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 events 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 designed 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 specifies 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 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 foreseen 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 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.
