The JIS K5600-5-4-1999 standard specifies a test method for marking Hardness (pencil method) in the Mechanical Properties of paint films. This method evaluates the Hardness of paint films by marking on the paint film with pencils of different Hardness grades. The top layer film suitable for single-layer or multi-layer coating systems is mainly used to compare the Hardness of different coatings and is suitable for flat surfaces. The test results provide important data for quality control and performance evaluation of paint products.
