Description

TQC Pencil Hardness Test according Wolff Wilborn provides in a simple method to test the scratch hardness of coatings. We use pencils in a range of 6B to 8H hardness-grade for this test. With constantly pressure on pencil will moved scratching over the surface under a 45° angle. Afterward an optical assessment is carried out to see which pencil hardness damages the surface. Delivered with a set of 20 Koh-i-noor pencils and also a pencil sharpener.

The models differ in load on the pencil tip (in grams). This differs per standard. See also ‘Order Information’.

The purpose of scratch hardness tests is to determine the resistance of coating materials or lacquers to scratch effects on the surface. This test is of particular value for furniture or vehicle lacquers, but is also a useful aid in the development of synthetic resins or other film forming materials.

Scratch hardness generally measured by moving a sharp object under a known pressure over the test surface. The result may either be the value of the pressure required to scratch through the test material if a scratching tool of constant hardness is used, or the hardness of the scratching tool is varied while constant 750 g pressure is applied.

  • Twenty pencils from grade 9B to 9H are use with a standard holder.
  • Pencils are move over the surface under a fix pressure and also a fix angle to ensuring the least amount of operator error
  • Pencils can be easily exchang to minimize down time during the test.
