Koehler Bench Scale Four Ball Test Technology

Introducing Koehler Bench Scale Four Ball Test Technology to Evaluate Fluids for Electric Vehicles

The continuous release of harmful carbon emissions around the world has ignited increased awareness of climate change. One of the ways that people have found effective in lowering carbon emissions is through a focus on daily transportation and switching to electric vehicles which offer many positives. This has led to increased support for the development of electric vehicles (EVs) and the necessary components needed to construct them.

Lubricants and greases are pivotal components to making an EV run efficiently. The four-ball test method is a very important test method for lubricants and greases for electric vehicles for determining the wear prevention characteristics. All of the test methods mentioned are crucial within the four-ball test and a special instrument is needed in order to measure all the properties.All of these test methods and the equipment used within them must follow the standards issued by the American Society for Testing and Materials (ASTM International).
