The NF T30-126-2020 standard specifies a method for determining the Hardness of coatings and varnish coatings using a pencil test. For top coatings of single-layer or multi-layer coating systems, the Hardness of coatings is assessed by swiping pencils of different Hardness grades on the surface of the coating. This method provides a fast and easy means of testing coating Hardness comparison and quality control, especially for smooth surfaces.
