30、2 EN 13024-1:2011 (E) 5 Introduction Thermally toughened borosilicate safety glass has a higher thermal shock resistance and a safer breakage behaviour when compared with annealed glass. When it should be used to offer protection under accidental human impact, thermally toughened borosilicate safety

31、 glass also should be classified according to EN 12600. NOTE CEN/TC 129/WG 8 is producing standards for the determination of the design strength of glass and is preparing a design method. DIN EN 13024-1:2012-02 EN 13024-1:2011 (E) 6 1 Scope This European Standard specifies tolerances, flatness, edge

32、work, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened borosilicate safety glass for use in buildings. Information on curved thermally toughened borosilicate safety glass is given in Annex A, but this product does not form part of this standard. Other

33、requirements, not specified in this standard, can apply to thermally toughened borosilicate safety 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 appropria

34、te product standard. Thermally toughened borosilicate safety glass, in this case, 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 app

38、cific profile during manufacture NOTE The information is given in Annex A. 3.2 edge deformation deformation of the edge because of the tong marks 3.3 edge lift (also referred to as edge dip) distortion produced in horizontal toughened glass, at the leading and trailing edge of the plate NOTE This is

39、 a distortion produced by a reduction in surface flatness. DIN EN 13024-1:2012-02 EN 13024-1:2011 (E) 7 3.4 enamelled thermally toughened borosilicate safety glass thermally toughened borosilicate safety glass which has a ceramic frit fired into the surface during the toughening process NOTE 1 After

40、 toughening, the ceramic frit becomes an integral part of the glass. NOTE 2 In the UK, this glass is also known as opaque thermally toughened borosilicate safety glass. NOTE 3 The application of the ceramic frit may be by a continuous process or discontinuous application, e.g. screen printing. The e

41、namelled surface could be partially or wholly covered. 3.5 flat thermally toughened borosilicate safety glass thermally toughened borosilicate safety glass which has not been deliberately given a specific profile during manufacture 3.6 thermally toughened borosilicate safety glass glass within which

42、 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 greatly increased resistance to mechanical and thermal stress and prescribed fragmentation characteristics NOTE The mechanical prop

43、erties, i.e. thermal durability and mechanical strength, and safety properties, i.e. fragmentation characteristics, 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 loc

44、al distortion local deformation of vertically toughened glass underneath the tong marks 3.9 overall bow deformation of the whole pane of horizontally and vertically toughened glass caused by the heating and cooling process 3.10 roller wave distortion distortion produced in horizontally toughened gla

45、ss as a result of the glass during the toughening 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 suspended by tongs 4 Glass products Thermally toughened borosilicate safety g

46、lass is made from a monolithic glass generally corresponding to one of the following standards: borosilicate glass according to EN 1748-1-1; coated glass according to EN 1096-1. DIN EN 13024-1:2012-02 EN 13024-1:2011 (E) 8 Glass of nominal thicknesses other than those covered in the above standards

47、is possible. 5 Fracture characteristics The fracture characteristics of thermally toughened borosilicate safety glass are directly related to the amount of surface compression; these properties are not size dependent. When the thermally toughened borosilicate safety glass is manufactured with the co

48、rrect degree of surface compression then in the event of breakage thermally toughened borosilicate safety glass fractures into numerous small pieces, the edges of which are generally blunt. NOTE 1 The degree of surface compression required is dependent upon glass type and thickness. NOTE 2 The fracture characteristics of glass are unaffected by temperatures between 50 C and + 100 C. The frag
