ISO friction coefficient tester

The friction coefficient of paper is one of important indices that express the paper surface condition, related to touch and ease of work of paper. This tester is based on the measurement method of friction coefficient newly specified by ISO. The friction of paper sheets applied to the moving table and weight is measured three times, to determine both static and dynamic friction coefficients. An initial torque is applied very slowly so that it takes 0.5 to 5 seconds to reach the peak of static friction. Unlike the conventional rapid measurement of static friction, this method measures friction between fibers in paper surfaces.
