3.1.3. Moisture content of the crop (see 10TCN 917-1: 2006, definition 3.1.6) shall be expressed on the wet basis. The percentage moisture of the grain shall be determined from samples taken from the grain flow into the grain tank, during the test runs. The MOG samples shall be taken from the deposited residue behind the combine, applicable to a test run just made. Both samples shall be sealed in air-tight containers.

3.1.4. Grain flow from the combine should be controlled, for each crop indicated,so as to give a processing loss level (see 10TCN 917-1: 2006, definition 4.2.2) during the operation specified in table 1. In addition, in regions where difficult conditions prevail and other percentage loss levels are appropriate, the conditions shall be defined.

3.2. Dimensions

Dimensions of combines shall be measured under specific conditions. The presence of equipment and additional components shall be noted.

3.2.1. Combine length (see 10TCN 917-1: 2006, definition 3.4.2) shall be measured, both in road travel condition and equipped for field operation. In the field conditions, the head shall be fully raised and the reel fully forward; the longest available divider shall be fitted. If other equipment, options or attachments affect the length, such equipment shall be specified.

3.2.2 Combine height (see 10TCN 917-1: 2006, definition 3.4.3) shall be measured withall components in position for transport. The height with all components in position for field operation shall be specified. It shall be stated whether or not the combine is fitted with a cab.

3.2.3 Combine width (see 10TCN 917-1: 2006, definition 3.4.4) shall be measured both in the road travel condition and equipped for field operation. In the field condition, the head fitted shall be the same as that fitted when determining head working width and effective cutterbar width as specified in 10TCN 917-1: 2006, definitions 3.5.1 and 3.5.2.

3.2.4 The turning diameter (see 10TCN 917-1: 2006, definition 3.4.6) shall be measured in accordance with TCVN 1773-3:1999, without applying the brakes.

3.2.5 The clearance diameter (see 10TCN 917-1: 2006, definition 3.4.7) shall be measured in accordance with TCVN 1773-3:1999

3.2.6 Where adjustable dividers are used, the minimum and maximum head working widths (see 10TCN 917-1: 2006, definition 3.5.1) shall be indicated.

3.2.7 Where the header width is adjustable, the minimum and maximum effective working widths of maize head cutters (see 10TCN 917-1: 2006, definition 3.5.3) shall be indicated, including the number of picking units.

3.2.8 The ground clearance, the maximum discharge height, the maximum clearance height, the maximum reach and the height of the cutterbar (see 10TCN 917-1: 2006, definitions 3.4.8, 3.4.9, 3.4.10, 3.4.11 and 3.5.6, respectively) shall be determined under thefollowing conditions:

a) Tyre and wheel or track equipment shall be stated, and tyres shall be inflated to the field operating pressures recommended by the combine manufacturer.

b) The plane on which the combine is standing shall be substantially level.

c) The size and type of head and reel installed at the time of measuring shall be stated.

d) All optional equipment mounted on the machine shall be specified.

Furthermore,the height of the cutterbar shall be stated as the highest point and the lowest point to which the cutterbar can be raised or lowered, measured from the ground plane to the tip of the knife section.

3.2.9 Single or multiple cylinders or rotors may be disposed laterally (see figure 1) or longitudinally (see figure 2) within the combine. If multiple cylinders or rotors are used, the number shall be stated and the dimensions given as in figures 1 and 2. If more than one concave is used, the dimensions and surfacesof each of them shall be indicated separately

3.2.10 The surface of auxiliaryseparating devices (see 10TCN 917-1: 2006, definition 3.2.1.6.5) shall not be added to that of separating devices.

3.2.11 If there are adjustable sections at the rear of the straw walker, they shall be fully extended when determining the length of the walkers (see 10TCN 917-1: 2006, definition 3.5.22).

3.2.12 Devices that only convey material within the combine (e.g.grain pans, augers, paddles and other non-permeable conveyors) while they can contribute to good separation by stratifying the material advantageously, do no actual separation of grain from MOG, and their areas may not be classified as separating areas, or added to the other separating areas (see 10TCN 917-1: 2006, definitions 3.5.14, 3.5.17, 3.5.20).

3.2.13 If the machine has more than one rotor, with its related concave and separating grates, this shall be indicated with the length and the area of the separating grate (see 10TCN 917-1: 2006, definitions 3.5.24 and 3.5.26, respectively). The concave grate surfaces are cumulative. This is also the case for separating grates.

3.2.15 Surfaces of dirt screens, recleaners, and other auxiliary cleaning devices. These areas shall be specified. Permeable surfaces and pneumatic cleaning areas shall be calculated and expressed in accordance with 10TCN 917-1: 2006, definitions 3.5.27 and 3.5.28, respectively.

3.2.16 For purposes of combine specification, the areas defined in 10TCN 917-1: 2006, definitions 3.5.9, 3.5.16, 3.5.17, 3.5.18, 3.5.23, 3.5.26 and 3.5.27 shall be listed individually and should not be used singly or in combination as a measure of machine performance or capacity.

3.3 Other characteristics

3.3.1 The enginenet power (see 10TCN 917-1: 2006, definition 3.4.5) shall be determined by appropriate method.
