Glass Scratch/Abrasion Tester
The Glass Scratch/Abrasion Tester is used to test the scratch and abrasion resistance of glass. This instrument uses a counter to set the number of rubbing cycles and a speed controller to adjust the operating speed of the rubbing head to meet the customer's actual testing needs. During the test, a 10mm*10mm rubbing head equipped with steel wool is used. Adjustable weights adjust the pressure load of the rubbing head to rub the glass. After the test, the sample is removed and its scratch and abrasion resistance is evaluated.
Applications
Automotive Glass: Assesses windshield durability against environmental wear.
Consumer Electronics: Tests smart screens, tablet covers, and display panels.
Architectural Glass: Validates window and facade materials for long-term performance.
Medical Devices: Ensures compliance with biocompatibility standards (e.g., ISO 10993-7).

Test Procedures
Place the cut sample on the sample clamping platform and clamp it securely.
Fix the weights, ensuring full contact between the friction head and the sample, and tighten the device.
Turn on the machine and select the desired test mode (specified number of times or continuous operation). Then set the desired number of friction cycles and the desired operating speed.
Turn on the speed controller switch and press the start button; the equipment will begin operation.
After the test, record the surface friction of the sample and assign a relevant rating.
