(Test Method)Standard Test Method for Oil Separation from Lubricating Grease (Conical Sieve Method)
Standard Test Method for Oil Separation from Lubricating Grease (Conical Sieve Method)
SIGNIFICANCE AND USE
5.1 When lubricating grease separates oil, the residual material may change in consistency, which can affect the ability of the product to function as designed. Test results obtained with this procedure are not intended to predict oil separation tendencies of grease under dynamic service conditions.
5.2 This test method is used for specifications and quality control.
SCOPE
1.1 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.
1.2 This test method is suitable for use with most all greases, but the test precision was established using greases having a worked penetration (Test Methods D217) greater than 220 (NLGI No. 3 grade) and less than 340 (NLGI No. 1 grade).
1.3 The values stated in SI units are to be regarded as standard. The term 60 mesh was originally described in the now withdrawn E437 standard. It is used to describe the wire mesh because there is no exact metric equivalent.
1.4 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
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cone bleed test) uses the same equipment as the obsolete, withdrawn Federal Test Method (FTM)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 of Committee D02.
