Standard Test Method for Demulsibility Characteristics of Lubricating Oils
Standard Test Method for Demulsibility Characteristics of Lubricating Oils
SIGNIFICANCE AND USE 5.1 This test provides a guide for determining the demulsibility characteristic of lubricating oils that are prone to water contamination and may encounter the turbulence of pumping and circulation capable of producing water-in-oil emulsions. SCOPE 1.1 This test method covers the measurement of the ability of oil and water to separate from each other. It is intended for use in testing medium and high-viscosity lubricating oils. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. 1.4 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.
ASTM D2711-22, "Standard Test Method for Demulsibility Characteristics of Lubricating Oils," specifies a laboratory procedure for measuring the ability of oil and water to separate after being mixed under controlled conditions. This method is crucial for evaluating the demulsibility-or water-separation characteristics-of medium and high-viscosity lubricating oils that may be exposed to water contamination and agitation during use. The standard helps manufacturers, formulators, and users determine how well oils resist forming stable water-in-oil emulsions, which can negatively impact lubrication, equipment life, and performance.
This ASTM D2711 test method is widely utilized in industries such as:
