Bibliography

1.1This document applies for machinery and plant 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;c)waste 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.1.2This 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.1.3This document is not applicable to machinery and plant which are manufactured before the date of publication of this document by CEN.
