Features

Multiple test functions integrated into a single system

Scratch resistance testing in accordance with ISO DIS 12137-2. with scratch size evaluated by microscopic observation

Pencil hardness–type testing based on JIS K 5600. using a 45° inclined pencil to compare surface hardness

Surface smoothness measurement by recording sliding resistance of a flat fixture to calculate static and dynamic friction

Optional friction and wear analysis software enables quantitative evaluation of scratch resistance based on measured resistance

Accurate determination of critical loads corresponding to surface indentation and cracking through resistance variation analysis

Test Procedures

Secure the test specimen firmly on the moving stage.

Select and install the appropriate scratch needle or test fixture.

Choose the required continuous or fixed load range.

Set the sliding speed and travel distance.

Perform system checks and ensure overload protection is active.

Start the test to apply progressive load during linear motion.

Observe scratch formation and record resistance data for analysis.
