This
21、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of an identical text or by endorsement, at the latest by May 2012, and conflicting national standards shall be withdrawn at the latest by May 2012.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 drawn to the possibility that some of the element
22、s 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 CEN by the European Commission and the European Fr
23、ee Trade Association. EN 1863 is divided into the following parts: EN 1863-1, Glass in building Heat strengthened soda lime silicate glass Part 1: Definition and description; EN 1863-2, Glass in building Heat strengthened soda lime silicate glass Part 2: Evaluation of conformity/Product standard. Th
24、is 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 overall bow (3.9); c) further nominal thicknesses
25、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 revised; f) the previous Clauses 9 and 10 have been r
26、evised 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 distortion has been added. According to the CEN/CENEL
27、EC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania

NOTE CEN/TC 129/WG 8 is producing standards for the determination of the design stren
30、gth of glass and is preparing a design method.

31、rances, 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 strengthened soda
32、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 case, does n
33、ot 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. For dated references, only the edition cited applies. For und

37、 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 edge lift (a
38、lso 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.

40、OTE 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 soda lime silicate glass. NOTE 3 The application of the ceramic frit may be by a continuous process or discontinuous application, e.g. screen
41、printing. The enamelled surface could be partially or wholly covered. 3.5 flat heat strengthened soda lime silicate glass heat strengthened soda lime silicate glass which has not been deliberately given a specific profile during manufacture 3.6 heat strengthened soda lime silicate glass glass within
42、 which a permanent surface compressive stress, additionally to the basic mechanical strength, has been induced by a controlled heating and cooling process in order to give it increased resistance to mechanical and thermal stress and prescribed fracture characteristics NOTE The thermal durability and
43、 mechanical strength are generated by the level of surface compression. These properties are not size dependent. 3.7 horizontal process process in which the glass is supported on horizontal rollers 3.8 local distortion local deformation of vertically heat strengthened glass underneath the tong marks
44、 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 distortion distortion produced in horizontal heat strengthened glass as a result of the glass during heat strengthening process being in co

48、Fracture characteristics In the 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 fragmentation test due to the imposition of other stresses, i.e. from fixing or from reprocessing (e.g. laminating).
