This European Standard shall be given the sta
21、tus of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2016, and conflicting national standards shall be withdrawn at the latest by March 2016. Attention is drawn to the possibility that some of the elements of this document may be the subjec
22、t of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12150-1:2000. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. EN 12150, Gla
23、ss in building Thermally toughened soda lime silicate safety glass, consists of the following parts: Part 1: Definitions and description; Part 2: Evaluation of conformity/Product standard. This European Standard differs from EN 12150-1:2000 as follows: a) some figures have been revised and some new
24、figures have been added; b) new terms and definitions have been included in Clause 3, e.g. air cushion process (3.6), edge lift (3.9) and roller wave distortion (3.13); c) further nominal thicknesses have been included in Table 1; d) Subclause 6.2.3 “Tolerances and squareness” has been completely re
25、vised; the squareness of rectangular glass panes is now expressed by the difference between its diagonals; e) Clauses 6 and 7 have been completely revised (including the air cushion manufacturing process); f) the normative annex “Determination of U value” has been deleted; g) a new informative annex
26、 dealing with an alternative method for the measurement of roller wave distortion has been added. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyp

28、d Kingdom. BS EN 12150-1:2015EN 12150-1:2015 (E) 5 Introduction Thermally toughened soda lime silicate safety glass has a safer breakage behaviour when compared with annealed glass. When it should be used to offer protection under accidental human impact, thermally toughened soda lime silicate safet
29、y 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. BS EN 12150-1:2015EN 12150-1:2015 (E) 6 1 Scope This European Standard specifies tolerances, flatness, edgework
30、, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened soda lime silicate safety glass for use in buildings. Information on curved thermally toughened soda lime silicate safety glass is given in Annex A, but this product does not form part of this European
31、 Standard. Other requirements, not specified in this European Standard, can apply to thermally toughened soda lime silicate 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 requirement
32、s are specified in the appropriate glass product standard. Thermally toughened soda lime silicate safety glass, in this case, does not lose its bending strength characteristics and its resistance to temperature differentials. Surface finished glasses (e.g. sandblasted, acid etched) after toughening
33、are not covered by this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of t

37、 the purposes of this document, the following terms and definitions apply. 3.1 thermally toughened soda lime silicate safety glass thermally toughened safety glass glass within which a permanent surface compressive stress, additionally to the basic mechanical strength, has been induced by a controll
38、ed heating and cooling process in order to give it greatly increased resistance to mechanical and thermal stress and prescribed fragmentation characteristics BS EN 12150-1:2015EN 12150-1:2015 (E) 7 Note 1 to entry: The mechanical properties, i.e. thermal durability and mechanical strength, and safet
39、y properties, i.e. fragmentation characteristics, are generated by the level of surface compression. These properties are not size dependent. 3.2 flat thermally toughened soda lime silicate safety glass thermally toughened soda lime silicate safety glass which has not been deliberately given a speci
40、fic profile during manufacture 3.3 curved thermally toughened soda lime silicate safety glass thermally toughened soda lime silicate safety glass which has been deliberately given a specific profile during manufacture Note 1 to entry: See Annex A. 3.4 enamelled thermally toughened soda lime silicate
41、 safety glass thermally toughened soda lime silicate safety glass which has a ceramic frit fired into the surface during the toughening process Note 1 to entry: After toughening the ceramic frit becomes an integral part of the glass. Note 2 to entry: In the UK, this glass is also known as opaque the
42、rmally toughened soda lime silicate safety glass. Note 3 to entry: 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. 3.5 horizontal process process in which the glass is supported
43、 on horizontal rollers 3.6 air cushion process process in which the glass is supported by an air cushion with or without additional rollers Note 1 to entry: In this process the glass will be between horizontal and 45 of horizontal. 3.7 vertical process process in which the glass is suspended by tong
44、s 3.8 edge deformation deformation of the edge cause by the tong marks for vertically toughened glass 3.9 edge lift distortion produced in horizontal toughened glass, at the leading and trailing edge of the plate 3.10 perimeter deformation distortion around the edge of toughened glass manufactured b

47、cate safety 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; drawn sheet glass according to EN 572-4; patterned glass according to EN 572-5; supplied and final cut sizes
48、 according to EN 572-8; coated glass according to EN 1096-1. Glass of nominal thicknesses other than those covered in the above standards is possible. 5 Fracture characteristics The fracture characteristics of thermally toughened soda lime silicate safety glass are directly related to the amount of
49、surface compression. These properties are not size dependent. When the thermally toughened soda lime silicate safety glass is manufactured with the correct degree of surface compression then in the event of breakage thermally toughened soda lime silicate 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 +
