15、rs; it applies to all types of combine harvesters. The test procedure specified in this International Standard deals with the measurement and testing of combine harvesters, either of self-propelled or trailed type, either directly cutting the crop or picking it up from a wind-row, for use in several
16、 crops. It indicates terminology and methods to be used for measuring important characteristics of combines. It includes both functional and capacity tests, i.e.those conducted over an extended period when ease of operation, ease of adjustment, rate of work and general operating characteristics may
17、be assessed, and those carried out on specific occasions for the determination of grain loss and capacity characteristics. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.

28、ed or obtained for testing, and the approximate duration of any running prior to test shall be stated in the test report. 4.2 The combine shall normally be operated in accordance with the manufacturers instructions. The test report shall record and give reasons for any significant departure from the
29、m. 4.3 Commercially available accessories, as necessary or desirable for the various crops in which the combine is to be used, shall be provided. 4.4 Setting and adjustments of the machine shall be generally in accordance with the manufacturers instruction manual: the actual settings shall be record
30、ed and reported. 5 Characteristics of machine 5.1 Significant details All significant details of the combine shall be established and verified in accordance with the definitions, characteristics and performance criteria laid down in ISO6689. The terminology given in ISO5702 and ISO6689 shall be used
31、. 5.2 Speeds For self-propelled machines, measurements of the speed of any component shall be made under “no-load” conditions with the governor control lever set in the normal working position corresponding to the required working machine regime. For PTO (power take-off) driven machines, these speed
32、s shall be measured at standard PTO rotational frequency (540min 1 10min 1or1000min 1 25min 1 ) (see ISO500). Ground speeds shall be measured on a hard horizontal surface (see ISO3965), with the governor control lever in the normal working position and the crop processing mechanism disengaged. If th
33、e machine is fitted with stepless speed change mechanism, the maximum and minimum speeds obtained for each gear shall be measured. Otherwise, speeds obtained for all combinations of the gears shall be measured. 5.3 Position of centre of gravity It should be specified, for the machine tested, whether
34、 it is equipped with powered rear-wheel drive or not and if it has a chopper attachment. NOTEThis is a supplementary measurement applicable to self-propelled machines only. The position of the centre of gravity shall be determined under the following conditions (seeISO789-6): 5.4 Grain tank The grai
35、n tank capacity and unloading time shall be measured in accordance with ISO5687. 6 Functional field tests Functional field tests shall be carried out over an extended period, e.g.several months or a complete harvesting season in a particular area, and should include as wide a range as practicable of
36、 crops, crop varieties and/or crop conditions which are important to that area. 6.1 Information to be recorded In each field worked, the following information shall be recorded: a) atmospheric conditions; b) slope and state of ground; c) shape of field; d) height of stubble; e) crop: variety, condit
