The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scop

22、e of this European Standard. 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

23、provisions of this type C standard. EN 474-8:2006+A1:2009 (E) 5 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to graders as defined in EN ISO 6165:2006, when they are used as intended and under conditions of misuse which are reasonably fores

24、eeable by the manufacturer (see Clause 4). This part also deals with graders equipped with attached snowplough. 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“, b

25、ut adds or replaces the requirements for application for graders. This part specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards, hazardous situations and events during commissioning, operation and maintenance of graders. This European Standa

26、rd is not applicable to graders manufactured before the date of publication of this European Standard by CEN. NOTE When graders are intended for use in winter service, see EN 13021:2003 “Winter service machines Safety requirements” 2 Normative references The following referenced documents are indisp
