Skimmed milk, whey and buttermilk - Determination of fat content - Gravimetric method (Reference method)(ISO 7208:2008)

ISO 7208|IDF 22:2008 specifies the reference method for the determination of the fat content of liquid skimmed milk, whey and buttermilk. It is a particularly accurate gravimetric method especially for the purpose of establishing the operating efficiency of cream separators.
ISO 7208|IDF 22:2008 also specifies the reference method for establishing correction tables for procedures with skimmed milk butyrometers.

Magermilch, Molke und Buttermilch - Bestimmung des Fettgehaltes - Gravimetrisches Verfahren (Referenzverfahren) (ISO 7208:2008)

Diese Internationale Norm legt das Referenzverfahren für die Bestimmung des Fettgehaltes von flüssiger Magermilch, Molke und Buttermilch fest. Dabei handelt es sich um ein besonders genaues gravimetrisches Verfahren, insbesondere um die Wirksamkeit von Rahmseparatoren festzustellen.
Diese Internationale Norm legt außerdem das Referenzverfahren zum Erstellen von Korrekturtabellen für Bestimmungen mit Magermilch-Butyrometern fest.
ANMERKUNG   Das in ISO 1211|IDF 1 [2] festgelegte Verfahren ist geeignet, falls eine hohe Bestimmungsgenauigkeit nicht erforderlich ist.

Lait écrémé, sérum et babeurre - Détermination de la teneur en matière grasse - Méthode gravimétrique (Méthode de référence) (ISO 7208:2008)

L'ISO 7208|FIL 22:2008 spécifie la méthode de référence pour la détermination de la teneur en matière grasse du lait liquide écrémé, du sérum et du babeurre. Il s'agit d'une méthode gravimétrique particulièrement précise en vue de déterminer l'efficacité de l'opération d'écrémage.
L'ISO 7208|FIL 22:2008 spécifie également la méthode de référence permettant d'établir des tables de correction pour les techniques utilisant les butyromètres à lait écrémé.

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 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 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. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7208⎪IDF 22 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 5,
Milk and milk products, and the International Dairy Federation (IDF). It is being published jointly by ISO and
IDF.
This third edition of ISO 7208⎪IDF 22 cancels and replaces the second edition (ISO 7208:1999), of which it
constitutes a minor revision.

Foreword
IDF (the International Dairy Federation) is a non-profit organization representing the dairy sector worldwide.
IDF membership comprises National Committees in every member country as well as regional dairy
associations having signed a formal agreement on cooperation with IDF. All members of IDF have the right to
be represented at the IDF Standing Committees carrying out the technical work. IDF collaborates with ISO in
the development of standard methods of analysis and sampling for milk and milk products.
Draft International Standards adopted by the Action Teams and Standing Committees are circulated to the
National Committees for voting. Publication as an International Standard requires approval by at least 50 % of
the IDF National Committees casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. IDF shall not be held responsible for identifying any or all such patent rights.
ISO 7208⎪IDF 22 was prepared by the International Dairy Federation (IDF) and Technical Committee
ISO/TC 34, Food products, Subcommittee SC 5, Milk and milk products. It is being published jointly by IDF
and ISO.
All work was carried out by the Joint ISO-IDF Action Team Fat of the Standing Committee on Main
components in milk under the aegis of its project leader, Mr G.J. Beutick (NL).
