Eqn. 1
\require{color}\definecolor{myred}{RGB}{255,0,0} R_{\color{myred}a}\approx\frac{R_{\color{myred}a\;max}+R_{\color{myred}a\;min}}2=\frac{0,03\cdot R_{\color{myred}z}^{\color{myred}1,3}+0,24\cdot R_{\color{myred}z}^{\color{myred}1,06}}2

Calc 1
Average roughness value Ra from averaged roughness depth Rz.

The average roughness depth Rz has now been deleted as an ISO characteristic value.
