ISO standard pencil hardness Tester

The ISO standard pencil hardness tester determines the hardness of a coating by scratching its surface with pencil leads of varying hardness at a fixed angle and pressure, and assessing whether scratches are produced. It is used for quality control in industries such as coatings and plastics, and complies with the ISO 15184 standard.
Selection
When selecting, consider the type of test material and the estimated hardness range to match the corresponding pencil model. Ensure the instrument complies with ISO standards and check the scratch angle and load accuracy. Choose between manual or electric models based on routine testing needs, paying attention to the stability of the pencil holder and the flatness of the testing platform.
