18、 reservedv 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 fo
19、r 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
20、all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International
21、 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 part of ISO 3890 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Internation
22、al Standard ISO 3890-2 was prepared by Technical Committee ISO/TC 34, Agricultural food products, Subcommittee SC 5, Milk and milk products, in collaboration with the International Dairy Federation (IDF) and AOAC International, and will also be published by these organizations. ISO 3890 consists of
23、the following parts, under the general title Milk and milk products Determination of residues of organochlorine compounds (pesticides): Part 1: General considerations and extraction methods Part 2: Test methods for crude extract purification and confirmation Copyright International Organization for
