25、held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2012, and conflicting national standards shall be withdrawn at the latest by April 2012. Attention is drawn to the possibility
26、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. This document supersedes EN 13739-2:2003. This standard consists of the following parts under the general title Agricultural
27、 machinery Solid fertilizer broadcasters and full width distributors Environmental protection: Part 1: Requirements; Part 2: Test methods. This document is a revision of EN 13739-2:2003 to take into account the fact that during last years a new concept of testing facility has been developed. The ori
28、ginal document has been completed in order to describe how to test a spreader with the new facility and how to calculate the results in order to make them comparable to the ones which would have been obtained with the conventional facilities. Comparative tests carried out in 2007 by test houses and
29、manufacturers have shown that the results obtained with conventional facility are strictly comparable to the ones obtained with new facility using the calculation methods of this document and allow verification. The following changes were introduced compared to the previous version: updating of norm
30、ative references; addition of definitions; addition of 4.1.3, 5.3, 6.6.1.2, 6.6.2.2 and 7.1.1.2 related to the “Rotating test“. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, B

CEN take
33、s no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has assured CEN that he is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement o
34、f the holder of this patent right is registered with CEN. Information may be obtained from: Vronique Vissac-Charles Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those identified above.

36、istributors used in agriculture and horticulture. This European Standard does not apply to machines which are: combined grain and fertilizer drills; or equipment for distributing granulated pesticides; or solid fertilizer line-distributors (which are dealt with in EN 13740-1:2003 and in EN 13740-2:2
37、003). If the term machine is used it covers both full width distributors and broadcasters, except in the case of definitions in Part 1. Two different methods are described in this European Standard to carry out the evaluation test: a transverse test and a rotating test. The rotating test is mainly a
38、dapted to centrifugal spreaders. 2 Normative references The following referenced documents are indispensable for the application of this document.

47、 the range of (4 0,4) km/h. The number of runs for each measurement shall be two. The flow adjustment using 4 km/h shall be set to correspond to the flow rate obtained at a forward driving speed of 10 km/h. If the machine is not designed to be used at a forward speed of 4 km/h, the forward test spee
48、d shall be within the range of (8 0,4) km/h or (10 0,5) km/h or (12 0,6) km/h and the number of runs shall be four resp. five resp. 6 with the flow rate set according to the forward speed. The test speed shall also in this case not vary by more than 0,1 km/h from run to run within each test. The forward speed, PTO ratio and disc speed shall be stated in the test report. The distributing mechanism shall be at the height above the fertilizer-collecting containers (the upper edge of the containers) equ
