This book was written for the practitioner with the aim of presenting characteristics and
methods of roughness measurement in an easily understandable form. Definitions of the surface
parameters can be found in the relevant standards. Older parameters are also explained to the
extent that they still have a worthwhile meaning today. In practice it is quite common to
leave the entries in the drawings unchanged over the entire life cycle of a product. This is
based on the valid ISO standards. This guide Surface texture - Theory and practical use is
intended to explain the different roughness parameters and make it easier for the designer to
specify surface parameters.
