4、requirements” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section Htten- und Walzwerkeinrichtungen. This standard concretizes the basic requirements set out in Annex I of the E
5、U Machinery Directive (Directive 98/37/EC) and the new EU Machinery Directive 2006/42/EC which becomes applicable on 29thDecem-ber 2009, relating to machinery and equipment for continuous casting of steel to be placed on the EEA market, with the intent of simplifying the means of proving conformity
6、with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Union, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called “presumption of conformity”).

27、ication of an identical text or by endorsement, at the latest by June 2008, and conflicting national standards shall be withdrawn at the latest by June 2008. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports
28、essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA and ZB which are an integral part of this document.

The machines and equipment concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. When provisio
31、n of this type C standard is 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. DIN EN 1
32、4753:2008-03 EN 14753:2007 (E) 6 1 Scope This European Standard applies for plant (containing machinery and equipment) used in the process of continuous casting of liquid steel (hereafter referred to as continuous casting machine, CCM) as defined in 3.1 and illustrated in Annex B. This European Stan
33、dard deals with all significant hazards, hazardous situations and events relevant to machinery and equipment for the continuous casting of steel, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard
34、specifies the safety requirements to be met during design, assembly, transport, commissioning, operation, maintenance (as described in Clause 5) and decommissioning of the equipment. This European Standard assumes that the machinery and equipment of the plant is operated and maintained by adequately
35、 trained and competent personnel (see 7.4). Manual intervention for setting, adjustment and maintenance is accepted as part of the intended use of the plant. This European Standard assumes that the machinery is used with adequate workplace lighting conforming to EN 12464-1. NOTE Local regulations re
36、garding lighting should be considered and could differ from requirements of EN 12464-1. This European Standard applies to: CCM for the transformation of molten liquid steel into solid products in sections (e.g. square, rectangular, beam blank, circular) from the point where overhead cranes or other
37、transport systems deposit ladles (e.g. in a ladle turret or ladle car); via casting process; via cutting equipment; to the run-out-area where the cut product is collected. This European Standard does not cover safety requirements for: auxiliary plants (e.g. water treatment, refractory handling); lad
38、les; cranes; winches and hoists; conveyors or handling systems. This European Standard is not applicable to CCM, manufactured before the date of publication of this standard by CEN.
