DIN EN 1863-1:2012-02 EN 1863-1:2011 (E) 5 Introduction Heat strengthened soda lime silicate glass has a higher resistance t
30、o 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. DIN EN 1863-1:2012-02 EN 1863-1:2011 (E) 6 1 Scope This European Standard specifie
31、s 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 strengthened
32、 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 case,
33、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.

38、ift (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.

39、cate 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 s
40、oda 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
41、glass 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 o
42、rder 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 gl
43、ass 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 wav

45、nded 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; DIN EN 1863-1:2012-02 EN 1863-1:2011 (E) 8 drawn she
46、et glass 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
47、 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
48、 the fragmentation 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
49、 nominal thicknesses and thickness tolerances are those given in the relevant product standard (see Clause 4), some of which are reproduced in Table 1.
