35、ean foreword This document (EN 13236:2010+A1:2015) 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 endorsem
36、ent, at the latest by June 2016 and conflicting national standards shall be withdrawn at the latest by June 2016. 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
37、 or all such patent rights. The provisions of this European Standard need not be mandatory to superabrasive products manufactured the first 12 months after publication of this European Standard. This document includes Amendment 1 approved by CEN on 17 November 2015. This document supersedes !EN 1323
38、6:2010“. The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. !Significant changes between EN 13236:2001 and EN 13236:2010 were as follows:“ a) the standard was technically and editorially revised and partly adapted to EN 12413:2007 about bonded abrasi
39、ve products and EN 13743:2009 about coated abrasive products; b) the term “burst speed factor“ was included in Table 2, Table 5, Table 7 and Table 13; c) in the requirements it is now distinguished between precision and non-precision cutting-off wheels; d) new 5.3.5.3 defines restrictions in design
40、and position of cuts and openings in the metal blank of cutting-off wheels for hand-held applications; e) changed 5.3.6.2 on dimensional limitations and bending moment for segmented non-precision cutting-off wheels for hand-held applications, with requirements now depending on segment height and seg
41、ment length; f) requirements for reconditioned non-precision cutting-off wheels were included in new 5.3.6.4 and new normative Annex D; g) Clause 6 was shortened to verification of safety requirements. The scope of inspection and testing has been deleted because it is the responsibility of the manuf
42、acturer to put in place respective test procedures that give them the confidence that all safety requirements defined in this standard are respected; h) the requirements for colour code stripes were deleted in Annex A and are now presented in new Annex B; i) Table A.3 and Table A.4 about restriction
43、s for use were combined to one table and thereby adapted to EN 12413 and EN 13743; j) Clause A.2 about execution of the marking was simplified; DIN EN 13236:2016-05 EN 13236:2010+A1:2015 (E) 6 k) Annex B about blotters was deleted and part of its content was included in 5.2.5; l) Annex C about mount
44、ed points was completely revised and shortened; m) Annex D with the speed conversion table (now Annex E) was editorially revised and maximum operating speeds above 320 m/s were deleted; n) Annex E about shapes and dimensions of grinding wheels and cutting-off wheels had become obsolete with publicat
45、ion of ISO 6104 and was therefore deleted; o) Annex F about grain sizes and concentration for diamond and cubic boron nitride had become obsolete with publication of ISO 6106 and was therefore deleted. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the fol
46、lowing countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,

DIN EN 13236:2016-05 EN 13236:2010+A1:2015 (E) 7 Introduction This European Standard has been prepared to provide one means of conforming with essential safety requirements, e.g. of the
48、 General Product Safety Directive and associated EFTA regulations. This European Standard is addressed to designers, manufacturers and suppliers of the superabrasive products described in the scope as well as to those who are reconditioning superabrasive cutting-off wheels. In addition, it helps des
49、igners, manufacturers and suppliers of grinding machines in the selection of superabrasive products, in order to reduce the risks and achieve conformity of the respective machinery with the Essential Safety Requirements of the Machinery Directive. The extent to which hazards are covered is indicated in the scope of this European Standard. DIN EN 13236:2016-05 EN 13236:2010+A1:2015 (E) 8 1 Scope !This European Standa
