It influences the chain link 6 of the chains of
32、standards on areal surface texture, roughness profile, waviness profile and primary profile.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. The default de
33、cision rules given in ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise stated.For more detailed information of the relation of this standard to the GPS matrix model, see Annex E.This part of ISO 25178 introduces material measures that can be used for period

42、eral A material measure can be used for two different purposes: calibration of the metrological characteristics, followed by assessment of the measurement uncertainty; user adjustment of the instrument, which establishes corrections of the measured quantities.Both purposes depend on the metrological
43、 characteristics of the material measures (see the ISO 25178-700 series).The material measures presented in this part of ISO 25178 are suitable for both purposes; nevertheless, they have been especially designed for the assessment and correction of systematic errors. This is due to the fact that the
44、 characteristics of those material measures permit the calibration of coordinates such as x, y and z through the assessment and verification of adjustment coefficients Cx, Cyand Cz(see the ISO 25178-600 series).These material measures are not intended to separate the errors introduced by the instrum
45、ent from those due to the filtering and computation algorithms. The algorithms can be tested using software measurement standards (see ISO 5436-2, ISO 25178-71 and ISO 25178-72).Most of the material measures presented below permit the verification and the correction of the squareness between X and Y
46、 drive units on areal instruments.The measurement method and the characteristics of the material measure shall be supplied by the manufacturer of the material measure.In ISO 25178-2, each term is followed by its parameter (abbreviated term), then its symbol. Whereas abbreviated terms can contain mul
47、tiple letters, symbols consist only of a single letter with subscripts as needed. For these terms, symbols are used in the equations shown in this document. The reason for this differentiation is to avoid misinterpretation of compound letters as an indication of multiplication between quantities in
48、equations. The parameters (abbreviated terms) are used everywhere else in this document as well as in product documentation, drawings and data sheets.5 Requirements for the material measuresThe design characteristics of material measures shall be compatible with the considered application. See also
49、Annex A.The material characteristics of the material measure shall not significantly affect the measurement carried out on it.The real integral surface of a standard shall have a scale limitation specified and features outside this limitation shall be considered not to affect the measurement.Examples of such features are: flatness deviation of the real integral surface of the standard; form deviation of the groove(s) (i.e. for PGR, PGC, PDG, AGP, AGC, etc.); groove bottom radius (i.e. for PGC, PCS, PDG,
