fingertip hand abrasion tester
Application
The Fingertip & Hand Abrasion Tester simulates real-life hand abrasion to evaluate the durability and quality perception of product surfaces. This is critical because damage caused by human touch—through mechanical strike, push-slide force, and chemical interaction with sweat or hand creams—can affect perceived quality. The tester is widely used in the automotive industry for printed switches and door handle coatings, in white goods for printed and painted surfaces, and in the computer industry for keyboards and mice. It is suitable for finished products or lab samples, providing reproducible results that reflect real-life hand interactions.
Standards
The instrument simulates human skin abrasion and dirt/soiling effects according to international standards:
ISO 12947-1 / IEC 68-2-70 – Simulation of human skin abrasion
DIN 60068-2-70 / EN 60068-2-70 – Mechanical and chemical hand abrasion simulation
ISO 105 E04 / DIN 53160-2 – Artificial sweat testing
Other optional chemical and mechanical standards available on request, including hand cream and sun lotion testing.

FAQ
1. What is the Fingertip & Hand Abrasion Tester?
It is an advanced testing instrument designed to simulate the mechanical and chemical effects of human hand abrasion on product surfaces, reproducing push-slide and rubbing forces as well as sweat or lotion exposure.
2. What is the purpose of this tester?
The instrument assesses the durability and resistance of materials to hand-induced wear, which directly impacts perceived quality in automotive parts, white goods, electronics, and consumer products.
3. Why is this product important?
Hand abrasion is a major factor in surface damage and quality perception. By accurately simulating real-life hand interactions, this tester helps manufacturers ensure product durability, reduce customer complaints, and improve surface performance.
4. What can this tester measure?
It can measure abrasion resistance of printed markings, painted or coated surfaces, plastic parts, leather, and other soft to semi-rigid materials, under various mechanical loads and chemical exposures.
5. How does the Fingertip & Hand Abrasion Tester work?
The tester applies a controlled normal load through a friction path while moving cyclically. Abrasion pads or custom friction surfaces interact with the sample while chemical media such as artificial sweat or hand cream are applied cyclically. Test parameters including load, stroke length, and number of cycles are fully adjustable, ensuring repeatable and accurate simulation of hand abrasion conditions.
