20、8:2018ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards 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 whic

21、h 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 part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all ma

22、tters 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 particular the different approval criteria needed for the different types of ISO documents should be noted. This d

23、ocument 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all

24、 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.iso.org/patents).Any trade name used in this document is information given for the convenience of users and

25、does not constitute an endorsement.For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Tr

26、ade (TBT) see the following URL: www.iso.org/iso/foreword.html.This document was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product specifications and verification.This third edition cancels and replaces the second edition (ISO 5458:1998), which has been technically revi

27、sed.The main changes to the previous edition are as follows: exception from the independency principle removed according to ISO 8015; rules harmonized to align with ISO 1101; unstated rules in ISO 5458:1998 removed; concept of “pattern” to control all types of geometrical features introduced more ge

28、nerically, rather than applying it only with position symbol.iv ISO 2018 All rights reservedBS EN ISO 5458:2018ISO 5458:2018IntroductionThis document is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO 14638). It influences chain links A, B

29、and C for form, orientation and location.The ISO/GPS matrix model given in ISO 14638 gives an overview of the ISO/GPS system of which this document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rules given in ISO 14253-1 apply to specif

30、ications made in accordance with this document, unless otherwise indicated.For more detailed information of the relation of this document to the GPS matrix model, see Annex F.ISO 1101 and other relevant documents, such as those dealing with the least and maximum material requirement (ISO 2692) and t

31、he datum system (ISO 5459), should be taken into consideration when using this document.This document provides rules for the tolerancing of a tolerance zone pattern, i.e. a collection of tolerance zones constrained to each other with or without reference to a datum system which does not lock all deg

32、rees of freedom.For the presentation of lettering (proportions and dimensions), see ISO 3098-2.All figures in this document for the 2D drawing indications have been drawn in first-angle projection with dimensions and tolerances in millimeters. It should be understood that third-angle projection and

33、other units of measurement could have been used equally well without prejudice to the principles established.Annexes A and B provide more information on the changes in practice and differences between this document and ISO 1101 on one hand and ISO 5458:1998 on the other hand.

35、lated technical drawing specification; these illustrations are not fully dimensioned and toleranced, showing only the relevant general principles. In particular, many illustrations do not contain filter specifications. As a consequence, the illustrations are not a representation of a complete workpi

36、ece, and are not of a quality that is required for use in industry (in terms of full conformity with the standards prepared by ISO/TC 10 and ISO/TC 213), and as such are not suitable for projection for teaching purposes.1 ScopeThis document establishes complementary rules to ISO 1101 to be applied t

37、o pattern specifications and defines rules to combine individual specifications, for geometrical specifications e.g. using the symbols POSITION, SYMMETRY, LINE PROFILE and SURFACE PROFILE, as well as STRAIGHTNESS (in the case where the toleranced features are nominally coaxial) and FLATNESS (in the

38、case where the toleranced features are nominally coplanar) as listed in Annex C.These rules apply when a set of tolerance zones are grouped together with location or orientation constraints, through the use of the CZ, CZR or SIM modifiers.This document does not cover the use of the pattern specifica

39、tions when the least and maximum material requirement is applied (see ISO 2692).This document does not cover the establishment of common datum (see ISO 5459) based on pattern features.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their co
