ASTM D4049 Water Spray off Tester for Measuring Resistance of Lubricating Grease to Water Spray

Introduction:
The operating principle of the Water Spray Off Tester is: apply lubricating grease on a stainless steel plate and use water spray under the specified test temperature and pressure. After 5min, measure the spray weight loss percentage of the grease as a measure of the water spray resistance to the grease.
