ASTM D4310 Standard Test Method for Determining Mud and Corrosion Tendency of Disturbed Mineral Oils

EUROLAB laboratory provides testing and compliance services within the scope of ASTM D4310 standard. This test method covers and is used to evaluate the tendency of hindered mineral oil-based steam turbine lubricants and mineral oil-based antiwear hydraulic oils to corrode the copper catalyst metal in the presence of oxygen, water and copper and to form sludge during oxidation.

This test method is a modification of test method D943, in which the oxidation stability of oils of the same type is determined by monitoring the acid number of the oil. The number of test hours required for the oil to reach 2,0 mg KOH/g acid number is the oxidation life.

Procedure A of this test method requires determining and reporting the weight of the sludge and the total amount of copper in the oil, water and sludge phases. Procedure B requires only sludge determination. Acid number determination is optional for both procedures.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
