— A definition of bristle stiffness and a measuring method are described and discussed. Sixty‐six different brush models, collected worldwide, were measured according to the suggested method. Considerable differences were found between brushes of declared equal stiffness. On the basis of these findings and the method described, a classification is suggested.
