Coefficients of static and kinetic friction of uncoated writing and printing paper by use of the horizontal plane method, Test Method TAPPI/ANSI T 549 om-20 

 

This method describes a horizontal plane procedure for the determination of the coefficient of static and kinetic friction of paper measured when sliding against itself.

The horizontal instrument requires some means of movement of the specimen in relation to the surface upon which it rests. The coefficient of friction (COF) is measured directly from the resistance to tangential motion and the applied weight pressing two pieces of paper together.

Static COF relates to the force required to initiate movement between two surfaces while kinetic COF relates to the force required to cause continuation of the movement at uniform speed.

The determinations of COF for packaging materials is described in TAPPI T 815 “Coefficient of Static Friction (Slide Angle) of Packaging and Packaging Materials (Including Shipping Sack Papers, Corrugated and Solid Fiberboard) (Inclined Plane Method).” In the method for testing packaging materials, the force measurement is often made on the third slip, while in this method the determination is made on the first slip.
