This European Standard shall be given the status of a national standard, either by publication of a
29、n identical text or by endorsement, at the latest by August 2008, and conflicting national standards shall be withdrawn at the latest by August 2008. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be
30、held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directives 98/37/EC and 2006/42/EC. For relationship with EU Dire
31、ctives, see informative Annex ZA and ZB, which are an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic,
32、Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 14886:2008-06 EN 14886:2008 (E) 5 Introduction Thi
33、s European Standard is a type C standard as stated in EN ISO 12100-1. The machinery concerned and the extent to which hazards, hazardous situations and events are covered is indicated in the scope of this document. For the machines which are covered by the scope of this type C standard and which hav
34、e been designed and built in accordance with the provisions of this standard, the provisions of this type C standard will take precedence over the provisions of any other type B standard. DIN EN 14886:2008-06 EN 14886:2008 (E) 6 1 Scope This European standard applies to machines that are designed sp
35、ecifically to cut, split or peel block foams to commercially required shapes, using a single or double cut. All hazards listed in clause 4 are covered by this document. Cutting of block foams may be by: vertical cutting; horizontal cutting; inclined cutting; transverse cutting; contour cutting; or a
36、 combination of the above. The material to be cut may be supported or transported by: a fixed table; a shuttle table; a conveyor; a turntable; rollers; mandrel; or a combination of the above. Cutting can be either manual or automatic. Cutting tools can be: smooth-edged or toothed bandknives; cutting
37、 wires. Movement of the cutting tool can be either oscillating or continuous in one direction. This European Standard does not apply to: laser and water jet cutting; hot wire cutting; wood, metal and food cutting machines. DIN EN 14886:2008-06 EN 14886:2008 (E) 7 The safety requirements for the addi
38、tional hazards arising from the interaction between bandknife cutting machines and ancillary equipment, especially loading and unloading devices, are specified. The safety requirements for the ancillary equipment itself are not specified. This European Standard covers machines used for cutting plast
39、ics and rubber having a cellular or compact structure. However, it may also be applied when these machines are used for cutting other materials, for example textiles, fibres and mineral wool, if cutting these materials does not create additional hazards. This document is not applicable to bandknife
