The work of preparing Internati

18、onal 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 with IS

19、O, 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 technical co

20、mmittees 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 to the

It influences the chain link 5 of the chain of standards on roughness profile,

26、waviness profile, primary profile and areal surface texture. This part of ISO 25178 describes a classification system for methods used primarily for the measurement of surface texture. The classification system provides a context for the development of other parts of ISO 25178 that describe characte

27、ristics and measurement standards for some of the individual methods. Such a classification is also intended to aid in choosing and understanding various types of methods and in determining which standards apply to their application. The classification system is aimed to be as general as possible. H

32、y Basic and general concepts and associated terms (VIM) 3 Terms and definitions 3.1 General terms For the purposes of this document, the terms and definitions given in ISO 4287, ISO 25178-2, ISO/IEC Guide 99 and the following apply. 3.1.1 measurement coordinate system system of coordinates in which

33、surface texture parameters are measured NOTE 1 If the nominal surface is a plane (or portion of a plane), it is usual to use a rectangular coordinate system in which the axes form a right-handed Cartesian set, the X-axis being the direction of tracing co-linear with the mean line and the Y-axis also

34、 lying on the nominal surface, and the Z-axis being in an outward direction (from the material to the surrounding medium). The rectangular coordinate system is adopted in this part of ISO 25178 except for 3.2.1, Note 3, and 3.3.3, where a cylindrical coordinate system is described. NOTE 2 See also s

35、pecification coordinate system ISO 25178-2:. 1) To be published. BS EN ISO 25178-6:2010ISO 25178-6:2010(E) 2 ISO 2010 All rights reserved3.1.2 surface profile profile that results from the intersection of the real surface by a specified plane NOTE In practice, it is usual to choose a plane with a no

36、rmal that nominally lies parallel to the real surface and in a suitable direction. ISO 4287:1997, definition 3.1.4 3.1.3 ordinate value z(x, y) height of the surface at position (x, y) 3.2 Definitions for classification of surface texture measurement methods 3.2.1 line-profiling method surface topog

37、raphy measurement method that produces a two-dimensional graph or profile of the surface irregularities as measurement data, which may be represented mathematically as a height function z(x) NOTE 1 By contrast, areal-topography (3.2.2) and area-integrating (3.2.3) methods are used to quantify the su

38、rface texture over a selected area of a surface instead of over single profiles. NOTE 2 Examples of instruments that were developed specifically to measure line profiles include contact stylus scanning1, early versions of the phase-shifting interferometer3, and the optical differential profiler45. N

39、OTE 3 Certain methods have rotational scanning within a cylindrical coordinate system and measure circular profiles, that is, z as a function of angle . One example is the circular interferometric profiler6. 3.2.2 areal-topography method surface measurement method that produces a topographical image

40、 of a surface, which may be represented mathematically as a height function z(x, y) of two independent variables (x, y) NOTE 1 Examples of methods that have been developed or adapted for areal-topography measurements include contact stylus scanning7, phase-shifting interferometric microscopy8, coher

41、ence scanning interferometry910, confocal microscopy11, confocal chromatic microscopy12, structured light projection1314(including triangulation), focus variation microscopy15, optical differential profiler45, digital holography microscopy16, point autofocus profiling1718, angle-resolved scanning el

42、ectron microscopy (SEM)1920, SEM stereoscopy2122, scanning tunnelling microscopy23, and atomic force microscopy2425. The areal measurement capability of these methods is often derived from a set of parallel profiles scanned sequentially or from manipulation of 2D images in microscope cameras. All of

43、 these methods may also be used to produce line-profiling results as well. NOTE 2 For methods that form a surface topography image z(x, y) from sequential profiles such as a set of parallel profiles z(x), care should be taken to ascertain the accuracy of measurement along the slow axis z(y). Althoug

44、h z(x, y) topographic images may be displayed for an areal texture method, in some cases the method may not actually be sensitive to z(y) topography changes, or the accuracy of z(y) profiling may be limited by the drift of the instrument. 3.2.3 area-integrating method surface measurement method that

45、 measures a representative area of a surface and produces numerical results that depend on area-integrated properties of the surface texture NOTE 1 These methods do not produce line-profile data z(x) or areal-topography data z(x, y). NOTE 2 Examples of instruments that have been developed as area-in

46、tegrating methods include those that use the techniques of total integrated light scatter26, angle-resolved light scatter27, parallel-plate capacitance28and pneumatic (flow) measurement29. NOTE 3 Area-integrating methods have been used in conjunction with calibrated roughness comparison specimens or

47、 calibrated pilot specimens as comparators to distinguish the surface texture of parts manufactured by similar processes or to perform repetitive surface texture assessments.

48、 contact stylus scanning surface topography measurement method whereby the probing system uses a contacting stylus whose motion is converted into a signal as a function of position NOTE See ISO 25178-601 for more information. 3.3.2 phase-shifting interferometric microscopy PSI surface topography mea

49、surement method whereby an optical microscope with illumination of a known effective wavelength is integrated with an interferometric attachment and produces multiple successive optical images with interferometric fringes from which the profile or areal surface topography image is calculated NOTE 1 Bands of light and dark interferometric fringes are produced in images when two or more mutually coherent optical beams are combined. NOTE 2 See ISO 2
