Product Description
Pencil Hardness Tester A Pencil Hardness Tester is a device used to determine the scratch resistance and hardness of materials, particularly coatings, paints, and surfaces. Here's an overview: How it works: 1. A standardized pencil (typically 6H to 6B) is mounted in the tester. 2. The pencil is pressed onto the surface with a controlled force (usually 500g or 1kg). 3. The pencil is moved across the surface at a 45 angle. 4. The hardness is determined by the pencil's ability to scratch or mark the surface. 5.Manual: Simple, handheld devices. Standards and Applications: 1. ASTM D3363 (Standard Test Method for Film Hardness by Pencil Test) 2. ISO 15184 (Paints and varnishes Determination of film hardness by pencil test) Benefits: 1. Quick and easy testing 2. Low-cost equipment 3. Non-destructive testing The pencil hardness scale ranges from: - 6H (very hard) to 6B (very soft) - Higher hardness values indicate greater resistance to scratching. The Pencil Hardness Tester provides a simple, cost-effective way to evaluate surface hardness and scratch resistance, helping ensure product quality and durability.
