31、 Committee CEN/TC 202 “Foundry machinery”, the secretariat of which is held by 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 October 2009, and conflicting national standards shall be withdr
32、awn at the latest by December 2009. This document includes Amendment 1, approved by CEN on 2009-03-01. This document supersedes !EN 869:2006“. The start and finish of text introduced or altered by amendment is indicated in the text by tags ! “. This document has been prepared under a mandate given t
33、o 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 Annexes ZA and ZB, which are integral parts of this document.“ An assessment of the foreseeable risks arising from
34、 the use of the machinery was carried out when this standard was drafted by CEN/TC 202/WG 1, comprising experts from the following countries: Germany, Italy, Spain, Sweden and Switzerland. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countr
35、ies 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, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain
36、, Sweden, Switzerland and United Kingdom. BS EN 869:2006+A1:2009EN 869:2006+A1:2009 (E) 6 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the sco
37、pe 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 provisio
38、ns of this type C standard. !Where for clarity an example of a preventative measure is given in the text, this should not be considered as the only possible solution. Other solutions can be used as far as they fulfil correctly the criteria expressed in the requirement. This European Standard assumes
39、, that the equipment is operated and maintained by trained personnel.“ 1 Scope This European Standard specifies the safety requirements for pressure metal diecasting units. It applies to pressure diecasting machines and to the interfaces with the following ancillary equipment: die, melting, holding
40、and dosing furnaces (see EN 746-1), metal feeding equipment, inserting and removal devices, spraying appliances, heat exchanger for the die. This ancillary equipment itself is not covered. Additional risks arising from the material being cast are not covered. This standard does not apply to low pres
41、sure diecasting machines and/or gravity diecasting machines. This standard deals with all significant hazards, hazardous situations and events relevant to pressure diecasting machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Claus
42、e 4). It provides the requirements to be met by the manufacturer to ensure the safety of persons and property during transport, commissioning, use, de-commissioning and maintenance periods, as well as in the event of foreseeable failures or malfunctions that can occur in the equipment. This document
43、 is not applicable to pressure metal diecasting units/machinery which are manufactured before the date of its publication as EN.
