IS 1448 : Part 67 : 2020 Methods of Test for Petroleum and its Products [ P : 67 ] Determination of Foaming Characteristics of Lubricating Oils
Revised Standard from Last Update.
1. SCOPE
This standard [P : 67] specifies a method for the determination of foaming characteristics of lubricating oils at specified moderate temperatures. It is applicable to lubricants which may or may not contain additives to modify or suppress the tendency to form stable foams. The ratings used to describe the foaming tendency and/ or stability are empirical.
NOTE - This method may be used to indicate potential problems in lubrication, cavitation and loss in systems where foam formation adversely affects equipment operation.
