This International Standard specifies a method for the determination of sediment in crude petroleum and fuel oils by extraction with toluene. The precision applies to a range of sediment levels from 0,01 % (m/m) to 0,40 % (m/m), although higher levels may be determined.\nNOTE 1 If this International Standard is applied to crude petroleum samples containing significant amounts of salts, an overestimation of the sediment content may be obtained because a proportion of the inorganic salts may be trapped in the extraction thimble. This problem is generally not significant for crude petroleum samples containing less than 0,1 % (mlm) total salts.\nNOTE 2 For the purposes of this International Standard, the terms \"% (m/m)\" and \"% (V/V)\" are used to represent the mass and volume fractions of materials, respectively.
1.1 This test method covers the determination of sediment in crude oils and fuel oils by extraction with toluene. Note 1-Precision on recycled oils and crank case oils is unknown and additional testing is required to determine that precision. 1.2 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see 6.1 and 7.1.
