Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 15436-2:2008 (E) 5 Introduction Road service area grass-cutting, brush-cutting and mechanical plant-cutting operations require special equipment that meets clearly defined technical criteria. This European Standard defines and describes the test methods used to monitor, assess and measure the technical performance of new equipment (head of series) in its working configuration with the production-run requirements tool. The accuracies indicated in this European Standard apply only to the measurements taken to assess the performance of the machines away from the plants. SIST EN 15436-2:2008

This equipment is mounted on self-propelled carrying vehicles and is designed to cut and shred grass, brushwood, trees, saplings and bushes in road service areas. This European Standard does not cover the collection and transportation of shredded grass. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 15436-1:2008, Road service area maintenance equipment — Part 1: Terminology 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 15436-1:2008 apply. 4 Cutting specifications check 4.1 Articulated-arm grass cutter – brushcutter 4.1.1 Cutting width (w) Cutting width is defined according to 6.25 of EN 15436-1:2008. It is measured with an accuracy of ± 0,01 m and expressed in metres (m). 4.1.2 Cutting height (h) Cutting height is defined according to 6.26 of EN 15436-1:2008. It is measured with an accuracy of ± 0,005 m and expressed in metres (m). In the case of continuous adjustment, the minimum and maximum heights should be measured. In the case of intermittent adjustment, the various possible heights allowed by the cutting tool should be measured. 4.1.3 Cutting rotor stop time The cutting rotor stop time is measured automatically, from the time the stop command is sent to the moment when the rotation speed is measured as being equal to 0. The cutting rotor stop time is measured with an accuracy of ± 0,1 s and expressed in seconds (s). SIST EN 15436-2:2008
EN 15436-2:2008 (E) 7 A distinction is made between the value of the stop times for open hydraulic circuits and for closed hydraulic circuits. 4.2 In-line flail mower 4.2.1 Cutting width (w) The cutting width is measured with an accuracy of ± 0,01 m and expressed in metres (m). 4.2.2 Cutting height (h) The cutting height is measured with an accuracy of ± 0,005 m and expressed in metres (m). In the case of continuous adjustment, the minimum and maximum heights should be measured. In the case of intermittent adjustment, the various possible heights allowed by the cutting tool should be measured. 4.2.3 Cutting tool stop time The cutting rotor stop time is measured automatically, from the time the stop command is sent to the moment when the rotation speed is measured as being equal to 0. The cutting rotor stop time is measured with an accuracy of ± 0,1 s and expressed in seconds (s). A distinction is made between the value of the stop times for open hydraulic circuits and for closed hydraulic circuits. 4.3 Mechanical plant cutting 4.3.1 Cutting width (w) The cutting width is measured with the engine off. The cutting width is the distance measured between the active ends of the fingers of the bars, with the cutters of the blades or saws in the furthest possible position (Figure 1). The cutting width is measured with an accuracy of ± 0,01 m and expressed in metres (m). SIST EN 15436-2:2008

Whatever the shape and size of the components and any accessories that may be used, there is always an articulation between the frame and the primary arm. The articulation which is very close to the frame is used to define three reference planes for the machine. The kinematic properties of the different machines are then defined with respect to these reference planes. See definitions according to 5.1 to 5.6 of EN 15436-1:2008. SIST EN 15436-2:2008
EN 15436-2:2008 (E) 9 Given that the height, in relation to the ground plane of the primary arm–frame articulation changes the geometry of certain operating positions significantly, the horizontal reference plane of the machine is positioned at a height ZP from the ground specified by the manufacturer. This height can vary. See definitions according to Clause 4 of EN 15436-1:2008. 5.2 Articulated-arm grass cutters - brushcutters 5.2.1 General The kinematic properties defining the operating positions are shown in the diagram in Figure 2. They are described in the subclauses below. Point X is defined at a distance of 1,10 m from the mid-plane. Dimension XP, defined in 4.2 of EN 15436-1:2008, is specified by the manufacturer with an accuracy of ± 0,01 m. Dimension ZP, defined in 4.4 of EN 15436-1:2008, is specified by the manufacturer with an accuracy of ± 0,02 m. Dimension YP, defined in 4.3 of EN 15436-1:2008, is specified by the manufacturer with an accuracy of ± 0,01 m.
