The work of preparing International Standards is normally carried out through ISO technical commit
23、tees. 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 part in the work. ISO collaborates closely with the In
24、ternational 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 particular the different approval criteria needed for the d
25、ifferent types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall n
26、ot be held responsible for identifying any or all such patent rights.

29、 (according to the GPS rules)This corrected version of ISO 8062:2013 incorporates a change in 7.2.2, Figure 8.iv ISO 2013 All rights reservedPD CEN ISO/TS 8062-2:2013ISO/TS 8062-2:2013(E)IntroductionThis part of ISO 8062 is to be regarded as a complementary process-specific tolerance geometrical pro
30、duction specification (GPS) standard (see ISO/TR 14638). It influences chain links 1, 2 and 3 of the chain of standards on mouldings.The ISO/GPS Masterplan given in ISO/TR 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 80
31、15 apply to this document and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise indicated.For more detailed information about the relation of this part of ISO 8062 to other standards and the GPS matrix model, see Annex F.T
32、his part of ISO 8062 takes into account experiences with the application of previous standards (e.g. ISO 8062:1994, ASME Y14-8M:1996, and ISO 1101).The tolerancing methods in this part of ISO 8062 are not yet fully developed within the new approach of geometrical product specifications (GPS) accordi
33、ng to ISO 17450. The requirements for castings (mainly due to the uncertainty in the calculation of the shrinking of the casting) remain incompatible with the GPS standards. Therefore, this Technical Specification has been issued in order to gather further experience in the tolerancing of castings.I
34、t is intended that the next version of this document will include more realistic ways of calculating the nominal dimension dCof the final moulded part by elaborating GPS-conformant ways of combining linear dimensions and tolerance zones.This document is intended to cover all types of moulded parts.
35、However, most of the examples refer to castings.When the methods of this part of ISO 8062 are used in 3D models, provisions have to be made in order to distinguish between theoretically exact dimensions (TEDs) and linear and angular dimensions with plus/minus tolerances.

37、f moulded parts. It also gives rules and conventions for the indications of these requirements in technical product documentation and specifies the proportions and dimensions of the graphical symbols to be used.This part of ISO 8062 provides symbols which may be used to identify the relative complet
38、eness of the moulded features and parts. These graphical symbols should not be confused with the graphical symbols for surface texture according to ISO 1302, which are notably larger.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and a
