The work of preparing International Standards is normally carried out through I
9、SO 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 organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates
10、closely with the International Electrotechnical 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.
11、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 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this d
12、ocument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2254 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 7, Spices and condiments. This second edition cancels and replaces the first edition (I
13、SO 2254:1980), of which it constitutes a minor revision.
