BS EN 703:2004+A1:2009EN 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
23、events are covered are indicated in the scope of this document. These hazards are specific to machines for loading (including silage cutting), mixing and/or chopping and distributing silage. Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted a
24、nd trailed) are dealt with in EN 1553. When provisions of this type C standard are different from those which are stated 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 accordi
25、ng to the provisions of this type C standard. BS EN 703:2004+A1:2009EN 703:2004+A1:2009 (E) 5 1 Scope This document, used 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
26、have a combination of two or more of the following functions: loading, mixing, chopping and distributing silage and/or other 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 practice
27、s (including residual risks) to be provided by the manufacturer. This document applies only to machines that have the following functional combinations: mixing and distributing functions; or mixing, chopping and distributing functions; or loading, mixing and distributing functions; or loading, mixin
28、g, chopping and distributing functions; or chopping and distributing functions; or loading, chopping and distributing functions. 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 f
29、ield; to loading cranes; to silage buckets. NOTE 1 Loading cranes are dealt with in EN 12999. NOTE 2 Silage buckets will be 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, mixi
30、ng and/or chopping and distributing silage and/or other feedstuffs, when they are used as intended and under the conditions 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
31、of stopping the machine in the best possible conditions; travelling of machinery; break-up of parts rotating at high speed. 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 oth
32、er feedstuffs which are manufactured before the date of publication of this document by CEN.
