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 the definitions according to EN 15436-1:2008, 5.1 to 5.6. 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. SIST EN 15436-2:2015

FprEN 15436-2:2014 (E) 4 Foreword This document (FprEN 15436-2:2014) has been prepared by Technical Committee CEN/TC 337 “Road operation equipment and products”, the secretariat of which is held by AFNOR. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 15436-2:2008. Compared to the previous version, this new standard includes few editorial corrections, wording improvements and technical precisions (e.g. accuracy of some measurements) and a new Annex D dealing with the test protocol for the measurement of power at the tool. EN 15436, Road service area maintenance equipment, is composed with the following parts: — Part 1: Terminology; — Part 2: Performance assessment [the present document]; — Part 3: Classification [currently at UAP stage]; — Part 4: Delivery acceptance of the machines by the users. kSIST FprEN 15436-2:2015
FprEN 15436-2:2014 (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. kSIST FprEN 15436-2:2015
FprEN 15436-2:2014 (E) 6 1 Scope This document specifies the accuracy of the performance measurement system of road service area maintenance equipment described in the scope of CEN/TC 337 and used for: — grass-cutting and brush-cutting; — mechanical plant-cutting. 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 document does not cover the collection and transportation of shredded grass. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. 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 EN 15436-1:2008, 6.25. 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 EN 15436-1:2008, 6.26. 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). A distinction is made between the value of the stop times for open hydraulic circuits and for closed hydraulic circuits. kSIST FprEN 15436-2:2015

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 the definitions according to EN 15436-1:2008, 5.1 to 5.6. 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. kSIST FprEN 15436-2:2015
