National foreword This document (EN ISO 14638:2015) has been prepared by Technical Committee ISO/TC 213 “Dimensional and geometrical product specifications and ve
5、rification” in collaboration with Technical Committee CEN/TC 290 “Dimensional and geometrical product specification and verification” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was DIN-Normenausschuss Technische Grundlagen (DIN Standards Committee Technical
6、 Fundamentals), Working Committee NA 152-03-02 AA CEN/ISO Geometrische Produktspezifikation und -prfung. NOTE Users of this standard should note that, in ISO 14638:2015, “B.4” was skipped in the numbering and is now given as “B.5”. Amendments This standard differs from DIN V 32950:1997-04 as follows
7、: a) the category of global GPS standards has been removed, as it was not clearly distinguished from either fundamental or general GPS standards; b) the GPS matrix model has been completely revised (see National Annex NA for further details); c) the standard has been editorially revised.

ISO 14638 has been revised from the earlier ISO/TR 14638 document with the aim of clarifyi
9、ng 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: the category of global GPS standards has been removed, as it was not clearly distinguished from either
10、 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 Standards which were formerly classified as global GPS standards have either been withdrawn, or can be categorized as fundamental or general GPS standards; the headings formerly used to describe the different chains in the matrix have been reduced; the headings
11、 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 “form of a surface (dependent on a datum)” have been removed, because these are covered und
12、er “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 GPS matrix model; the headings for “circular run-out” and “total run-out” have be
13、en 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”; the heading for “angle” has been removed, as angles are covered under the headings of “size” and
14、 “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 a geometrical property; an additional category of general GPS standards for areal surface texture has been added; an addi
15、tional 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 have been removed; the GPS matrix now appears in only a single format for fundamental and general GPS standards; DIN EN IS
16、O 14638:2015-12 4 the lists of GPS standards have 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/home/store/catalogue tc/catalogue tc browse.htm?commid=54924 a diagram showing a version of
17、the matrix populated with references to individual ISO standards has been removed from this document. An online version of the matrix, with facilities to interrogate it, now appears on the ISO/TC 213 website at http:/ isotc213.ds.dk/, where it can be kept up-to-date; the rules which were formerly li
18、sted for the preparation of ISO GPS standards have been redrafted as a bulleted list of principles and recommendations; the “rule of unambiguity” has been re-written as the first principle in the list; the “rule of totality” has been removed, as it was not a rule but an aspiration; the “rule of comp
19、lementarity” has been removed because its meaning was not clear; the second principle has been added to avoid conflict between different GPS standards, which was the intention behind the former “rule of complementarity”; a third recommendation has been added, specifying the format of an informative
20、annex which will appear in all future GPS standards produced by ISO/TC 213. The annex explains how the individual GPS standard fits into the GPS matrix.

EN ISO 14638:2015 (E) 3 DIN EN ISO 14638:2015-12 IntroductionGeometrical Product Specification (ISO GPS) is the system used to define the geometrical requirements of workpieces in engineering specifications
37、, and the requirements for their verification.ISO GPS standards are the responsibility of ISO/TC 213. ISO GPS standards are used in conjunction with other standards for Technical Product Documentation (TPD), which is the responsibility of ISO/TC 10, to produce Technical Product Specifications (TPS).
38、This International Standard provides an overview of the structure of the ISO GPS system.The fundamental rules of ISO GPS given in ISO 8015 apply to this standard and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this standard, unless otherwise indica
39、ted.EN ISO 14638:2015 (E) 4 DIN EN ISO 14638:2015-12 1 ScopeThis International Standard is a fundamental ISO GPS standard. It explains the concept of Geometrical Product Specification (ISO GPS), and provides a framework to illustrate how current and future ISO GPS standards address the requirements
40、of the ISO GPS system.The framework is intended to be of use to users of ISO GPS standards, by illustrating the extent of the scope of the different standards, and showing how they relate to each other.The framework is also used for structuring the development of standards for GPS by technical commi
41、ttee ISO/TC 213.The full set of standards comprising the ISO GPS system is listed on the ISO/TC 213 website at h t t p :/www.iso.org/iso/home/store/catalogue_tc/catalogue_tc_browse.htm?commid=54924 distance; form; orientation; location; run-out; profile surface texture; areal surface texture; surfac
42、e imperfections.The ISO GPS standards relating to each of these nine geometrical properties are grouped together in a series of nine categories 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 c
43、hain of standards.For example, size is a geometrical property category. Size can then be subdivided into size of cylinders, size of cones, 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 wit
44、hin the properties of distance and form.EN ISO 14638:2015 (E) 5 DIN EN ISO 14638:2015-12 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 measuremen
45、t with the specification. The GPS standards relating to these requirements are 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. Standa
46、rds which deal with specific processes may be grouped in further chains of standards.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 i
47、n further chains of standards.Additional geometrical property categories and 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 po
48、ssible to clearly indicate the scope of application of each standard and the 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 f
49、urther subdivided into chains of standards, and each column is described as a 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 define rules and principles which apply to all categor
