Cereals and cereal products - Sampling (ISO 24333:2009)
ISO 24333:2009 specifies requirements for the dynamic or static sampling, by manual or mechanical means, of cereals and cereal products, for assessment of their quality and condition.
It is applicable to sampling for the determination of heterogeneously distributed contaminants, undesirable substances, and parameters usually homogeneously distributed like those used to assess quality or compliance with specification.
It can be used to determine insects in a grain lot.
It is applicable to sampling for assessment of the quality and condition of lots of genetically modified organisms (GMO) but is inappropriate for the determination of the presence of adventitious genetically modified material in non-GM product.
It is not applicable to seed grain.
Getreide und Getreideerzeugnisse - Probenahme (ISO 24333:2009)
Diese Internationale Norm legt Anforderungen an die dynamische oder statische Probenahme von Getreide und Getreideerzeugnissen mit manuellen oder mechanischen Mitteln zwecks Einschätzung der Qualität und Beschaffenheit fest.
Sie ist für die Probenahme zur Bestimmung von heterogen verteilten Kontaminanten, unerwünschten Substanzen und üblicherweise homogen verteilten Parametern, wie jene, die der Bewertung der Qualität oder der Übereinstimmung mit der Spezifikation dienen, anwendbar.
Sie kann für den Nachweis von Insekten in einer Getreidepartie angewendet werden.
ANMERKUNG 1 Um den Befallsdruck zu beurteilen, sind andere Verfahren, wie z. B. das Aufstellen von Fallen während der Getreidelagerung, besser geeignet.
Sie ist für die Probenahme zur Beurteilung der Qualität und des Zustands von Partien gentechnisch veränderter Organismen (GVO) anwendbar. Sie ist jedoch nicht geeignet, um die zufällige Anwesenheit von gentechnisch verändertem Material in nicht gentechnisch veränderten Erzeugnissen zu bestimmen.
Diese Internationale Norm ist nicht für Saatgetreide geeignet.
ANMERKUNG 2 Die Probenahme von Saatgetreide wird durch Regeln der ISTA (International Seed Testing Association) abgedeckt.
ANMERKUNG 3 Zum Zeitpunkt der Veröffentlichung gibt es keine Studie, die die Einbeziehung der Probenahme von nicht gentechnisch veränderten Erzeugnissen unterstützt, um zufällige GV Anwesenheit innerhalb des Anwendungs¬bereichs dieser Internationalen Norm zu bestimmen.
Céréales et produits céréaliers - Échantillonnage (ISO 24333:2009)
L'ISO 24333:2009 spécifie des exigences relatives à l'échantillonnage dynamique ou statique, par des moyens manuels ou mécaniques, des céréales et produits céréaliers, en vue de l'évaluation de leur qualité et de leur état.
Elle est applicable à l'échantillonnage réalisé en vue de la détermination de contaminants répartis de façon hétérogène, de substances indésirables et de paramètres généralement répartis de façon homogène comme ceux utilisés pour évaluer la qualité ou la conformité à une spécification.
Elle peut être utilisée afin de déterminer l'infestation par des insectes d'un lot de grains.
Elle est applicable à l'échantillonnage réalisé en vue de l'évaluation de la qualité et de l'état des lots d'organismes génétiquement modifiés (OGM) mais n'est pas appropriée pour déterminer la présence fortuite d'organismes génétiquement modifiés dans des produits non génétiquement modifiés.
Elle n'est pas applicable aux semences.

ISO 24333:2009(E) iv © ISO 2009 – All rights reserved 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 24333 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 338, Cereal and cereal products, in collaboration with Technical Committee ISO/TC 34, Food products, Subcommittee SC 4, Cereals and pulses, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This first edition of ISO 24333 cancels and replaces ISO 6644:2002[5] and ISO 13690:1999[7]. SIST EN ISO 24333:2010
ISO 24333:2009(E) © ISO 2009 – All rights reserved v Introduction Sampling is a procedure which requires both a method and equipment that are suitable for the task. Any analysis of the characteristics of a lot and any interpretation of the results would prove futile if the sample were not representative of the lot from which it was taken. Sampling is a procedure which requires a great deal of care. It is strongly recommended that the task be entrusted to personnel who have been trained to use the appropriate equipment.
INTERNATIONAL STANDARD ISO 24333:2009(E) © ISO 2009 – All rights reserved 1 Cereals and cereal products — Sampling 1 Scope This International Standard specifies requirements for the dynamic or static sampling, by manual or mechanical means, of cereals and cereal products, for assessment of their quality and condition. It is applicable to sampling for the determination of heterogeneously distributed contaminants, undesirable substances, and parameters usually homogeneously distributed like those used to assess quality or compliance with specification. It can be used to determine insects in a grain lot. NOTE 1 Other methods, e.g. trapping whilst grain is in storage, are more suitable to assess pest populations. It is applicable to sampling for assessment of the quality and condition of lots of genetically modified organisms (GMO) but is inappropriate for the determination of the presence of adventitious genetically modified material in non-GM product. It is not applicable to seed grain. NOTE 2 The sampling of seed grain is governed by the rules established by the ISTA (International Seed Testing Association). NOTE 3 At the time of publication, there is no study to support the inclusion of the sampling of non-GM product in order to determine adventitious GM presence within the scope of this International Standard. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 lot 〈cereals〉 identified quantity of material (cereal or cereal product) from which a sample can be taken and controlled to determine one (or several) characteristic(s) 2.2 sampling act of drawing or constituting a sample [ISO 3534-2:2006[3], 1.3.1] 2.3 increment 〈cereals〉 amount of material taken at one time at each individual sampling point throughout a lot NOTE Adapted from ISO 3534-2:2006[3], 5.2.7. SIST EN ISO 24333:2010
ISO 24333:2009(E) 2 © ISO 2009 – All rights reserved 2.4 aggregate sample composite sample 〈cereals〉 aggregation of two or more increments (2.3), taken by experimental sampling (2.2) throughout a lot (2.1), combined and homogenized NOTE Adapted from ISO 3534-2:2006[3], 5.3.4. 2.5 laboratory sample 〈cereals〉 sample prepared by homogenizing and dividing an aggregate sample (2.4) for sending to the laboratory and intended for inspection or testing NOTE Adapted from ISO 6206:1979[4], 3.2.10. 2.6 homogenization thorough blending by mechanical or manual means so that contaminants and physical properties are evenly distributed throughout the aggregate or laboratory sample 2.7 packed unit quantity of grain or milled product packed in a sack, a bag or a retail pack 2.8 sampling error 〈cereals〉 that part of total estimation of error of a characteristic due to the heterogeneity of the characteristics, the nature of sampling and to known and acceptable deficiencies in the sampling plan NOTE Adapted from ISO 7002:1986[6], A.42. 3 General requirements 3.1 In this International Standard, sampling includes the following stages: a) taking a defined number of increments to constitute an aggregate sample; b) homogenization of the aggregate sample; c) reduction of the aggregate sample into laboratory sample(s). 3.2 Since the composition of the lots of cereals is rarely homogeneous and since certain contaminants are distributed in a non-uniform way, a sufficient number of increments shall be taken and carefully mixed to constitute an aggregate sample from which it will subsequently be possible to obtain one or several laboratory sample(s). For non-flowing commodities (static), particular care shall be taken to ensure that these increments are distributed regularly throughout the grain mass, both at the surface and deep down. 3.3 Precautions shall
