Scratch Hardness Tester TriForcePencil, Model 293

Pencils of various grades of hardness are moved over the painted surface at an angle of 45° to the horizontal with a force of 5 N, 7.5 N or 10 N (± 0.1 N). The pencil hardness is defined by those two grades of hardness the softer one of which just produces a writing trace while the next harder one leaves a perceptible scratch on the coating.

Scratch Hardness Tester TriForcePencil 293
(REFERENCE CLASS)

A simple standardized method for testing surface hardness

The pencil method belongs to the group of scratch hardness testing instruments. This is a
simple and quick method for testing the surface hardness of coatings with regard to stresses
inflicted by scratching with sharp edges, or other rough surfaces.
It can also be applied during production, e. g. for coil coatings.

The equipment of the TriForcePencil 293 with three test loads ( 5 N / 7,5 N / 10 N ) instead of
usually only one ( 7,5 N ) meets the increasingly possibility of variation of the test load for this
type of testing even currently demanded in the Asian market
