Tested product
MATHY® WKA additive ISO VG 320
Testing institute
Hamburg University of Technology Institute of Product Development and Design Engineering
Conclusion
The addition of MATHY® WKA ISO VG 320 gear oil additive to the commercially available gear oil of viscosity class ISO VG 320 leads to:
- a slight increase in the mean coefficient of friction by +3%.
- a significant reduction in the wear volume by -80%.
a significant increase in the critical high pressure pHD, crit (critical Hertzian pressure pHertz,crit) by +13%.

Test procedure - Designation
The MPH test procedure (mechanical testing of hydraulic fluids) at the Hamburg University of Technology is a new test procedure for testing the lubricity of hydraulic fluids.
Testverfahren – Ziel
To obtain a statement on the effectiveness of the MATHY® WKA ISO VG 320 additive added to the gear oil in terms of lubricity and wear protection.
Testverfahren – Beschreibung
The testing device for mechanical testing (MPH test method) of hydraulic fluids, transmission and engine oils is suitable for mapping the tribological situations that occur in machines. At the same time, it is designed so simply that it can work with test specimens of simple geometry.
