21、BS EN 15436-2:2015EN 15436-2:2015 (E) 4 Foreword This document (EN 15436-2:2015) has been prepared by Technical Committee CEN/TC 337 “Road operation equipment and products”, the secretariat of which is held by AFNOR. This document supersedes EN 15436-2:2008. This European Standard shall be given the

22、 status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2016, and conflicting national standards shall be withdrawn at the latest by January 2016. Attention is drawn to the possibility that some of the elements of this document may be th

23、e subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. 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

24、 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; Part 4: Delivery acceptance

25、 of the machines by the users. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Rep

26、ublic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 15436-2:2015EN 15436-2:2015 (E) 5 Introduction Roa

27、d 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 (h

28、ead 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. BS EN 15436-2:2015EN 15436-2:2015 (E) 6 1 Scope This European

29、 Standard 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 designe

30、d 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 documents, in whole or in part, are normatively referenced in this document and are i

31、ndispensable 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.

32、 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 exp

33、ressed 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 a

34、djustment, 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

35、 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.

The cutting

38、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 eng

39、ine 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). BS EN 15436-2:2015EN 1543

A distinction is made between the value of the stop times for open hydraulic circuits and for closed hydraulic circuits. 5 Kinematic properties check 5.1 General In their design structure, al

42、l these machines have the same constituent elements, i.e. a frame, articulated arms and a tool. 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

43、 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 a

44、rmframe 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. BS EN 15436-2:2015EN 15436-2:2015 (E) 9 See the definitions accordin

They are described in the subclauses below. Point X is defined at a distance of 1,10 m from the mid-plane.

46、 Dimension XP, defined in EN 15436-1:2008, 4.2 is specified by the manufacturer with an accuracy of 0,01 m. Dimension ZP, defined in EN 15436-1:2008, 4.4 is specified by the manufacturer with an accuracy of 0,02 m. Dimension YP, defined in EN 15436-1:2008, 4.3 is specified by the manufacturer with a

48、nkment range (E) Embankment range is defined in EN 15436-1:2008, 6.22. The measurement system accuracy of the embankment range E is 0,02 m. The embankment range E is measured on the 45 inclined plane on which the cutting head rests. The inclined plane is positioned at X on the ground plane. The angl

49、e of 45 is measured with an inclinometer and the measurement system accuracy of the inclination is 1. The inclined plane allows the range E to be measured directly. 5.2.4 Ditch range (D1) Ditch range is defined in EN 15436-1:2008, 6.23. The measurement system accuracy of the ditch range D1is 0,02 m. The ditch range D1can be measured on the 45 inclined plane on which the cutting head rests. The inclined plane is positioned at X with respect to the ground plane. The angle of 45 is measured with an inclinometer and
