ABREX®
Chemo-mechanical Hand-Abrasion
Basic Functions
Damage to a surface by the human hand is one of the main reasons for the sustained disturbance of a product’s valence. ABREX® tests the finished product or the lab sample regarding high-complex viscoelastic process of hand-abrasion and its chemical environment.
Advantages:
- Reproducible results due to standardised test procedures
- Practice-oriented testing by chemo-mechanical abrasion
- Universal use by flexible unit design
Soft chemo-mechanical hand-abrasion tests acc. to:
- DIN EN 60068-2-70 / IEC 68-2-70
- BMW GS 97034 / GS 97045
- Daimler DBL 7384
- Ford WSS-M2P188-A1
- EWIMA specification
- Sony Ericsson 45/152 41-FEA 202 8139 Uen
as well as further company standards.
