Standard Test Method for Oil Separation from Lubricating Grease During Storage
This standard is issued under the fixed designation D1742; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (ε) indicates an editorial change since the last revision or reapproval.
This test method covers the determination of the tendency of a lubricating grease to separate oil during storage in both normally filled and partially filled containers.
Standard Test Method for Oil Separation from Lubricating Grease (Conical Sieve Method)
The conical sieve method for measuring leakage from lubricating grease (commonly known as the cone bleed test) uses the same equipment as the obsolete, withdrawn FED-STD-791C (Federal Test Method (FTM) 791C) Method 321.3, Oil Separation from Lubricating Grease (Static Technique). Despite the lack of a precision statement, Method 321.3 was used for many years in specifications to evaluate the tendencies of base fluid separation from military and industrial greases. Test Method D6184 supersedes the FTM method by overcoming deficiencies of Method 321.3. It includes the procedures and precision determinations resultant from a cooperative study conducted by participating members of Subcommittee D02.G0.
This test method covers the determination of the tendency of lubricating grease to separate oil at an elevated temperature. This test method shall be conducted at 100 °C for 30 h unless other conditions are required by the grease specification.
Determination of oil separation from lubricating grease - Pressure filtration method
This standard describes a method for measuring the oil that separates from a lubricating grease under the conditions of test.
