1、 ASABE/ISO 17101-2:2012 JUN2016 Agricultural machinery Thrown-object test and acceptance criteria Part 2: Flail mowers American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are dedicated to advancement of engineering a
2、pplicable to agricultural, food, and biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally agricultural field equipment, farmstead e
3、quipment, structures, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Practices, and Data are informational and advi
4、sory only. Their use by anyone engaged in industry or trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with applicable ordinances, laws and regulatio
5、ns. Prospective users are responsible for protecting themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, regardless of the revision approval date. Newl
6、y developed Standards, Engineering Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard requires verification by ANSI that the re
7、quirements for due process, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much
8、more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at any time. Additionally, procedures of ASABE
9、 require that action be taken periodically to reaffirm, revise, or withdraw each standard. Copyright American Society of Agricultural and Biological Engineers. All rights reserved.

31、all be located in the least favourable position. 4.1.1.2 Cutting height The cutting height shall be adjusted at 50 mm. If this is not possible due to the design of the flail mower, the cutting height shall be adjusted as near as possible to 50 mm. 4.1.2 Test surface area 4.1.2.1 Ground conditions Te
32、sts shall be performed on firm and horizontal, hard ground. EXAMPLES Concrete, asphalt. 4.1.2.2 Coconut matting The test surface area shall be lined with coconut matting with fibres measuring approximately 20 mm in height, embedded in a support material. The determination of compression behaviour sh
33、all be carried out in compliance with ISO 3416. 4.1.2.3 Sand layer (natural, crushed or uncrushed) The coconut matting shall be covered with a layer of sand and shall be distributed in such a way as to leave visible the top of the coconut matting fibres. This condition shall be restored after each r

35、all be constructed of a rigid frame. The dimensions of Panels 1 to 4 are shown in Figure 1; the dimensions of Panels 5 and 7 are shown in Figure 3; and the dimensions of Panel 6 are shown in Figure 2 a). The Kraft paper shall be of 120 g/m2 10 g/m2construction, determined in accordance with ISO 536.
36、 The bursting strength shall be 500 kPa minimum, determined by using the method specified in ISO 2758. The tearing resistance shall be 1 200 mN minimum, in the machine direction, determined in accordance with the test method specified in ISO 1974. 4.2.1.2 Target material attachment There shall be no

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. ASABE/ISO 17101-2:2012 Copyright American Society of Agricultural and Bio
38、logical Engineers 5 In order to have no overlaps per panel, it is recommended that the Kraft paper from the roll be stretched in a horizontal direction. 4.2.1.3 Target panels frame Panels 1 to 4 shall be made of a rigid frame, 2 000 mm in height, plus the thickness of the top supporting slat (see Fi

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, which is used for front-mounted fl
41、ail 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 be moved towards the rear due to
42、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, shall also be divided into vertic
