WebFriction tester is a kind of testing equipment which is used to measure coefficient of friction (COF) for materials. Basically, there are two kinds of coefficients: static coefficient of friction and kinetic coefficient of friction. WebStatic coefficient of friction of polish-coated flooring surface is measured by the James machine. 7 The method measures coefficient of friction between test surface (e.g., shoe soles or heel materials) and walkway surface. Floor surfaces, which have static coefficient of friction of less than 0.5, are non-hazardous. ghandi clothes name

What are the Uses of the Coefficient Of Friction Tester?
