There are different methods of determining how hard a certain coating is. These methods are pencil scale and the Mohs scale, both using the symbol “H” with numbers to assign hardness scale. Most consumers get confused as manufacturers often fail to point out the difference between these methods, which leads to inappropriate claims of the hardness of certain coatings. While Pencil Hardness used for ceramics coatings, paint coatings in accordance with standard ASTM D3363, the Mohs scale is mostly for mineral stones such as diamond, quartz, etc. A mineral scale 9 take one of the hardness material diamond) can have a Mohs scale of 6H and a pencil scale of 8H.

 A pencil hardness test is carried out in such a way that progressively the higher grades of hardness are used to firmly press or move on the to be tested coating. (There is a debate as to whether the pencil has to move or just pressed at 45 degrees). It is until the hardness grade pencil does not leave a mark on the surface of the coating that the coating is assigned the hardness of the used grade of pencil. The actual performance of the coating rellies on its hardness. Higher scaled coatings will wear and tear better than lower scaled coatings.

BEVS 1301 Pencil hardness Tester is used to determine the resistance of coating material or scratch hardness. The BEVS1301/ 1000g Pencil Hardness Tester complies with the requirements of ASTM D3363 and ISO15184 standard, through leaving a superficial trace on the dry coating film with a certain pencil hardness, the surface will be variably damaged by the hardest pencil to evaluate pass/fail or hardness. Recommend to apply on the smooth film surface. Use a variety of different hardness pencils, the angle between pencil and the coated surface is 45°, scratch on the coated surface under a certain of force, the scratch resistance hardness of the coating is the pencil hardness which just scratched the coating. Pencils are moved with a fixed pressure of 1000 grams. The angle between the pencil and the film surface is 45 degrees.

Surface hardness testing and adhesion testing are important testing methods in the coatings industry. These test methods are regulated by industry standards- ASTM D 3359 for adhesion by tape and ASTM 3363 for film hardness by pencil test or pencil hardness test. Paints do not only need to adhere to surfaces onto which they are applied, but also must be sufficiently hard to withstand friction, wear and protect the surface. In the paint industry, it is common to have manufacturers list the hardness of paints in pencil hardness, an inexpensive but quick method to measure hardness organic coatings. To test the hardness, pencils are available of different graphite hardness – 6B is usually the softest pencil grade of the pencil and up-to 9H. Wolff-Wilborn Pencil Hardness Test according to Standards ASTM D3363, BS 3900-E19, ECCA ECCA T, ISO 15184 has the graphite coatings (grading scale) hardness includes 20 pencils.

Pencils are moved with a fixed pressure of 1000 grams. Use the paint pencil hardness scale. The angle between the pencil and the film surface is 45 degrees with the constant exerted force of 1000g. This pencil Hardness has 14 Mitsubishi pencils -6B- 5B -4B -3B -2B -B -Hb -F -H- 2H- 3H- 4H- 5H-6H .
