Sutherland Rub Test  

The tester is a motor driven instrument for moving a weighted test strip over a printed specimen through an arc. This test instrument is used in various ways to expose paper surfaces to a rubbing action and test its resistance to damage. The test is generally run according to TAPPI Test Method T830. Some tests are run dry, while others are run wet or with moistening of the surfaces. Some tests are run with the test material rubbed against itself, while others rub the surface with some other material.
