33、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. Inte
34、rnational 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 th
35、e 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 b
36、y 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 10307-2 was prepared by Technical Committee
37、ISO/TC 28, Petroleum products and lubricants. This second edition cancels and replaces the first edition (ISO 10307-2:1993) which has been technically revised.

39、n that the precipitation of asphaltenes form a residual fuel oil in the form of sediment may occur during storage and handling. Such sediment may cause severe difficulties, and in extreme cases can render the fuel unfit for use. Once out of solution, it is extremely difficult to repeptize the asphal
40、tenes into their original state. Fuel pre-treatment designed to accelerate the ageing/sedimentation process, followed by filtration, is a well- established technique for testing whether sediment from residual fuel oils will precipitate during storage and handling. This could involve thermal ageing (
41、heating to a specified temperature for a specified time) or chemical ageing (addition of a specified amount of a normal alkane to test whether the balance between the required aromaticity of the asphaltenes and the available aromaticity of the oil phase is disturbed to the extent that asphaltene pre
42、cipitation occurs). A means of predicting the presence of a reserve of stability to sedimentation in residual fuel oil during storage and handling is thus a useful tool in the petroleum products industry.

This International Standard does not purport to address all of the safety problems associated with its use. It is the resp
45、onsibility 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 part of ISO 10307 specifies two procedures for accelerated ageing of residual fuel oils which, combined with
46、 the hot filtration method specified in 10307-1, permit the prediction of fuel oil stability to sedimentation during storage and handling.
