PENCIL HARDNESS TESTER

The Pencil Hardness tester is the most common but

also the most inconsistent technique to measure the

hardness of a coating. This test conduct scratch

hardness tests to determine the resistance of

coating material in order to prevent the scratches

on the surface.

In the test, pencils of various degrees of hardness

are moved over the surface under a fixed pressure

and angle to the surface. The degree of hardness of

the pencil which damages the surface is taken s a

measurement of scratch hardness e.g. 3H hardness.
