40、e 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of an identical text or by endorsement, at the latest by June 2016 and conflicting national standards shall be withdrawn at t
41、he 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 or all such patent rights. The provisions of this European Standard need not be mandatory
42、 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 13236:2010“. The start and finish of text introduced or altered by amendment is indicated in t
43、he 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 abrasive products and EN 13743:2009 about coated abrasive products; b) the term “burst speed fac
44、tor“ 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 and position of cuts and openings in the metal blank of cutting-off wheels for hand-held a
45、pplications; 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 segment length; f) requirements for reconditioned non-precision cutting-off wheels were inclu
46、ded 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 manufacturer to put in place respective test procedures that give them the confidence that all
47、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 restrictions for use were combined to one table and thereby adapted to EN 12413 and EN 13743; j) Clau
48、se A.2 about execution of the marking was simplified; BS EN 13236:2010+A1:2015EN 13236:2010+A1:2015 (E)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 mounted points was completely revised and shortened; m) Annex D wit
49、h 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 publication 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.
