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

22、f this document. 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 o

23、f this type C standard. 1 Scope This standard specifies the essential safety requirements applicable to the design and construction of shredders used for plastic and rubber. The machine begins with the outer edge of the feed hopper and ends with the discharge area. This standard does not deal with e

24、quipment for feeding material or discharging shredded material. This standard does not deal with safety measures to reduce the risk from ignition of flammable residues in material to be shredded This standard does not deal with requirements for local exhaust ventilation systems. Only the significant

25、 hazards listed in clause 4 and dealt with in clause 5 are subject to this standard. NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The p

26、resent standard does not necessarily comply with Directive 94/9/EC. Additional safety requirements in a future revision of this standard may be necessary to satisfy Directive 94/9/EC. This standard applies to machines which are manufactured after the date of approval of this standard by CEN. 2 Norma

These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references subsequent amendments to or revisions of a
