8.3 Parameters Definitions
8.3.1 Arithmetical Mean Deviation of Profile Ra

Ra is arithmetic mean of the absolute values of profile deviation Z(x) from mean within sampling length.

8.3.2 Root-mean-square Deviation of Profile Rq

Rq is the square root of the arithmetic mean of the squares of profile deviation Z(x) from mean within

sampling length.

8.3.3 Maximum Height of Profile Rz

Rz is the sum of height Zp of the highest profile peak from the mean line and depth Zv of the deepest

profile valley from the mean line within sampling length.

8.3.4 Total Peak-to-valley Height Rt

Zv and Rt is the sum of the height of the highest peak Zp and the depth of the deepest valley Zv over the

evaluation length.

8.3.5 Maximum height of Profile Peak Rp

Rp is the height from the highest profile peak line to mean line within sampling length.
