'How do you interpret the results of a DIN ISO 6614 demulsibility test for turbine oils?

摘要

"I'm checking a data sheet of a proposed lubricant's separation power of water and oil, and the test yields a value of less than 30. Is this a good result for the test?" The ability for water and oil to separate, also known as demulsibility, is an important factor in many industrial oils. The effects of water in oil can be very detrimental to machine surfaces and can greatly reduce machine life. This oil property must be closely monitored, especially in areas where water ingression is common (steam turbines, paper machines, etc.).
