23、azardous situations and events are covered are indicated in the scope 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 standar
24、ds, for machines that have been designed and built according to the provisions of this type C standard. BS EN 474-7:2006+A1:2009EN 474-7:2006+A1:2009 (E) 6 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to wheel and crawler scrapers except to
25、wed scrapers as defined in EN ISO 6165:2006, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). The requirements of this part are complementary to the common requirements formulated in !EN 474-1:2006+A1:2009“. This part
26、does not repeat the requirements from !EN 474-1:2006+A1:2009“, but adds or replaces the requirements for application for scrapers. This part specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards, hazardous situations and events during commissi
27、oning, operation and maintenance of scrapers. This European Standard is not applicable to scrapers manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
