18、g”, the secretariat of which is held by NBN. 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of an identical text or by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the latest by May 2012. Attention is
19、 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 1863-1:2000. This document has been prepared under a mandate given to
20、CEN by the European Commission and the European Free Trade Association.

21、t 2: Evaluation of conformity/Product standard. This European Standard differs from EN 1863-1:2000 as follows: a) some figures have been revised and some new figures have been added; b) new terms and definitions have been included in Clause 3, e.g. edge deformation (3.2), local distortion (3.8) and
22、overall bow (3.9); c) further nominal thicknesses have been included in Table 1; d) Subclause 6.2.3 “Tolerances and squareness“ has been completely revised; the squareness of rectangular glass panes is now expressed by the difference between its diagonals; e) Clauses 6 and 7 have been completely rev
23、ised; f) the previous Clauses 9 and 10 have been revised and have been combined in a new Clause 9 “Other physical characteristics“; g) the normative Annex “Determination of U value“ has been deleted; h) a new informative Annex dealing with an alternative method for the measurement of roller wave dis
24、tortion has been added.

BS EN 1863-1:2011EN 1863-1:2011 (E) 5 Introduction Heat strengthened soda lime silicate glass has a higher res
26、istance to thermal stress and an enhanced mechanical strength when compared to annealed glass. NOTE CEN/TC 129/WG 8 is producing standards for the determination of the design strength of glass and is preparing a design method. BS EN 1863-1:2011EN 1863-1:2011 (E) 6 1 Scope This European Standard spec
27、ifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat heat strengthened soda lime silicate glass of nominal thicknesses from 3 mm to 12 mm for use in buildings. Other requirements, not specified in this standard, can apply to heat strength
28、ened soda lime silicate glass which is incorporated into assemblies, e.g. laminated glass or insulating glass units, or undergo an additional treatment, e.g. coating. The additional requirements are specified in the appropriate product standard. Heat strengthened soda lime silicate glass, in this ca
29、se, does not lose its mechanical or thermal characteristics. This European Standard does not cover glass sandblasted after toughening. 2 Normative references The following referenced documents are indispensable for the application of this document.

33、 document, the following terms and definitions apply. 3.1 curved heat strengthened soda lime silicate glass heat strengthened soda lime silicate glass which has been deliberately given a specific profile during manufacture 3.2 edge deformation deformation of the edge because of the tong marks 3.3 ed
34、ge lift (also referred to as edge dip) distortion produced in horizontal heat strengthened glass, at the leading and trailing edge of the plate NOTE This is a distortion produced by a reduction in surface flatness. BS EN 1863-1:2011EN 1863-1:2011 (E) 7 3.4 enamelled heat strengthened soda lime silic
35、ate glass heat strengthened soda lime silicate glass which has a ceramic frit fired into the surface during the heat strengthening process NOTE 1 After heat strengthening the ceramic frit becomes an integral part of the glass. NOTE 2 In the UK, this glass is also known as opaque heat strengthened so
36、da lime silicate glass. NOTE 3 The application of the ceramic frit may be by a continuous process or discontinuous application, e.g. screen printing. The enamelled surface could be partially or wholly covered. 3.5 flat heat strengthened soda lime silicate glass heat strengthened soda lime silicate g
37、lass which has not been deliberately given a specific profile during manufacture 3.6 heat strengthened soda lime silicate glass glass within which a permanent surface compressive stress, additionally to the basic mechanical strength, has been induced by a controlled heating and cooling process in or
38、der to give it increased resistance to mechanical and thermal stress and prescribed fracture characteristics NOTE The thermal durability and mechanical strength are generated by the level of surface compression. These properties are not size dependent. 3.7 horizontal process process in which the gla
39、ss is supported on horizontal rollers 3.8 local distortion local deformation of vertically heat strengthened glass underneath the tong marks 3.9 overall bow deformation of the whole pane of horizontally and vertically heat strengthened glass caused by the heating and cooling process 3.10 roller wave
40、 distortion distortion produced in horizontal heat strengthened glass as a result of the glass during heat strengthening process being in contact with the rollers NOTE This is a surface distortion produced by a reduction in surface flatness. 3.11 vertical process process in which the glass is suspen
41、ded by tongs 4 Glass products Heat strengthened soda lime silicate glass is made from a monolithic glass generally corresponding to one of the following standards: soda lime silicate glass according to EN 572-1; float glass according to EN 572-2; BS EN 1863-1:2011EN 1863-1:2011 (E) 8 drawn sheet gla
42、ss according to EN 572-4; patterned glass according to EN 572-5; supplied and final cut sizes according to EN 572-8; coated glass according to EN 1096-1. Glass of nominal thicknesses between 3 mm and 12 mm other than those covered in the above standards are possible. 5 Fracture characteristics In th
43、e event of breakage, heat strengthened soda lime silicate glass fractures in a manner similar to annealed glass (see Clause 8). The fragmentation described in Clause 8 is undertaken on unrestrained test specimens. The fragmentation in service may not always correspond to that determined during the f
44、ragmentation test due to the imposition of other stresses, i.e. from fixing or from reprocessing (e.g. laminating). NOTE The fracture characteristics of glass are unaffected by temperatures between 50 C and + 100 C. 6 Dimensions and tolerances 6.1 Nominal thickness and thickness tolerances The nomin
45、al thicknesses and thickness tolerances are those given in the relevant product standard (see Clause 4), some of which are reproduced in Table 1.
