The work of preparing I

19、nternational Standards is normally carried out through ISO technical committees. 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

20、 with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of techni

21、cal committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn t

36、.1 GeneralThe complete specification operator (see ISO 17450-2) consists of all the operations required for an unambiguous specification. It consists of a full set of unambiguous specification operations in an unambiguous order. For areal surface texture, the complete specification operator defines

37、the type of surface, method of extraction, association method and filtration for surface texture by areal methods.If form error is to be included in the measurand, then a S-F surface shall be specified; otherwise, an S-L surface shall be specified.4.2 Method of extraction4.2.1 Evaluation area4.2.1.1

38、 GeneralThe evaluation area consists of a rectangular portion of the surface over which an extraction is made.The orientation of the evaluation area shall be controlled by the specification.NOTE 1 If the nesting index is the same in orthogonal directions, then the orientation does not matter.NOTE 2

39、The orientation of the evaluation area is typically influenced by the form; this means that the sides of the rectangular area are parallel/orthogonal to the nominal geometry (e.g. cylinder axis, sides of a rectangular flat, etc.).4.2.1.2 S-F surfaceFor an S-F surface, if not otherwise specified, the

40、 evaluation area shall be a square. If the F-operation is a filtration operation, then the length of the sides of the square evaluation area is the same length as the filter “nesting index”. If the F-operation is an association operation, then the length of the side of the square evaluation area is

41、used as a substitute for the F-operation nesting index value. This chosen value for the F-operation nesting index is used for all subsequent operations.The value of the nesting index for the F-operation is normally chosen from the following series:.; 0,1 mm; 0,2 mm; 0,25 mm; 0,5 mm; 0,8 mm; 1,0 mm;

42、2,0 mm; 2,5 mm; 5,0 mm; 8,0 mm; 10 mm; .NOTE 1 An example of an F-operation with a nesting index is a spline filter. The total least squares fit of the nominal form is an example of an F-operation without a predefined nesting index.NOTE 2 The value of the F-operation nesting index is typically chose

43、n to be five times the scale of the coarsest structure of interest.4.2.1.3 S-L surfaceFor an S-L surface, if not otherwise specified, the evaluation area shall be a square whose sides are the same length as the L-filter nesting index value.The value of the nesting index for the L-filter is normally

44、chosen from the following series:, 0,1 mm; 0,2 mm; 0,25 mm; 0,5 mm; 0,8 mm; 1,0 mm; 2,0 mm;2,5 mm; 5,0 mm; 8,0 mm; 10 mm; .NOTE The value of the L-filter nesting index is typically five times the scale of the coarsest structure of interest.2 ISO 2012 All rights reservedBS EN ISO 25178-3:2012ISO 2517
