Description / Abstract:

Scope and purpose

This standard defines concepts used for describing the metrological properties of electrical contact (stylus) instruments for the measurement of surface roughness for which the manufacturer is required to state tolerances .

The intention is to describe principles of the hardware for measuring roughness quantities (e.g. Ra, Rz, Rmax as given in DIN 4768 Part 1 and Pt as given in DIN 4771) and to facilitate understanding between manufacturers and users of these instruments.
