Microbiology of food and animal feeding stuffs - Specific requirements and guidance for proficiency testing by interlaboratory comparison (ISO/TS 22117:2010)
ISO/TS 22117:2010 gives requirements and guidance for the organization of proficiency testing schemes for microbiological examinations of: a) food and beverages; b) animal feeding stuffs; c) food production environments and food handling; d) primary production stages.
ISO/TS 22117:2010 is also potentially applicable to the microbiological examination of water where water is either used in food production or is regarded as a food in national legislation.
ISO/TS 22117:2010 relates to the technical organization and the implementation of proficiency testing schemes, as well as the statistical treatment of the results of microbiological examinations.
ISO/TS 22117:2010 is designed for use with ISO/IEC 17043 and ISO 13528, and deals only with areas where specific or additional details are necessary for proficiency testing schemes dealing with microbiological analyses for the areas specified in the first paragraph.

Die vorliegende Technische Spezifikation enthält Anforderungen und eine Anleitung für die Organisation von
Eignungsprüfungsprogrammen für die mikrobiologische Untersuchung von:
a) Lebensmitteln und Getränken;
b) Futtermitteln;
c) Umgebung der Lebensmittelproduktion und Handhabung von Lebensmitteln;
d) Primärproduktion.
Diese Technische Spezifikation ist potentiell auch auf die mikrobiologischen Untersuchungen von Wasser
anwendbar, wenn Wasser entweder in der Lebensmittelproduktion verwendet oder in der nationalen Gesetzgebung
als Lebensmittel angesehen wird.
Diese Technische Spezifikation bezieht sich auf die technische Organisation und die Umsetzung von
Eignungsprüfungsprogrammen sowie auf die statistische Behandlung von Ergebnissen mikrobiologischer
Untersuchungen.
Diese Technische Spezifikation ist in Verbindung mit ISO/IEC 17043 und ISO 13528 anzuwenden und
behandelt nur die Gebiete, in denen spezifische oder zusätzliche Einzelheiten für Eignungsprüfungsprogramme
notwendig sind, die sich mit mikrobiologischen Untersuchungen in den im ersten Absatz aufgeführten
Bereichen befassen.
Microbiologie des aliments - Exigences spécifiques et lignes directrices pour les essais d'aptitude par comparaison interlaboratoires (ISO/TS 22117:2010)
L'ISO/TS 22117:2010 fournit des exigences et des recommandations relatives à l'organisation de programmes d'essai d'aptitude pour les examens microbiologiques concernant: a) les aliments et les boissons; b) les aliments pour animaux; c) les environnements de production des aliments et la manipulation de ces aliments; d) les étapes de production primaire.
Éventuellement, l'ISO/TS 22117:2010 peut également s'appliquer à l'examen microbiologique de l'eau si celle-ci est utilisée dans la production alimentaire ou si la législation nationale la considère comme un aliment.
L'ISO/TS 22117:2010 concerne l'organisation technique et la mise en œuvre de programmes d'essai d'aptitude et également le traitement statistique des résultats des examens microbiologiques.
L'ISO/TS 22117:2010 est destinée à être utilisée avec l'ISO/CEI 17043 et l'ISO 13528 et ne traite que des domaines où des détails spécifiques ou supplémentaires sont nécessaires pour les programmes d'essai d'aptitude traitant des analyses microbiologiques pour les domaines spécifiés dans le premier alinéa.

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.
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 Available Specification (ISO/PAS) represents an agreement between technical experts in
an 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;
⎯ ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee 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 a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
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/TS 22117 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 9,
Microbiology.
