25、034-8:2012 (E) 6 1 Scope This European Standard applies to low consistency refining plants, i.e. plants working with suspensions of fibres of virgin pulp, mechanical wood pulp or deinking pulp in water with a consistency up to approximately 6 %, used in the paper making process and applies together

26、with EN 1034-1:2000+A1:2010. It deals with all significant hazards, hazardous situations and hazard events relevant to refining plants, when used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This standard does not apply to beaters. This document is not applicable

27、 to machines which are manufactured before the date of publication of this document by CEN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
