Abstract

An apparatus for measuring the grip of a subject surface, comprising a weighted member, means for applying a force to move the weighted member with respect to the subject surface, and means for measuring the force applied to move the weighted member, the apparatus further comprising a surface assembly having a test surface for contacting the subject surface and onto which the weight of the weighted member is applied, wherein the surface assembly comprises means to allow the test surface to be interchanged.
