Overview of PENCIL SCRATCH HARDNESS TESTER (MANUAL)
This tester is used to evaluate the hardness of coated film according to the testing machine method.
Scratching the paint surface with a pencil attached at a 45° angle, the operator is to determine the hardest pencil that does not tear or damage the coated film.
The tester can also be used to evaluate the hardness of decorative sheet and resistance to solvents on enameled wire.
By attaching optional jigs, tests compliant with JIS K7317 (scratch hardness test for specialty films) can also be performed.
