Roughness measurement is being done in line with EN ISO 16610-21:2013-02 and EN ISO 4287:1999. It is being done using contact devices and in the workshop by using the comparison method with gauge blocks.

The contact method determines parameters Ra, Rz, Rt, Rm, Rp, Sm, S, tp for 14 of the roughness class. Production of results is made by using Gauss’ filtration method, with simultaneous possibility of report preparation.
