38、erived) of workpieces, which are toleranced features in GPS specifications (dimensional, geometrical, or surface texture specifications). This part of ISO 17450 defines default geometrical features used to define GPS characteristics.2 Normative referencesThe following documents, in whole or in part,

41、 the purposes of this document, the terms and definitions given in ISO 17450-1, ISO 22432, ISO 25378 and the following apply.3.1opposing point paircollection of two points established simultaneously, the separation of which is a local size of a feature of sizeNote 1 to entry: The distance between th

42、e two points constituting an opposing point pair is a two point size (see ISO 14405-1).Note 2 to entry: In the case of a feature of size defined as “two opposed planes”, the median point of the two points constituting an extracted opposing point pair belongs to its median extracted surface.3.2elemen

43、tary toleranced featuresmallest part of a complete geometrical feature for which a GPS characteristic is definedEXAMPLE 1 For an unrestricted flatness specification, a global GPS characteristic is defined for the complete integral feature, which in this case is an elementary toleranced feature.EXAMP

44、LE 2 For a straightness specification, a local GPS characteristic may be defined for each line feature in a given direction in the complete integral feature. Each of these line features is the intersection between a planar feature and the complete integral feature and is an elementary toleranced fea

45、ture. The complete integral feature is the toleranced feature.EN ISO 17450-3:2016 (E) DIN EN ISO 17450-3:2016-12 6 3.3toleranced featurecomplete toleranced featureset of one or more geometrical features, for which a GPS characteristic is defined or a collection of elementary toleranced featuresNote

46、1 to entry: “Toleranced feature” without a qualifier is a complete feature, not an elementary feature.Note 2 to entry: A toleranced feature is a set of geometrical features on which a GPS specification is defined.3.4median centrecentre point calculated as the centre of an opposing point pairNote 1 t

47、o entry: A centre of an associated sphere is a directly associated median point (see ISO 22432 and 5.3.2.1) and not a median centre.4 GeneralA GPS characteristic (see ISO 25378) is a basic characteristic (an intrinsic characteristic or a location or an orientation situation characteristic). The size

48、 of a deviated feature (see ISO 22432), which is nominally a feature of size is an intrinsic characteristic (see ISO 17450-1), which is used for dimensional specification (see ISO 14405). The value calculated from the local distances between a deviated feature and a reference feature (see ISO 22432) is a situation characteristic (see ISO 17450-1), which is used for geometrical specification (s
