Foreword This European Standard (EN 1034-22:2005) has been prepared by Technical Committee CEN/TC 198 “Printing and paper machines - Safety”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 3005, and conflicting national standards shall be withdrawn at the latest by December 2005. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

Introduction This European Standard is a C type standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. For machines that have been designed and built according to the provisions of this C standard, the following stipulation applies: When provisions of this type C standard are different from those which are stated in type A or B standards or from provisions made in EN 1034-1:2000, the provisions of this type C standard take precedence over the provisions of the other standards. 1 Scope This European Standard applies to wood grinders intended for the production of pulp used in paper making including sharpening devices and shall be used together with EN 1034-1:2000. It deals with all significant hazards, hazardous situations and hazard events relevant to wood grinders when used as intended and under the conditions foreseen by the manufacturer (see clause 4). This standard does not apply to loading facilities. Hazards caused by overpressure are not covered by this standard. Note: For hazards caused by overpressure, see the directive for pressure vessels. This European Standard is not applicable to wood grinders 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.
