The work of preparing International Standards
15、 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 organizations, governmental and non-governmental, in liaison with ISO, also take p
16、art 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 given in the ISO/IEC Directives, Part 2. The main task of technical committees is to
17、 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 75 % of the member bodies casting a vote. Attention is drawn to the possibility t

ISO 21527-1 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 9, Microbiology. ISO 21527 consists of the followi
19、ng parts, under the general title Microbiology of food and animal feedings stuffs Horizontal method for the enumeration of yeasts and moulds: Part 1: Colony count technique in products with water activity greater than 0,95 Part 2: Colony count technique in products with water activity less than or e

21、servedIntroduction Because of the large variety of food and feed products, the applications of the horizontal method specified in ISO 21527 (all parts) may not be appropriate for certain products. In this case, different methods, which are specific to these products, may be used if absolutely necess
22、ary for justified technical reasons. Nevertheless, every attempt shall be made to apply the horizontal method as specified in ISO 21527 (all parts) as far as possible. When ISO 21527 (all parts) is next reviewed, account will be taken of all information then available regarding the extent to which t
23、he horizontal method has been followed and the reasons for deviations from this method in the case of particular products. 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
24、with the horizontal method as specified in ISO 21527 (all parts). It is hoped that when such standards are reviewed they will be changed to comply with ISO 21527 (all parts) so that eventually the only remaining departures from this horizontal method will be those necessary for well-established tech
