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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10307-1 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.
This second edition cancels and replaces the first edition (ISO 10307-1:1993), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 10307-1:1993/Cor.1:1997.
ISO 10307 consists of the following parts, under the general title Petroleum products — Total sediment in
residual fuel oils:
— Part 1: Determination by hot filtration
— Part 2: Determination using standard procedures for ageing

INTERNATIONAL STANDARD ISO 10307-1:2009(E)
Petroleum products — Total sediment in residual fuel oils —
Part 1:
Determination by hot filtration
WARNING — The use of this part of ISO 10307 could involve hazardous materials, operations and
equipment. The document does not purport to address all of the safety problems associated with its
use. It is the responsibility of the user of this part of ISO 10307 to establish appropriate safety and
health practices, and determine the applicability of regulatory limitations prior to use.
1Scope
This part of ISO 10307 specifies a method for the determination of total sediment in residual fuel oils having a
2 ◦
maximum viscosity of 55 mm /s at 100 C, and for blends of distillate fuels containing residual components.
The maximum total sediment covered by the precision evaluations of this method is 0,50 % (m/m) for residual
fuels and 0,40 % (m/m) for distillate fuels containing residual components. Some fuels could exceed the
maximum filtration time specified in this method due to factors other than the presence of significant quantities
of insoluble organic or inorganic material.
1)
For the determination of sediment insoluble in toluene, see ISO 3735 .
NOTE 1 The method can also be used for the assessment of total sediment after regimes of fuel pre-treatment designed to
accelerate the ageing process (see ISO 10307-2).
NOTE 2 Significant amounts of sediment in a residual fuel oil can cause fouling of facilities for handling and present
problems in burner mechanisms. Sediment can accumulate in storage tanks, on filter screens or on burner parts, resulting
in obstruction to flow of oil from the tank to the burner.
NOTE 3 For the purposes of this International Standard, the terms “% (m/m)” and “% (V/V )” are used to represent
mass and volume fractions of a material, respectively. These expressions are deprecated under the International System
and according to ISO 31-0, Quantities and units — Part 0: General principles, which specifies that mass and volume
fractions be expressed as “mass fraction of xx %” (symbol ω) and “volume fraction of xx %” (symbol ϕ).

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
total sediment
sum of insoluble organic and inorganic material, separated from the bulk of the sample by filtration through a
specified filter, and also insoluble in a predominantly paraffinic solvent
4Principle
◦
An aliquot of the oil sample is filtered through the prescribed apparatus (Clause 6) at 100 C, and after solvent
washing and drying the total sediment on the filter is weighed. The test is carried out in duplicate.
5Materials
During the analysis, unless otherwise stated, use only reagents as specified in ISO 6353-2 and ISO 6353-3, if
listed there. If not listed, then use reagents of a recognized analytical grade.
5.1 Heptane, CH (CH ) CH .

WARNING — Heptane is a toxic volatile hydrocarbon, and shall only be used with adequate ventilation.
Avoid inhalation of vapour or mist and prolonged skin contact.
5.2 Toluene, C H CH .
6 5 3
WARNING — Toluene is a toxic, volatile hydrocarbon which is absorbed by inhaling the vapour or
through skin contact with the liquid. Use only in adequate ventilation and avoid skin contact.
5.3 Wash solvent, consisting of 85 % (V/V ) heptane (5.1) and 15 % (V/V ) toluene (5.2).
6 Apparatus
6.1 Filtration apparatus, an example of which is shown in Figure 1 and the arrangement of which is shown in
