4、mmittee CEN/TC 202 “Foundry machinery” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section Gieereimaschinen. Attention is drawn to the possibility that some of the elements of
5、this document may be the subject of patent rights. DIN shall not be held responsible for identifying any or all such patent rights. Amendment of the European Machinery Directive has made it necessary to review the previously valid standard, EN 869:2006, in terms of the essential requirements of the
6、new European Machinery Directive, 2006/42/EC. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC, (valid until 28 December 2009) and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect o
7、n 29 December 2009, and which apply to foundry machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the Euro
8、pean Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in clause 2 and in the bibliography of the EN have been published
9、as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standards referred to in this standard there are no national standards available, except for those below, which correspond as follows: ISO 3864-1 similar to DIN 4844-1 ISO 7000 DIN ISO 7000 2 This standar
10、d includes safety requirements. DIN EN 869:2009-12 Amendments This standard differs from DIN EN 869:2007-02 as follows: a) The standard has been brought in line with the requirements of the new revised Machinery Directive 2006/42/EC. b) EN 964-2, EN 418, EN 294 have been replaced with the correspond
11、ing EN ISO Standards. c) Normative references have been updated to include EN 842, EN 981, EN ISO 7731, EN ISO 13732-1 and ISO 3864-1. d) Reference to EN 954-1 for control system categories has been replaced with performance levels in combination with categories according to EN ISO 13849-1. e) Annex

44、006+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 scope of this document. When provisions of this type C standard are differe
45、nt 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. !Where for clarity an example of a preventat
46、ive 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, that the equipment is operated and maintained by trained personnel.“ 1
47、 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 and dosing furnaces (see EN 746-1), metal feeding equipment, inserting a
48、nd 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 pressure diecasting machines and/or gravity diecasting machines. This standa
49、rd 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 Clause 4). It provides the requirements to be met by the manufacturer to ensure the safety of persons and
