DIN EN ISO 17450-2:2013-04 EN ISO 17450-2:2012 (E) 3IntroductionThis part of ISO 17450 is a Geometrical Product Specifications (GPS) standard and is to be regarded as a global GPS standard (see ISO/TR 14638). It influences al
28、l chain links in all chains of standards in the general GPS matrix.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 8015 apply to this document and the default decision rules given in
29、ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise indicated.For more detailed information on the relationship of this part of ISO 17450 to other standards and to the GPS matrix model, see Annex C.This part of ISO 17450 covers several fundamental issues commo
30、n to all the GPS standards developed by ISO/TC 213 and, by presenting GPSs basic tenets and specification and verification processes, explains some of the underlying ideas and indicates the starting point for the standards developed by this technical committee.It is pointed out that these ideas and,
31、 for that matter, all the other ideas and concepts applied by ISO/TC 213 are subject to development and refinement, as the TCs recognition and understanding of them further evolves during its ongoing standards work.DIN EN ISO 17450-2:2013-04 EN ISO 17450-2:2012 (E) 41 ScopeThis part of ISO 17450 def

39、TE 1 Specification operations are used as part of a specification operator (3.2.3), in order to define a GPS requirement for a work-piece (product or component).NOTE 2 A specification operation is a theoretical concept.EXAMPLE 1 Association of a minimum circumscribed cylinder in the specification of
40、 the diameter of a shaft.EXAMPLE 2 Filtration by a Gaussian filter in the specification of a surface texture requirement.3.1.2default specification operationspecification operation (3.1.1) which is applied to a basic GPS specification (3.4.4) in the absence of any additional information or modifierN
41、OTE 1 The default specification operation may be a global default (ISO default), company default or drawing default specification operation.NOTE 2 The default specification operation depends on the context in which the default specification operator is applied.EXAMPLE 1 Evaluation of a two-point dia
42、meter in the specification of the diameter of a shaft using the default indication 30 0,1.EXAMPLE 2 Filtration by a Gaussian filter (default filter) with the default cut-off length given in ISO 4288 in the specification of Ra for a surface.3.1.3special specification operationspecification operation
43、(3.1.1) which is applied to a basic GPS specification (3.4.4) to change or modify a default specification operation (3.1.2) for this basic GPS specification with additional information or one or more modifiersEXAMPLE 1 The association of a minimum circumscribed cylinder in the specification of the d
44、iameter of a shaft, when the modifier symbol, , for envelope requirement, is used (see ISO 14405-1).EXAMPLE 2 The filtration by a Gaussian filter (default filter) with a special cut-off length of 2,5 mm in the specification of Ra for a surface, when the appropriate indication is used to override the
45、 default rules in ISO 4288.3.1.4actual specification operationspecification operation (3.1.1) which is indicated implicitly (in the case of a default specification operation) or explicitly (in the case of a special specification operation) in a GPS requirement indicated in the technical product docu
46、mentation under considerationNOTE An actual specification operation can be: indicated implicitly by an ISO basic GPS specification (3.4.4), or; indicated explicitly by a GPS specification element (3.4.1), or; omitted when the specification operator is not complete.EXAMPLE 1 Evaluation of a two-point
47、 default diameter in an actual specification operation, such as when the specification 30 0,1 is used (see ISO 14405-1).EXAMPLE 2 Filtration by a Gaussian filter (default filter) with a special cut-off length of 2,5 mm, and the calculation of a surface texture requirement using the Ra algorithm, are
48、 two actual specification operations, when the specification indicates Ra 1,5 with a 2,5 mm filter.DIN EN ISO 17450-2:2013-04 EN ISO 17450-2:2012 (E) 63.1.5verification operationoperation which is implemented in the form of a measurement, or by means of a measurement apparatus, or a combination of these, which corresponds to an actual specification operation (3.1.4)NOTE 1 Verification operations are used in the geometrical field of mechanical en
