Recent work of the global SRV working group and the development trend of SRV standards
- „Cliff“-testing by using SRV
The identification in engine or gear tests of the induction time or off-set point („cliff“), after which wear and friction increased.
“Cliff” testing as auxiliary method supports the interpretation of engine tests, as it enhances the values of expensive engine tests, because it enables correlations between friction & wear, either from engine or in SRV tests, with additive depletion, oxidation, viscometrics and dispersancy/detergency.
Oil samples taken in discrete intervals and “Cliff” tested monitors the evolution of tribological and functional properties versus engine running time. “Cliff” testing by using SRV is a purposeful tool in order to secure and accelerate metallurgical developments and the development of lubricant formulations.
