For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the lates edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 71 2:1 998, Cereal and cereal products — Determination of moisture content — Routine reference method. ISO 7970:— 1 ) , Wheat (Triticum aestivum L.) — Specification . ISO 7971 -2:1 995, Cereals — Determination of bulk density, called “mass per hectolitre” — Part 2: Routine method . 3 Test method 3.1 Test preparations 3.1.1 During the test the combine harvester shall be stationary, placed horizontally on a level surface and running at rated speeds. The unloading device shall be engaged at rated speed with the feed table and threshing mechanisms previously engaged. 3.1.2 The wheat used for testing shall have a moisture content not exceeding 20 % measured in accordance with ISO 71 2, and a maximum impurity level of 3 %, measured in accordance with ISO 7970. A sample of the test wheat shall be taken and the wet basis moisture content, in percent, and the impurity content, in percent by mass, shall be determined and recorded. Also determine the mass per litre of the test wheat measured in accordance with ISO 7971 -2. 3.1.3 To ensure that the grain tank and unloading system are effectively empty before starting the rating tests, operate the grain unloading mechanism until the main unloading stream of grain has stopped and then continue to run the unloading system for at least one more minute before stopping.3.2 Test procedure 3.2.1 Fill the grain tank with the test wheat by means of its own loading system up to, but not beyond, the point of spillage. 3.2.2 Commence unloading the test wheat from the combine harvester grain tank using...
