Hardness of paint film by pencil

The pencil hardness test for paint films involves drawing a standard pencil across the coating surface at a fixed angle and pressure to determine the hardness grade based on whether scratches are produced. It is used to evaluate the scratch resistance of surfaces such as coatings and plastics, with results corresponding to international standard hardness ratings.
Selection
Select the corresponding pencil grade based on the hardness range of the material being tested, with higher grades chosen for harder materials. Ensure the pencils comply with the ASTM D3363 standard and sharpen the lead flat with sandpaper before testing. The ambient temperature and humidity must meet the standard requirements, and each grade of pencil should be tested three times to obtain stable results.
