1. Product Function and Application
The Scratch Tester is designed to evaluate a material’s resistance to surface scratching. It is widely used for testing automotive interior components, coatings, plastics, and decorative materials.
The tester applies a controlled load through interchangeable scratch heads to create linear scratches on the specimen surface, simulating real-world damage from contact or abrasion.
After testing, scratches are visually inspected or measured microscopically to assess coating or surface durability.
This tester is highly versatile and supports major automotive standards from Honda, Nissan, and Hyundai.
