Purpose: Determine the hardness of the paint film by the pencil hardness level of the paint film. Technical characteristics: The hardness is the pencil hardness level table of the paint film broken by the plow under the specified test conditions.
Compliance with standards: Designed according to GB/T 6736-2006, ASTM D 3363 and conforming to various national standards. The weight of the pen tip (500g/750g/1000g) can be changed through the loading block, which is simple and convenient.
technical parameter:
*The pressure of the pencil lead to the coating film: 1000g/750g/500g (two loading blocks correspond to 750g and 1000g respectively)
* The angle between the pencil and the measured surface: 45o
* Three-point contact with the measured surface (roller, pencil lead)
* Standard configuration: one pencil hardness tester; one spacer, one eraser*, one set of pencils (13 pieces of B-6H), one piece of sandpaper 400#
