Optionally co-design standards:
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.
NOTE 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 % (m/m) total
salts.
NOTE 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.
