19、deration 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 com
20、mittee. 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 accord
21、ance 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 require
22、s 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.

26、e This International Standard specifies the procedure for obtaining a test sample from a laboratory sample of oilseeds. NOTE Some contracts for the trading of oilseeds call for analyses of the sample as drawn, i.e. including any impurities that may be present. However, some contracts call for the pr
27、eliminary quantitative separation of impurities and analysis of the pure seed separated. Analysis of the impurities can also be required. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited app
28、lies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 658, Oilseeds Determination of content of impurities 3 Principle After the separation of impurities of large size, if necessary, the laboratory sample is divided by appropriate means t
29、o obtain a test sample representative of the laboratory sample. 4 Apparatus Usual laboratory apparatus and in particular, the following. 4.1 Dividing apparatus, e.g. quartering apparatus, conical divider, multiple-slot divider with distribution system, or other dividing and sorting apparatus which w
30、ill ensure uniform distribution of the components of the laboratory sample in the test sample. 4.2 Sample container, that can be hermetically closed, of dimensions such that it can just accommodate the test sample. 5 Procedure 5.1 On receipt of the laboratory sample, check and record the conditions
31、of the seals and the container. Store the laboratory sample in a secure place away from heat and extremes of humidity until the test sample is to be prepared.

First, weigh the la
33、boratory sample and, if necessary, separate and weigh impurities of large size, i.e. those that cannot be mixed in to provide a homogeneous sample. Mix the remaining sample carefully in order to make it as uniform as possible and then, using a dividing apparatus (4.1) appropriate to the nature of th
34、e seed, reduce it successively until the minimum mass specified in Table 1 has been obtained. For seeds not included in Table 1, the minimum mass of seeds to be obtained shall be the same as that prescribed for species of similar size. If analysis of a sample free from impurities is required, follow
35、 the procedure specified in ISO 658. The separation of impurities before homogenization and division shall be taken into account in the expression of results. 5.3 Place the resulting test sample in a dry, clean, container (4.2), close it hermetically and label it. 6 Storage of the test sample Store
36、the test sample in a secure place away from heat and extremes of humidity. The analyses shall be carried out within time intervals compatible with the sample stability.
