4、Document comprises 16 pages04.10 DIN EN 474-7:2010-04 2 Start of validity This standard takes effect on 1 April 2010. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 151 “Construction equipment building material machines Saf
5、ety” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-13-01 AA Erdbau-/Straenbau-maschinen of Section Bau- und Baustoffmaschinen. Representatives of manufac
6、turers and users of earth-moving machinery, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC, (valid until 28 December 2009)
7、 and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the d
8、irectives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards refe
9、rred to in clause 2 and in the bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standards referred to in this standard there are no national standards available unless they have been published as DIN ISO standa
10、rds with the same number. Amendments This standard differs from DIN EN 474-7:2007-09 as follows: a) The foreword has been revised. b) Normative references in clause 2, subclauses 5.2, 5.6.1 and 5.6.2 have been revised. c) Annex ZB “Relationship between this European Standard and the Essential Requir
11、ements of EU Directive 2006/42/EC” has been included.

28、tandard as stated in EN ISO 12100-1:2003. The machinery concerned and 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 standa
29、rds, 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 standard. DIN EN 474-7:2010-04 EN 474-7:2006+A1:2009 (E) 6 1 Scope This part of EN 474 deals with all sign
30、ificant hazards, hazardous situations and events relevant to wheel and crawler scrapers except towed 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 pa
31、rt 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 scrapers. This part specifies the appropriate technical measures to eliminate or r
32、educe risks arising from the significant hazards, hazardous situations and events during commissioning, 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
33、 following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies.
