ASTM D6184 Standard Test Method for Oil Separation from Lubricating Grease

    ASTM D6184 Introduction

    ASTM D6184 evaluates the propensity of lubricating grease to separate oil when exposed to elevated temperatures. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM D6184 tests for our clients. It is typically conducted at 100°C for 30 hours, although the grease standards may specify different conditions. Greases with a worked penetration greater than 220 mm ⁄10 can undergo this test.

    ASTM D6184 Test Method

    Heating the SampleThe procedure involves placing the measured sample in a cone-shaped wire cloth filter and then suspending it in a beaker. The setup is heated under static conditions for the duration and temperature recommended by ASTM D6184. Unless specified otherwise in the grease specification, the sample is typically subjected to standard conditions of 100 ± 0.5°C for 30 ± 0.25 hours.
    Weighing the oilSubsequently, the separated oil is carefully weighed and expressed as a percentage of the test sample’s original mass.

    D6184 Equipment and Sample Preparation

    Specimen DetailThe conical sieve method is utilized to measure leakage from lubricating grease.
    Specimen SizeIn the ASTM D6184 test method, lubricating grease serves as the test specimen. It is examined for any indications of non-homogeneity, such as oil separation, phase shifts, or gross contamination. A fresh sample is obtained for testing to see if any abnormal conditions are detected.

    D6184 Test Result and Interpretation

    The ASTM D6184 test method, a standard procedure, evaluates the tendency of lubricating grease to separate oil when subjected to elevated temperatures. By employing the conical sieve method, this test assesses the extent of oil separation, which can impact the grease’s performance and consistency.  These results help ensure product quality, guide specifications, and inform quality control measures in industries reliant on effective lubrication systems.

    ASTM D6184 is related to tests, including ASTM D217 for cone penetration of lubricating grease, ASTM D1742 for oil separation from lubricating grease, and ASTM E437 for industrial wire-cloth and screen specifications.

    Use of D6184  in Various Industries

    It is important in the automotive, aerospace, and manufacturing industries for maintaining the consistency and performance of lubricating greases. It prevents excessive oil separation and ensures that grease can withstand extreme conditions.

    Materials Commonly Tested with D6184 

    Standard is usually used for lubricating greases that are used in high-performance machinery and cars. Lubricating greases in such vehicles and machinery are tested for their resistance to oil separation, which is essential for performance and longevity, and they are formulated with various base oils.

    Importance of D6184

    The standard is an essential technique for quality control and new product formulation in lubricating grease-oriented industries. It measures oil separation, ensures performance specifications, and evaluates the lifespan as well as reliability of grease, which ensures a reduction of machinery failure risks because of lubrication breakdown.
