surface dependent on a datum have been removed, because these are covered under orientation and location. The heading for datums has been removed from the matrix, because datums are not geometrical properties. Clause 4 now explains how the ISO GPS standard for datums is covered in the ISO

31、GPS matrix model. The headings for circular run-out and total run-out have been amalgamated into a single heading of run-out. The three chains for roughness profile, waviness profile and primary profile have been replaced with a single entry for profile surface texture.iv ISO 2015 All rights reserve

32、dBS EN ISO 14638:2015ISO 14638:2015(E) The heading for angle has been removed, as angles are covered under the headings of size and distance. The heading for radius has been removed, as this is covered under the headings of distance and form. The heading for edges has been removed, as edges are not

33、a geometrical property. An additional category of general GPS standards for areal surface texture has been added. An additional chain link for conformance and non-conformance has been added. The chain links have been given descriptive titles and are lettered. The chain link numbers used previously h

34、ave been removed. The GPS matrix now appears in only a single format for fundamental and general GPS standards. The lists of GPS standards has been removed from this document. An up-to-date list of ISO/TC 213 standards is maintained at the following location on the ISO website: http:/www.iso.org/iso

35、/home/store/catalogue_tc/catalogue_tc_browse.htm?commid=54924 distance; form; orientation; location; run-out; profile surface texture; areal surface texture; surface imperfections.The ISO GPS standards relating to each of these nine geometrical properties are grouped together in a series of nine cat

36、egories of standards (see 3.3). Each category may be further sub-divided into a number of more specific elements, and each of these specific elements identifies a chain of standards.For example, size is a geometrical property category. Size can then be subdivided into size of cylinders, size of cone

37、s, size of spheres, etc., each of which corresponds to a chain of standards.Angles are covered within the properties of size and distance, and radii are covered within the properties of distance and form.INTERNATIONAL STANDARD ISO 14638:2015(E) ISO 2015 All rights reserved 1BS EN ISO 14638:2015ISO 1

38、4638:2015(E)For each geometrical property, it is necessary to be able to define a specification for that property, it is necessary to be able to measure the property, and it is necessary to be able to compare the measurement with the specification. The GPS standards relating to these requirements ar

39、e defined as a series of seven links in each chain of standards (see 3.3).Some manufacturing processes, such as casting and welding (this list is non exhaustive), have requirements which are specific to that process. Standards which deal with specific processes may be grouped in further chains of st

40、andards.Some machine elements, such as screw threads and gears (this list is non exhaustive), have requirements which are specific to those machine elements. Standards which deal with specific machine elements are grouped in further chains of standards.Additional geometrical property categories and

41、chains may be added in the future to reflect developments in manufacturing and inspection processes, and other industry requirements.The standards, categories and chains of standards are arrayed in a matrix so that it is possible to clearly indicate the scope of application of each standard and the

42、relationships between standards.3 Structure3.1 GeneralThe ISO GPS standards can be arranged in a matrix of rows and columns. Each row in the matrix consists of one of the nine geometrical property categories, which may be further subdivided into chains of standards, and each column is described as a

43、 chain link. The scope of each ISO GPS standard can be illustrated on the ISO GPS matrix by showing which chain links (columns) in which geometrical property categories (rows) the standard applies to.3.2 Types of ISO GPS standards3.2.1 Fundamental ISO GPS standardsThese are ISO GPS standards which d

44、efine rules and principles which apply to all categories (geometrical property categories and other categories) and all chain links in the ISO GPS matrix.NOTE The category of Global ISO GPS standards has been removed from this document. ISO GPS standards which had previously been categorized as Glob

45、al ISO GPS standards are now categorized as either fundamental or general ISO GPS standards.3.2.2 General ISO GPS standardsThese are ISO GPS standards which apply to one or more geometrical property categories, and to one or more chain links, but are not fundamental ISO GPS standards.3.2.3 Complemen

46、tary ISO GPS standardsThese are ISO GPS standards which refer to specific manufacturing processes or to specific machine elements.3.3 The ISO GPS matrix3.3.1 Geometrical characteristic categoriesA geometrical property category consists of all the general ISO GPS standards which relate to a particula

47、r geometrical property, such as size, distance or location. There are currently nine geometrical property categories.In the ISO GPS matrix, each geometrical property category corresponds to a row in the matrix.2 ISO 2015 All rights reservedBS EN ISO 14638:2015ISO 14638:2015(E)3.3.2 Complementary cat

48、egoriesThe matrix includes two non-geometrical categories: the category of manufacturing processes and the category of machine elements.3.3.3 Chain of standardsA geometrical property category may be subdivided into chains of standards, each of which consists of all the general ISO GPS standards whic

49、h relate to a particular subdivision of a geometrical property category, such as size of cylinders, size of cones, and size of spheres.These subdivisions are not described in detail in this International Standard.The category of manufacturing processes may be sub-divided into chains of standards, corresponding to different types of manufacturing processes.The category of machine elements may be sub-divided into chains of standards, corresponding to different types of machine elements.Fur
