12、ndards 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 or
13、ganizations, 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 give
14、n 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 7
15、5 % 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 13319 was prepared by Technical Committee ISO/TC 24, Sie
16、ves, sieving, and other sizing methods, Subcommittee SC 4, Sizing by methods other than sieving. This second edition cancels and replaces the first edition (ISO 13319:2000), which has been technically revised.

18、lectrical sensing zone method. The method measures pulse heights and their relationship to particle volumes or diameters, and it reports in the range from approximately 0,4 m to approximately 1 200 m. It does not address the specific requirements of the measurement of specific materials. However, gu
19、idance on the measurements of conducting materials such as porous materials and metal powders is given. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the
20、latest edition of the referenced document (including any amendments) applies.
