Animal feeding stuffs - Guidelines for sample preparation (ISO 6498:2012)
ISO 6498:2012 specifies guidelines for the preparation of test samples from laboratory samples of animal feeding stuffs, including pet foods.
The guidelines are overruled by special instructions and regulations for sample preparation demanded by specific analysis methods.
Futtermittel - Leitfaden für die Probenvorbereitung (ISO 6498:2012)
Diese Internationale Norm legt einen Leitfaden zur Herstellung von Untersuchungsproben aus Laboratoriums-proben von Tierfuttermitteln, einschließlich Futtermitteln für Heimtiere fest.
ANMERKUNG 1 Der Leitfaden leitet sich am häufigsten von den Richtlinien des AAFCO (en: Association of American Feed Control Officials) (Verband amerikanischer Kontrollbehörden für Futtermittel) ab (siehe Literaturhinweis [7]).
Der Leitfaden wird von speziellen Anweisungen und Vorschriften zur Probenvorbereitung aufgehoben, die durch spezifische Analysenverfahren gefordert werden.
ANMERKUNG 2 Solche Analyseverfahren werden von ISO und CEN entwickelt.
ANMERKUNG 3 Diese Internationale Norm enthält keinen speziellen Leitfaden zur Probenvorbereitung für die mikrobiologische Analyse von Mikroorganismen, wie z. B. Hefen, Bakterien und Schimmelpilze. Trotzdem sind für Mikroorganismen, die als Futtermittelzusätze (Probiotika) verwendet werden, einige wichtige Gesichtspunkte zur Proben¬vorbereitung genannt.
Aliments des animaux - Lignes directrices pour la préparation des échantillons (ISO 6498:2012)
L'ISO 6498:2012 spécifie des lignes directrices pour la préparation des échantillons pour essai d'aliments pour animaux, y compris les animaux domestiques, à partir des échantillons pour laboratoire.
Les lignes directrices sont annulées par des instructions et des règlements particuliers pour la préparation des échantillons exigés par les méthodes d'analyse spécifiques des aliments pour animaux.
Krma - Smernice za pripravo vzorca (ISO 6498:2012)
Ta mednarodni standard določa smernice za pripravo preskusnih vzorcev iz laboratorijskih vzorcev krme, vključno s hrano za hišne ljubljenčke. Posebne analizne metode vključujejo posebna navodila in predpise, ki se uporabljajo namesto teh smernic.

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 6498 was prepared by the European Committee for Standardization (CEN) Technical Committee TC 327,
Animal feeding stuffs — Methods of sampling and analysis, in collaboration with ISO Technical Committee
TC 34, Food products, Subcommittee SC 10, Animal feeding stuffs, in accordance with the Agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 6498:1998), which has been technically revised.
This corrected version of ISO 6498:2012 incorporates the following correction: in 7.1, paragraph 4, the phrase
“particle sizes below 4 mm ± 2 mm (4 mm to 6 mm) can be” has been substituted by “particle sizes of 4 mm to
6 mm can be”.
