Instruments for the measurement of surface roughness by the profile method. Contact (stylus) instruments of progressive profile transformation. Profile recording instruments
This International Standard relates to contact profile recording instruments used for the measurement of surface roughness. It specrfies
— the basic terms, definitions and symbols relating to profile recording instruments;
— the main parameters of these instruments and their numerical values;
— the standards of accuracy for profile recording instruments (admissible values for errors of vertical and ' horizontal magnifications, deviations of the tip radius of the
stylus and stylus angle).
Calibration methods are given in the annex.
