4、afety requirements. This standard has been prepared by Technical Committee CEN/TC 144 “Tractors and machinery for agriculture and forestry” (Secretariat: AFNOR, France), Working Group WG 3 “Mobile machines and trailers”. The responsible German body involved in its preparation was the Normenausschuss
5、 Maschinenbau (Mechanical Engineering Standards Committee), Section Landtechnik. Amendment of the European Machinery Directive has made it necessary to review the previously valid standard, EN 703:2004, in terms of the essential requirements of the new European Machinery Directive, 2006/42/EC. This
6、standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC, (valid until 28 December 2009) and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to silage loadi
7、ng, mixing and/or chopping and distributing machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the Europea
8、n Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in clause 2 of this document have been published as the corresponding
9、 DIN EN or DIN EN ISO Standards with the same number. This standard makes reference to documents which were valid as of the publication of the European standard. Since then, the standards EN 294:1992, EN 1070:1998 and EN 1553:1999 have been withdrawn. EN 294:1992 has been superseded by EN ISO 13857:
10、2008, EN 1070:1998 has been superseded by EN ISO 12100-1:2003 and EN ISO 12100-1:2003/A1:2009 and EN 1553:1999 has been superseded by EN ISO 4254-1:2005. 2 DIN EN 703:2009-12 Amendments This standard differs from DIN EN 703:2005-02 as follows: a) In subclause 5.6.1.2, the heading and the first parag
11、raph have been modified. b) In subclause 5.7.2, Figures 5, 6 and 7 have been modified. c) The information to be given in the instruction handbook has been modified (7.1). d) The marking of the machinery has been modified (7.2). e) Annex ZA (informative) “Relationship between this European Standard a

30、 EN 703:2004+A1:2009 (E) 4 0 Introduction This document is a type C standard as stated in EN 1070. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. These hazards are specific to machines for loading (inc
31、luding silage cutting), mixing and/or chopping and distributing silage. Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted and trailed) are dealt with in EN 1553. When provisions of this type C standard are different from those which are state
32、d in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. DIN EN 703:2009-12 EN 703:2004+A1:2009 (E) 5 1 Scope This document, used
33、together with EN 1553, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted, trailed or self-propelled machines that have a combination of two or more of the following functions: loading, mixing, chopping and distributing silage and/or oth
34、er feedstuffs, to be used by one operator only. It includes those fitted with a built-in loading crane. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. This document applies only to machines that have the foll
35、owing functional combinations: mixing and distributing functions; or mixing, chopping and distributing functions; or loading, mixing and distributing functions; or loading, mixing, chopping and distributing functions; or chopping and distributing functions; or loading, chopping and distributing func
36、tions. Silage block cutters, even if they carry out a single function, are covered by this document. It does not apply: to machines which pick up green fodder directly from the field; to loading cranes; to silage buckets. NOTE 1 Loading cranes are dealt with in EN 12999. NOTE 2 Silage buckets will b
37、e dealt through an amendment or during next revision. This document deals with all the significant hazards, hazardous situations and events relevant to machines for loading, mixing and/or chopping and distributing silage and/or other feedstuffs, when they are used as intended and under the condition
38、s foreseen by the manufacturer as listed in clause 4, except for the hazards arising from: failure of the control circuit; inadequate seating; inadequate lighting; impossibility of stopping the machine in the best possible conditions; travelling of machinery; break-up of parts rotating at high speed
39、. It is not applicable to environmental hazards (except noise). This document is not applicable to machines for loading, mixing and/or chopping and distributing silage and/or other feedstuffs which are manufactured before the date of publication of this document by CEN.
