Emphasis cannot therefore be too strongly laid on th
20、e necessity of obtaining a properly representative sample of milled cereal or pulse. Careless or inaccurate sampling could lead to misunderstanding and unwarranted financial adjustment. The procedures given in this International Standard are recognized as good practice and it is strongly recommended
21、 that they be followed whenever practicable. It is recognized that it is difficult to lay down fixed rules to be followed in every case, and particular circumstances may render some modification of the method desirable, for example if it is desired to check the uniformity of a consignment by the exa
22、mination of individual increments. In certain areas there are widely recognized trade associations which prescribe rules for the sampling procedures to be used in contracts under their auspices. In no case will the methods described in this International Standard override the rules laid down in such
23、 contracts, or the rules of official inspecting organizations. 1 Scope and field of application This International Standard specifies general conditions relating to the sampling for assessment of quality and condition of milled products from cereals and pulses, intended for human or animal consumpti

It does not apply to whole unprocessed cereal grains or pulses, to seed grains or pulses, or to partially milled cereals or pulses which retain the form of the original material1).
