27、y 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of an identical text or by endorsement, at the latest by May 2008, and conflicting national standards shall be withdrawn at the latest by May 2008. This document has been prepared under a mandate gi
28、ven 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 and Annex ZB, which are an integral part of this document. According to the CEN/CENELEC Internal Regu
29、lations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Neth

EN 12151:2007 (E) 6 Introduction This document is a type C standard as stated in EN ISO 12100-1:2003. The machinery concerned and the extent to which hazards, hazardous situations and event
31、s are covered are indicated in the scope of 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 design
32、ed and built according to the provisions of this type C standard. The road traffic law for each country remains unaffected by this standard. EN 12151:2007 (E) 7 1 Scope 1.1 This document applies for machinery and plants for the preparation of concrete and mortar as defined in 3.1. This document spec
33、ifies the requirements for the design of: a) batching and mixing installations for concrete and mortar; b) powered mixers for concrete and mortar, including for storage and handling; c) waste fresh concrete reprocessing plant. It does not include requirements relevant to truck mixers. The machinery
34、may be static or it may be capable of being moved to an alternative position. 1.2 This document deals with all significant hazards, hazardous situations and events relevant to machinery and plant for the preparation of concrete and mortar, when they are used as intended and under the conditions fore
35、seen by the manufacturer (see Clause 4). The exceptions are explosion hazards when using flammable or explosive materials that are significant but not dealt with. This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. Maintenance
36、 is dealt with but not noise during maintenance. 1.3 This document is not applicable to machinery and plants which are manufactured before the date of publication of this document by CEN. 2 Normative references The following referenced documents are indispensable for the application of this document
