In which of Guo Jingming's books did you read it?

rz refers to the height of the microscopic unevenness at ten points. In the old version of the national standard GB T3505-1983, it is stipulated that the evaluation parameters of surface roughness should be selected from three aspects: the arithmetic mean deviation of the contour (RA), the height of the ten points of the microscopic unevenness (RZ) and the maximum height of the contour (RY).

Microscopic unevenness ten-point height rz: the sum of the average of the five largest profile peak heights and the average of the five largest profile valley depths within the sampling length l.

Commonly used sampling lengths are:rz, l=;

rz, l=;

rz, l=;

rz, l=;

At RZ>50-320 m, l=8mm.

The definition of RZ has been changed in the new version of the national standard GB T3505-2000 (2009 latest), the marking method Ry in the old standard is no longer used, and the definition of RZ representing the height of ten points of microscopic unevenness has been cancelled. In the new version, RZ replaces RRY and is defined as the maximum height of the profile.
