Pencil Hardness Tester
A Pencil Hardness Tester is a coating and surface-testing instrument used to determine the scratch hardness and resistance of paint, varnish, lacquer, plastic, and other coated surfaces. It evaluates the hardness of a coating by moving pencils of different hardness grades across the surface under controlled pressure and angle.
Key Features
Suitable for paint & coating hardness testing
Uses standard pencil hardness grades from 6B to 6H
Controlled testing angle and load
Robust and easy-to-use construction
Helps determine scratch resistance and coating durability
Suitable for laboratory and quality-control applications
Commonly used for automotive, metal, plastic, furniture, appliance and industrial coatings
Typical Test Principle
A pencil of known hardness is positioned at a specified angle against the coated surface and moved across it with a controlled load. The coating is inspected for scratching, gouging or deformation. The hardness grade is reported according to the highest pencil hardness that does not damage the coating.
Common Standards
ASTM D3363 – Film Hardness by Pencil Test
ISO 15184 – Paints and varnishes — Determination of film hardness by pencil test
JIS K 5600-5-4 – Pencil hardness testing
