There are many methods in Surface Test. The methods are - Tribology, Abrasion, Adhesive strength, Scratch test, Friction, Wear test.

Tribometer serve to characterize friction and wear behavior of materials. They are the basis for tribologically oriented development of materials and lubricants and for quality assurance. With these Tribometer materials as well as lubricants can be tested under complex and application orientated tribological test conditions.

Computer aided friction and wear measurements can be performed according to all normal ASTM and DIN standards.

The test procedure is to judge abrasion resistance of paintings and similar coatings as well as of print colours. The tester can be used for all kinds of surfaces which are exposed to smooth mechanical loads, e.g. friction with clothes or paper of office equipment, control units, or painted edges or buttons.
The abrasion resistance can be tested on all nearly flat surfaces.

Scratch Tester for Plastic Surfaces to check the resistance of plastic surfaces. Scratch Tester "Artificial Finger-Naill", it has to be simulated how touching of fingernails may cause scratches on a dashboard or on plastic glass surfaces. The RPG friction tester is used for determining the friction behavior of a plastic foil relative to a second friction component (second plastic foil, metal or similar). The tester can be used for all kinds of surfaces, which are exposed to smooth mechanical loads, e.g. friction with clothes or paper of office equipment, control units, or painted edges or buttons.

Wear Test, rig for determining of dynamical characteristics of cole brushes on metal surfaces. Small cole brushes as used in electrical motors are tested.

Following measuring values are determined:

- Contact voltage drop at cole brushes charged with current

- Friction coefficient of cole brushes against steel

- Current distribution of the brushes

- Temperature of the steel

- Velocity of the steel
