Introduction This part of IS0 13565 is a Geometrical Product Specification (GPS) standard and is to be regarded as a General GfS standard (see ISO/TR 14638). It influences chain links 2 and 3 of the
21、chain of standards for roughness profile. For more detailed information of the relation of this standard to other standards and the GPS matrix model, see annex A. The roughness profile generated using the filter defined in IS0 11 562 suffers some undesirable distortions, when the measured surface co
22、nsists of relatively deep valleys beneath a more finely finished plateau with minimal waviness. This type of surface is very common, for example in cylinder liners for internal combustion engines. This part of IS0 13565 provides a method of greatly reducing these distortions, thus enabling the param
23、eters defined in IS0 13565-2 and IS0 13565-3 to be used for evaluating the above mentioned type of surface, with minimal influence from these distortions. Page 3 EN IS0 13565-1 : 1997 1 Scope This part of IS0 13565 describes a filtering method for use with surfaces that have deep valleys below a mor
24、e finely finished plateau with a relatively small amount of waviness. The reference line resulting from filtering according to IS0 11562 for such surfaces is undesirably influenced by the presence of the valleys. The filtering approach described in this standard suppresses the valley influence on th
25、e reference line such that a more satisfactory reference line is generated. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 13565.

29、2,5 To measure profiles in accordance with this part of IS0 13565, a measuring system which incorporates an external reference is recommended. In case of arbitration the use of such a system is obligatory. 5 Traversing direction The traversing direction shall be perpendicular to the direction of lay
30、 unless otherwise indicated. 6 Filtering process to determine the roughness profile The filtering process is carried out in several stages giving the modified profiles, sections of which are illustrated in figure la) to d). The first mean line is determined by a preliminary filtering of the primary
31、profile with the phase correct filter in accordance with IS0 11562 using a cut-off wavelength Ac in accordance with clause 7 and corresponding measuring conditions in accordance with table 1 of IS0 3274:1996. All valley portions which lie below this mean line (shown hatched in figure la) are removed
32、. In these places the primary profile is replaced by the curve of the mean line. The same filter is used again on this profile with the valleys suppressed. The second mean line thus obtained (see figure 1 b) is the reference line relative to which the assessment of profile parameters is performed. T
33、his reference line is tranferred to the original primary profile (see figure IC) and the roughness profile according to this part of IS0 13565 is obtained from the difference between the primary profile and the reference line (see figure Id). 7 Selection of the cut-off wavelength Ac and the evaluati
34、on length In The measurements shall preferably be carried out using a cut-off wavelength of Ac = 0,8 mm. In justified exceptional cases, Ac = 2,5 mm may be selected and this shall be stated in the specification and test results. Table 1 provides the relationship between cut-off wavelength Ac and the
