[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 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 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 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 normative references; addition of definitions; addition of 4.1.3,

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 13740-2:2003) If the term ‘machine’ is used it covers both full width distributors and broadcasters, except in the case of definitions in Part 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 Normative references The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated
