    10、bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental

    11、and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives

    12、, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies cas

    13、ting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 17101-2 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agri

    14、culture and forestry, Subcommittee SC 7, Equipment for harvesting and conservation.This first edition of ISO 17101-2, together with ISO 17101-1, cancels and replaces ISO 17101:2004, which has been technically revised.ISO 17101 consists of the following parts, under the general title Agricultural mac

    16、 gives specifications and acceptance criteria for the thrown-object testing of flail mowers used in agriculture. Examples of machines are shown in Annex A. It is not applicable to the following: large rotary mowers; rotary mowers; mowers with an articulated arm; mowers with one or more vertical axis

    17、 designed for mulching; pedestrian controlled motor mowers; lawn mowers or machines designed as lawn mowers; inter-row mowing units; machines designed for highway and road maintenance only; flail mowers that have the rear part which can be opened for particular field use operations (e.g. row-crop mo

    18、wers).NOTE 1 If a machine is also designed for use outside agriculture, in addition to the thrown-object test given in this part of ISO 17101, other thrown object tests might apply.NOTE 2 Thrown-object tests and acceptance criteria for rotary mowers are dealt with in ISO 17101-1.2 Normative referenc

If the flail mower can be operated in different working positions (right side, centre or left side of the tractor, see 4.2.7),

    27、the test shall be performed with the flail mower in the rightmost and leftmost working positions behind the tractor as specified by the manufacturer in the operators manual.2 ISO 2012 All rights reservedBS ISO 17101-2:2012ISO 17101-2:2012(E)4.1.1.1 Thrown-object guard adjustmentAdjustable devices, w

If this is not possible due to the design of the flail mower, the cutting height shall be adjusted

    29、 as near as possible to 50 mm.4.1.2 Test surface area4.1.2.1 Ground conditionsTests shall be performed on firm and horizontal, hard ground.EXAMPLES Concrete, asphalt.4.1.2.2 Coconut mattingThe test surface area shall be lined with coconut matting with fibres measuring approximately 20 mm in height,

There shall be no overlapping of Kraft paper, and, in order to have no overlaps, the Kraft paper should be stretched from the roll in the horizontal direction on the frames.In order

    35、to have no overlaps per panel, it is recommended that the Kraft paper from the roll be stretched in a horizontal direction.

    36、ess of the top supporting slat (see Figures 2 to 6).4.2.1.4 Panel reference linesThree horizontal reference lines, traced along the target at 200 mm, 600 mm and 2 000 mm from the ground level, shall show three zones: a lower zone (between 0 mm and 200 mm); a middle zone (between 200 mm and 600 mm);

    37、and an upper zone (between 600 mm and 2 000 mm) (see Figure 1).If the flail-mower configuration requires the panels shown in Figures 5 to 11 to be moved further from the flail mower, the reference lines shall be moved proportionally upwards see Figure 2 a).The horizontal reference lines of Panel 6,

    38、which is used for front-mounted flail mowers see Figure 2 b), shall be located 500 mm and 1 000 mm from the ground level and show three zones: a lower zone (between 200 mm and 500 mm); a middle zone (between 500 mm and 1 000 mm); and an upper zone (between 1 000 mm and 1 200 mm). If Panel 6 needs to

    39、 be moved towards the rear due to the flail-mower dimensions, reference lines shall be moved proportionally upwards. see Figure 2 c).Panels 1 to 4 shall be divided into vertical sections 1 000 mm wide, starting from one of the edges of the enclosure formed by the target panels. Panel 6, if present,

    40、shall also be divided into vertical sections 1 000 mm wide, starting from one of its edges. The sections shall be numbered.4 ISO 2012 All rights reservedBS ISO 17101-2:2012ISO 17101-2:2012(E)Dimensions in millimetres445555L3L3L2L2L1L152223314366Z1Z1Z2Z2Z3Z3202002006006002 0002 000KeyL1 200 mm refere
