ABREX®-STANDARD
Human fingertip abrasion & hand abrasion tester with true simulation
With our 30-year experience and a full study of human physiology, it is proved that a
DYNAMIC PNEUMATIC ACTUATION is the best and most efficient way to simulate human finger & hand abrasion.
ABREX® is capable of translating the complex human fingertip and hand motions into a standardized testing machine which complies with DIN EN 60068-2-70.
Compared with other systems which involve either linear drive, or gear system, only ABREX® can simulate the human fingertip and hand movement.

Description
ABREX®-ABRASION, is a soft-chemo-mechanical fingertip & hand abrasion. The simulated wear pattern matches reality with 99% accuracy. It is a highly complex abrasion process which involves:
• A 45° angle impact driven by a dynamic pneumatic cylinder attached with a viscoelastic fingertip under a defined load;
• Then a friction rubbing or tumbling motion between the sample and a textile containing dirt, dandruff, oil, sweat or various types of testing liquids;
• Followed by a retraction movement with or without the contact at the surface depending on the application.

ABREX® can be upgraded to ABREX®-A & ABREX®-D & ABREX®-E respectively.
* ABREX®-A can run both standard abrasion test and special “swiping mode” with test condition of friction
path of 20mm @ 5N @ 2Hz. Other frequency, friction path and load can also be achieved upon request.

Application
The special abrasion type, namely, ABREX®-ABRASION, is a soft-chemo-mechanical fingertip & hand abrasion tester.
It has been widely used for any consumer product’s durability quality control.
Due to the regular interaction between human fingertips and hands on the surface of consumer products, this special ABREX®-ABRASION occurs unavoidably, especially under additional chemical environments including heat, humidity, chemical stress and so on.
Targeted industries include automotive, display, electronics, white goods, jewelry and so on. Detailed application notes could be accessed by contacting us.
