For evaluation of the resistance of a lubricating grease to washout by water from a bearing, when tested at 38 and 79°C (100 and 175°F) under the prescribed laboratory conditions. It is not to be considered the equivalent of service evaluation tests. This test method may not be suitable for some greases containing highly volatile components

Made of stainless steel with of a thermostatic cabin with electric stainless steel heater controlled by a digital thermoregulator, digital timer, two bearings type 6204, a thermometer determining water temperature in the cabin, an electric motor with direct coupling to the pump and drive belt for the shaft pulley 600 rpm, a bearings block, a flowmeter measuring water delivery, delivery and back-flow gates with by-pass and regulator valves.

- Temperature: from ambient to 90°C (194°F)
- Stability: ±1°C
- Power supply: 220V 50/60Hz
