    10.5.5 Maximum two point height of the profile, Ry (DIN, ANSI) 10.5.6 Maximum height of the profile, Rz (DIN, ISO, ANSI) Obtain the sum Zi of profile peak height Pi and profile valley depth Vi within each sampling length. The maximum value of all Zi’s over the evaluation length is defined as Ry (DIN, ANSI), and the mean value is Rz (DIN, ISO, ANSI).
  • Page 181: Mean Width Of The Profile Elements, Sm (Jis, Iso, Din)

    10. REFERENCE INFORMATION 10.5.9 Mean width of the profile elements, Sm (JIS, ISO, DIN) A portion projecting upward over the given upper count level is called a peak, and a portion projecting downward below the given lower count level is called a valley. The mean of the profile element (profile peak and the adjacent profile valley) widths within a sampling length is defined as Sm.
  • Page 182: Material Ratio Of The Profile, Mr

    10.5.11 Material ratio of the profile, mr Ratio (%) of the material length of the profile elements at a given level (slice level) to the evaluation length. Here the slice level is defined as the depth from the highest peak, and is called a “peak reference”.
  • Page 183: Mean Spacing Of Local Peaks Of The Profile, S

    10.5.13 Mean spacing of local peaks of the profile, S S is the mean spacing of adjacent local peaks. For ANSI, this S is defined over the evaluation length. ∑ ● Local peaks If an upward convex portion of an assessed profile has concavities on both sides, the highest point of the convexity is called a local peak.
