11、 The work of preparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-gov

12、ernmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the InternationalElectrotechnical 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

13、 main task of technical committees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational Standard requires approval by at least 75 % of the member bodies casting a vote.At

14、tention is drawn to the possibility that some of the elements of this document may be the subject of patentrights. 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

15、edition cancels and replaces the first edition (ISO 10307-1:1993), which has been technicallyrevised. 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 inresidual fuel oils:

17、trationWARNING The use of this part of ISO 10307 could involve hazardous materials, operations andequipment. The document does not purport to address all of the safety problems associated with itsuse. It is the responsibility of the user of this part of ISO 10307 to establish appropriate safety andh

18、ealth practices, and determine the applicability of regulatory limitations prior to use.1ScopeThis part of ISO 10307 specifies a method for the determination of total sediment in residual fuel oils having amaximum viscosity of at , and for blends of distillate fuels containing residual components.Th

19、e maximum total sediment covered by the precision evaluations of this method is for residualfuels and for distillate fuels containing residual components. Some fuels could exceed themaximum filtration time specified in this method due to factors other than the presence of significant quantitiesof in

20、soluble organic or inorganic material.For the determination of sediment insoluble in toluene, see ISO 37351).NOTE 1 The method can also be used for the assessment of total sediment after regimes of fuel pre-treatment designed toaccelerate the ageing process (see ISO 10307-2).NOTE 2 Significant amoun

21、ts of sediment in a residual fuel oil can cause fouling of facilities for handling and presentproblems in burner mechanisms. Sediment can accumulate in storage tanks, on filter screens or on burner parts, resultingin obstruction to flow of oil from the tank to the burner.NOTE 3 For the purposes of t

22、his International Standard, the terms “ ” and “ ” are used to representmass and volume fractions of a material, respectively. These expressions are deprecated under the International Systemand according to ISO 31-0, Quantities and units Part 0: General principles, which specifies that mass and volum

23、efractions be expressed as “mass fraction of xx %” (symbol ) and “volume fraction of xx %” (symbol ).2 Normative referencesThe following referenced documents are indispensable for the application of this document.
