Test Procedures
Sample Preparation:
Select a representative sample of plastic, film, or coated material.
Inspect the surface to ensure it is free of contamination or defects that may affect the test.
Setup:
Install the sample securely in the sample holder.
Select the appropriate scratch tip and load according to the test standard.
Program scratch distance, speed, and load using the touch screen interface.
