This European Standard shall be given the status of a national stand

26、ard, 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of an identical text or by endorsement, at the latest by April 2012, and conflicting national standards shall be withdrawn at the latest by April 2012.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 that some of the elements of this document may be the subject of patent rights. CEN

27、 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 machinery Solid fertilizer broadcasters and full width distributors Environmental

28、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 original document has been completed in order to describe how to test a spreader with

29、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 manufacturers have shown that the results obtained with conventional facility are s

30、trictly 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 normative references; addition of definitions; addition of 4.1.3, 5.3, 6.6.1.2, 6.6.2.2

31、 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, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Franc

CEN takes no position concerning the evidence, validity and scope of this patent right. Th

34、e 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 of the holder of this patent right is registered with CEN. Information may be obtai

DIN EN 13739-2:2012-05 EN 13739-2:2011 (E) 6 1 Scope This European Standard specifies methods to test mounted, trailed and self-propelled broadcasters and full width solid fertilizer distributors used in agriculture and horticulture. This European Standard does not apply to machi

37、nes 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 13740-2:2003). If the term machine is used it covers both full width distributors and broadcasters, excep

38、t 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 adapted to centrifugal spreaders. 2 Normative references The following referenced documents are i

39、ndispensable for the application of this document. For dated references, only the edition cited applies.
