The work of preparing International Standards is normally carried out through ISO technical committees. Each membe
8、r body interested in a subject for 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 Elec
9、trotechnical 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 main task of technical committees is to prepare International Standards. Draft International Standards adopted
10、 by the technical committees are circulated to the member bodies for voting. Publication as an International 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 document may be the subject of patent r
11、ights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 3632-1 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 7, Spices, culinary herbs and condiments.This second edition cancels and replaces ISO/TS 3632-1:2003, which has been technic
12、ally revised.ISO 3632 consists of the following parts, under the general title Spices Saffron (Crocus sativus L.): Part 1: Specification Part 2: Test methodsISO 3632-1:2011(E) ISO 2011 All rights reserved iiiBS ISO 3632-1:2011BS ISO 3632-1:2011INTERNATIONAL STANDARD ISO 3632-1:2011(E)Spices Saffron
