The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard.
23、 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 according to the provisions of this type C st
24、andard. ? EN 474-9:2006+A1:2009 (E) 6 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to pipelayers as defined in EN ISO 6165:2006, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufactu
25、rer (see Clause 4). The requirements of this part are complementary to the common requirements formulated in !EN 474-1:2006+A1:2009“. This part does not repeat the requirements from !EN 474-1:2006+A1:2009“, but adds or replaces the requirements for application for pipelayers. This part specifies the
26、 appropriate technical measures to eliminate or reduce risks arising from the significant hazards, hazardous situations and events during commissioning, operation and maintenance of pipelayers. This part specifies additional requirements for rear mounted winches. Pipelayers with rotating upper struc
27、ture are excluded from the scope of this document. However, specific requirements are under development. This European Standard is not applicable to pipelayers manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are
