EN 474-7:2006 (E) 4 Introduction This part of EN 474 is a type C standard as stated in EN ISO 12100-1:2003. The machinery concerned and
20、the extent to which hazards, hazardous 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 p
21、rovisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. EN 474-7:2006 (E) 5 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to wheel and crawler scrapers except towe
22、d 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. This part does not rep
23、eat the requirements from EN 474-1:2006, 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 commissioning, operation and m
24、aintenance 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.
