8、Standard has been prepared by Technical Committee AW/2 and is the English language version of EN ISO 664:1995 Oilseeds Reduction of laboratory sample to test sample, published by the European Committee for Standardization (CEN). It is identical with ISO 664:1990 published by the International Organi
9、zation for Standardization (ISO) and in the preparation of which the UK played a full part. It supersedes BS 4289-1:1990 which is withdrawn and from which it differs in that the cross-references have been updated. A British Standard does not purport to include all the necessary provisions of a contr
10、act. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

22、993 1 Scope This International Standard specifies the procedure for obtaining a test sample from a laboratory sample of oilseeds. NOTE 1Some 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
23、 for the preliminary quantitative separation of impurities and analysis of the pure seed separated. Analysis of the impurities may also be required. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Sta
24、ndard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC
25、and ISO maintain registers of currently valid International Standards. ISO 658:1988, Oilseeds Determination of impurities content. 3 Principle After the separation of impurities of large size, if necessary, division of the laboratory sample by appropriate means to obtain a test sample representative
26、 of the laboratory sample. 4 Apparatus 4.1 Dividing apparatus, e.g. quartering apparatus, conical divider, multiple-slot divider with distribution system, or other dividing and sorting apparatus which will ensure uniform distribution of the components of the laboratory sample in the test sample. 4.2
27、 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 of the seals and the container. Store the laboratory sample in a secure place away from heat and e
28、xtremes of humidity until the test sample is to be prepared. 5.2 Open the laboratory sample carefully and, without delay, carry out the following procedure. First, weigh the laboratory sample and, if necessary, separate and weigh impurities of large size, i.e. those that cannot be mixed in to provid
29、e 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 the seed, reduce it successively until the minimum mass specified in Table 1 has been obtained. For seeds not included in Tabl
30、e 1, the minimum mass of seeds to be obtained shall be the same as that prescribed for species of similar size. If separation of impurities is required, follow the procedure specified in ISO 658. 5.3 Place the resulting test sample in a dry, clean, container (4.2), close it hermetically and label it
31、. 6 Storage of the test sample Store the test sample in a secure place away from heat and extremes of humidity. The analyses shall be carried out as soon as possible after the preparation of the test sample and, in all cases, within 48 h. Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 13:57:
