ASTM D2273 – Standard Test Method for Trace Sediment in Lubricating Oils (Withdrawn 2023)
Description:
Significance and Use
4.1 This test measures the trace level amount of sediment that is naphtha-insoluble and can be separated by centrifuging. Excessive amounts of sediment in oil could lead to system malfunction in critical applications.
Scope
1.1 This test method covers the determination of trace amounts (less than 0.05 % by volume) of sediment in lubricating oils. Since oil-soluble material precipitated by the specified solvent is not intended as part of the measured sediment, the test method is not applicable in cases where precipitated oil-soluble components will appreciably contribute to the sediment readings.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
