Test instructions: Use a hardness pencil to scratch the surface of the coating to test the surface hardness of the coating layer. The hardness pencil is used to45Fixed at a certain angle, with the front pen center in contact with the surface of the coating layer, and appropriately loaded at a certain speed（JISstandard0.5mm/Move the test platform in seconds to move the surface of the coating layer past the center of the pen, and the coating layer will not cause damage (scratches). The hardness of the coating layer can be considered as the level of the soft pencil.

Pencil scratch testerUsage:

1Preparation: Use a pencil sharpener (art knife) to pin the pencil until the lead is exposed5-6mm(Never loosen or cut the pen core) Hold the pen core and make it compatible with“NO:400”Sandpaper surface90Make an angle of ° and continuously make circles on sandpaper to rub the end face of the pen lead until a flat and sharp edge of the lead core is obtained (the edge must not be broken or chipped). The pencil should be rotated after each use180Reuse or regrind before use.

2Operation: Place the instrument on a flat workbench, place the product to be tested on the workbench and fix it. Insert the sharpened pencil into the main hole of the instrument, and the edge of the pencil contacts the workbench. Then tighten the screw and add the required test weight (weight).

3After powering on, place the instrument at a rate of approximately per second1-5mmPush forward at a speed according to the standard. Starting from the hardest pencil, plow five times per level of pencil3mmLong marks, until the pencil that does not damage the coating is found, the hardness of this pencil represents the pencil hardness of the coating being measured.
