Description

The instrument is designed to determine the hardness of coatings by pencil leads in compliance with: ASTM D 3363, ECCA T4, EN 13523-4, ISO 15184:2012, JIS K 5600-5-4.

Application

The instrument is widely used for hardness testing of powder and liquid paint coatings. For high accuracy of the results, the lead of pencil should be sharpen under 90 ° angle. The tests begin with the softest pencil leads. If after applying there is no any signs of damage on the tested coating, user will have to repeat the test with one grade harder pencil leads. The MAX hardness value of pencil leads, that leaves no any traces of destruction on the coating, is hardness value of tested coating (for example: 3H, 2H, H, HB, B, 2B, etc.).
