Pencil hardness test to evaluate the hardness of the coating film. It is a high-performance, cost-effective model.
It is used to measure the hardness of coatings. It is designed to apply a load of 750g ± 10g at the tip of the pencil. The angle of the pencil is fixed at 45° ± 1°, and the top of the testing device is equipped with a level. By using this equipment, reproducible tests can be conducted, allowing for the same evaluation regardless of who performs the test. The main body is made of steel and is powder-coated, with a product specification that ensures the load accuracy is within the range of 750g ± 5g. It is a high-precision model with high cost performance. It is also effective for applications beyond painting. It is used for evaluating the hardness of hard coatings on films, surface hardness of liquid crystal displays (LCDs), and hardness evaluation of resin products, establishing itself as a standard for hardness evaluation. The lineup includes three types with loads of 750g, 1000g, and 500g, each corresponding to JIS-K5600-5-4, JIS-K5400, and industry-specific standards (500g).

basic information
Sharpen the pencil only on the wooden part, exposing the core by 5 to 6 mm. Set the pencil in the testing device, applying a load of 750g ± 10g on the tip of the pencil core while maintaining an angle of 45° ± 1°. Push at a speed of 0.5 to 1 mm/s for a distance of at least 7 mm. Wipe the pencil core powder from the coating surface with a soft cloth or cotton wool and an inert solvent, and check for scratches or indentations. The hardness of the coating is determined by the soft pencil just before the one that left a scratch (the hardest pencil that did not leave a scratch).
