Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 3735 was developed by Technical Committee TC 28, Petroleum products and lubricants,
Subcommittee 6, Bulk cargo transfer, accountability, inspection and reconciliation.
This second edition cancels and replaces the first edition (ISO 3735:1975), of which it constitutes a technical
revision.

INTERNATIONAL STANDARD  ISO ISO 3735:1999(E)
Crude petroleum and fuel oils — Determination of
sediment — Extraction method
WARNING — The use of this International Standard may involve hazardous materials, operations and
equipment. This International Standard does not purport to address all of the safety problems associated
with its use. It is the responsibility of the user of this International Standard to establish appropriate safety
and health practices and determine the applicability of regulatory limitations prior to use.
1 Scope
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.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.
