Причина отмены This test method covered 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 was not intended as part of the measured sediment, the test method was not applicable in cases where precipitated oil-soluble components will appreciably contribute to the sediment readings.

Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in December 2022.

To keep the method current, an ILS must be conducted to generate a research report and new precision statement. A communication was sent to the global ASTM community to communicate the plan to allow these methods to eventually be withdrawn. There were no responses to this communication and no volunteers to lead an ILS. Thus, the standard is withdrawn with no replacement.

Значение и использование

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.
