Standard Test Method for Sediment in Crude Oil by Membrane Filtration
4.1 A knowledge of the sediment content of crude oil is important both in refinery operations and in crude oil commerce.
1.1 This test method covers the determination of sediment in crude oils by membrane filtration. This test method has been validated for crude oils with sediments up to approximately 0.15 % by mass.
1.2 The accepted unit of measure for this test method is mass %, but an equation to convert to volume % is provided (see Note 6).
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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. For specific warning statements, see 6.1 and Annex A1.
