Pencil hardness tester
This is a simple and effective technique to evaluate the hardness of many coatings.
The pencil lead, prepared beforehand by rubbing it on fine abrasive paper, is maintained at an angle and pushed with uniform pressure onto the sample, leaving either a superficial trace or causing destruction down to the substrate.
The Pencil Hardness Tests are supplied complete with stand and a series of 14 pencils, ranging from 6B to 6H hardness values.
Pencils of various grades of hardness are moved over the coated area at a specific angle and pressure. The hardness of the pencil which damages the surface determinates the hardness of the coating. The repeatability is assured by the pencil holder.
- Assortment of 14 graded pencils, ranging in hardness from: 6B, 5B, 4B, 3B, 2B, B, F, HB, H, 2H, 3H, 4H, 5H. 6H.
