(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 can be used on any grease with a worked penetration (Test Methods D217) greater than 220 mm/10 (NLGI Consistency Number 3 or softer). However, no precision data exists for greases with a penetration greater than 340 mm/10 (softer than NLGI Consistency Number 1).
1.3 The values stated in SI units are to be regarded as standard. The term 60 mesh is used to describe the wire mesh used. This unit was described in the withdrawn E437 standard and there is no exact metric equivalent.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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cone bleed test) uses the same equipment as the obsolete, withdrawn FED-STD-791C (Federal Test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
