Surface Friction Fixture

The Schap Surface Friction Fixture is applicable to all types of leather and may be used with other materials and drag sledges. The fixture is used for determining the coefficient of friction of the surface of leather, per specification IUP 51. A leather sample is attached to a smooth surface of the sledge. This is placed on the level surface of a specified reference material. The static coefficient of friction between the two surfaces is determined from a measurement of the force required to initiate movement of the mass. The dynamic coefficient of friction is determined from the average force required to maintain movement.

Other variants of this test device can be made to meet other test specifications, contact us for more information

The Friction Sled may be used with the Schap Universal Test Machines.
