9、deration 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 com
10、mittee. 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 accord
11、ance 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 require
12、s 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 Technica

17、s, 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 pri
18、or to use. 1Scope This part of ISO 10307 specifies a method for the determination of total sediment in residual fuel oils having a maximum viscosity of at , and for blends of distillate fuels containing residual components. The maximum total sediment covered by the precision evaluations of this meth
19、od is for residual fuels and 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. For the determination of sedimen
20、t insoluble in toluene, see ISO 37351). NOTE 1The 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 2Significant amounts of sediment in a residual fuel oil can cause fouling of facilities
21、 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 3For the purposes of this International Standard, the terms “” and “” are used to represe
22、nt 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 ) and “
23、volume fraction of xx %” (symbol ). 2Normative references The following referenced documents are indispensable for the application of this document.

Allow to cool in the cooling vessel (6.14) to room temperature for . Weigh each filter to the nearest . NOTE 1For convenience, the filters can be
42、 placed on numbered small dishes (6.6) during drying and cooling. NOTE 2It has been shown that the same level of results is achieved by the use of a fine wire mesh support screen (see Figure 1) in combination with a third, disposable filter. This third filter can be placed below the two test filters
43、 on the support screen and the same pre-drying regime followed as for the test filters, but without weighing the third filter before placement, discarding it when filtration is complete. The glass-fibre filters are fragile, and need to be handled with care. Before use, check each against a backgroun
