Fingertip Hand Abrasion Tester

Functionality of a product is considered as a matter of course, so the perception of quality is determined primarily by the visual appearance. Damage to a surface by the human hand is one of the main reason for disturbance of the products quality perception.

The hand abrasion is a very complex chemical and mechanical combination. By touching a surface the human hand performs a mechanical strike followed by a push-slide force. The human hand consists of a visco elastic material containing a rough and structured surface. In addition, sweat or hand cream creates a severe chemical environment.

Hand Abrasion Tester / soft-chemo-mechanical fingertip & hand abrasion tester is designed to do real life testing of finished products or lab samples in regards of resistance to hand abrasion. The set-up of it is exactly reproducing the complex chemo mechanical system of the human hand abrasion according to international standards.

The flexible design of the tester allows various options and delivers reproducible results.

FAQ

(1)What types of products require fingertip abrasion testing?

Products frequently touched by users, such as vehicle switches, appliance panels, keyboards, buttons, and coated handles, require this type of evaluation. The test helps determine whether printed markings, coatings, and decorative surfaces can maintain appearance during daily use.

(2)What factors can affect surface abrasion resistance during testing?

Surface material, coating type, printing technology, contact pressure, rubbing distance, and chemical exposure can influence results. The tester allows users to simulate different conditions by adjusting load, abrasion materials, and optional liquid media.

(3)How does this test simulate real human hand contact?

The method combines mechanical rubbing with optional chemical influences such as artificial sweat or hand cream. It reproduces common user interactions including pressing, sliding, and repeated touching to evaluate realistic surface durability.

(4)Which standards are commonly used for hand abrasion testing?

Testing is commonly performed according to IEC 60068-2-70, EN 60068-2-70, and DIN 60068-2-70, which define methods for evaluating abrasion damage of markings and lettering caused by finger and hand rubbing.

(5)What should be considered when selecting this abrasion testing equipment?

Users should consider the tested material, required abrasion method, load range, cycle requirements, and whether chemical simulation is needed. A flexible system with multiple abrasion options can better match different product durability evaluations.
