EN 13743:2009 (E) 3 Foreword This document (EN 13743:2009) has been prepared by Technical Committee CEN/TC 143 “Machine tools - Safety”, the secretariat of which is held by SNV. 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of an identical text or by endorsement, at the latest by January 2010, and conflicting national standards shall be withdrawn at the latest by January 2010. 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 held responsible for identifying any or all such patent rights. This document supersedes EN 13743:2001. Significant changes against EN 13743:2001 are as follows: a) The standard was technically and editorially revised and partly adapted to EN 12413:2007 on bonded abrasive products; b) Table 2 with dimensional abbreviations was deleted; c) "Vibration" was included in the list of hazards in Table 3; d) Table 5 (now Table 4) containing maximum operating speeds and safety factors was simplified and burst speed factors were given instead of minimum bursting speed; e) Table 6 (now Table 5) with dimensional limitations and maximum operating speeds was simplified by abandoning the distinction between standard operating speeds and special operating speeds;
f) Clause 6 on verification and inspection was shortened, 6.1.1 and 6.1.2 about safety speed test and bursting speed test were combined to a new 6.2, thereby deleting Table 7 with maximum operating speeds and safety test speeds; g) 6.2 on scope of the inspection was deleted together with Table 8; h) Clause 7 on information for use was shortened; i) the requirements for colour code stripes were deleted in Annex A and are now presented in a new Annex B; j) some values given in the speed conversion table in Annex B (now Annex C) were slightly changed. 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, 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.
