Description
The Koh-I-Noor 1500 Pencil Set is a premium collection of 20 pencils ranging from 8B to 10H, designed for precise scratch hardness testing of coatings and paints using the Wolff Wilborn method. Housed in a sturdy aluminum case, each pencil ensures consistent performance and durability, minimizing operator error during testing. The set is fully compliant with international standards such as ISO 15184, ASTM D3363, JIS K-5600, and ECCA-T4-1, making it suitable for use in laboratories, quality control, and product development across industries including automotive, furniture, and industrial coatings.
Engineered for reliability, the pencils are used in conjunction with a standardized pencil holder that applies a fixed load—either 750 g or 1000 g—across the test surface at a consistent 45° angle. This allows accurate determination of a coating’s resistance to scratching, gouging, and surface damage. The comprehensive range of hardness grades enables precise identification of material durability, while the ISO 15184 certification ensures the set meets internationally recognized testing protocols, making it an essential tool for professionals assessing the mechanical properties of surface finishes.
