Surface Scratch Resistance Tester is used to conduct scratch tests on solid insulating accessible parts or printed circuit boards in household appliances, information technology equipment, and similar products. By applying standardized scratches to the specimen surface under specified conditions, it verifies the material's puncture resistance and insulation safety under mechanical stress to meet relevant safety standards.
Application
This equipment is suitable for testing the surface scratch resistance of the following materials and products:
- Scratch testing of accessible solid insulating parts or printed circuit boards in household appliances and similar products to ensure materials possess sufficient strength against penetration by sharp tools
- Enclosures and structural components of information technology equipment and office equipment
- Printed circuit boards (PCBs) and their insulating substrates
- Non-metallic materials such as plastics, coatings, and insulating layers
- Insulating separation zones in electrical products subjected to significant potential gradients
Applicable to product type testing, design verification, and safety performance evaluation.
