37、l 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 for which a technical committee has beenest

38、ablished 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 all matters of electrotechnical standardiz

39、ation. 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 Standardsadopted by the technical committees are circulated to the member bodies for voting

40、. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO Publicly

41、Available Specification (ISO/PAS) represents an agreement between technical experts inan ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement betwee

42、n the members of a technicalcommittee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for afurther three years, revised to become an Internation

43、al Standard, or withdrawn. If the ISO/PAS or ISO/TS isconfirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.

46、ights reserved vIntroduction Because of the large variety of food and feed products, ISO 10272 may not be appropriate in every detail forcertain products, and for some other products it may be necessary to use different methods. Nevertheless, in all cases, every attempt should be made to apply ISO 1

47、0272 as far as possible, anydeviations being made only if absolutely necessary for technical reasons.When ISO 10272 is next reviewed, account will be taken of all information then available regarding the extentto which the methods have been followed and the reasons for deviations from it in the case

48、 of particularproducts. The harmonization of test methods cannot be immediate and, for certain groups of products,International Standards and/or national standards may already exist that do not comply with ISO 10272. It ishoped that, when such standards are reviewed, they will be changed to comply w

49、ith ISO 10272, so that eventually the only remaining departures are those necessary for well-established technical reasons.
