19、UNI. 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of an identical text or by endorsement, at the latest by June 2015, and conflicting national standards shall be withdrawn at the latest by June 2015. Attention is drawn to the possibility that some of

20、 the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1417:1996+A1:2008. This document has been prepared under a mandate given to CEN by the European Commission a

21、nd the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Compared with EN 1417:1996+A1:2008, the following significant technical changes have been made:

22、 a distinction has been made between large, intermediate and small two-roll mills; automatic separation has been made mandatory for two-roll mills equipped with a trip bar; however, mill roll reversal can be associated with automatic separation; the performance levels of safety related parts of cont

23、rol systems have been specified in accordance with EN ISO 13849-1:2008; the simplification of the definition of the stopping angle; technical developments in safeguards have been taken into account e.g. light curtains, positioning of interlocking guards; the addition of requirements regarding emerge

24、ncy stops; the addition of hazards due to electromagnetic interference; the addition of a noise test code. 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, Cro

29、acturer (see Clause 4). This European Standard covers two-roll mills as defined in 3.1. This European Standard does not deal with the design of a local exhaust ventilation system that may be necessary in specific applications of the machine not known by the manufacturer.
