ASTM D3363-00 Pencil Scratch Method Film Hardness Pencil Coating Hardness Tester

ASTM D3363-00 Pencil Scratch Method Film Hardness Pencil Coating Hardness Tester

Product details

Coating hardness is the necessary measurement for the performance of coatings. This instrument applied the Pencil Scratch Method. It is a fast and economical way to determine the film hardness using the drawing lead core or the pencil core. The pencil scratch method for coating hardness testing is a common method in the world since the 1980s. In China, this test method has also been promoted to the coating research and industrial production. The instrument can be used both in laboratory and on site.

Referenced standard, Coating Hardness Pencil Test Method Standard Test Method for Determination of Coating Hardness by Pencil Test Method General Method for Preparing The Film 2.

Specification and principles

Load Weight 1000g /750g /500g Measurement Angle (Between Pencil and Measured Surface), 45° Three Touch Points (Two Wheels, a Pencil Core). Scratch Speed: about 1mm/s.

Usage

The instrument applies mechanical measurement. Keep three point touch the coating (two wheel, a pencil core), and a 45 degree angle between pencil and test surface. Push the instrument sliding, pencil draws the corresponding track in the coating. In the change of different pencil marks, the hardness value of the film can be determined.

NOTE

* When sharpening pencils, pay attention that the core should be cut out the shape of a cylinder.

* When inserting a pencil into the tester, it is necessary to use a horizontal pad block, so as to avoid the angle deviation.

* When pushing forward the tester, don't push too hard, ensure the force is enough to keep the tester moving forward, so as to avoid breaking the pencil.

* After drawing one line, it is necessary to release the fastening screws and rotate the pencil to draw another line.

* To choose pencil in test procedure: In accordance with the order of 6H-5H4H-3H-2H-H-HB-B-2B-3B-4B-5B6B, from hardest to softest.

* Check the appearance and property of sample before using the instrument. Ensure that the test sample is with regular property, no damage, no cracks, no scratches, etc. And the surface is smooth. * It is recommended to wear gloves to use this instrument to prevent rusting.
