This European Standard has been prepared by Technical Committee CEN/TC 129 "Glass in building", the cretariat of which is held by IBN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorment, at the latest by December 2000, and conflicting national standards shall be withdrawn at the latest by December 2000.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

Introduction
Thermally toughened soda lime silicate safety glass has a safer breakage behaviour when compared with annealed glass. When it should be ud to offer protection under accidental human i
mpact, thermally toughened soda lime silicate safety glass also should be classified according to prEN 12600.
NOTE. CEN/TC129/WG8 is producing standards for the determination of the design strength of glass and is preparing a design method.
锦州翻译公司NOTE. CEN/TC129/WG2 is preparing a standard for production control and evaluation of conformity.
1Scope
This European Standard specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened soda lime silicate safety glass for u in buildings.
Information on curved thermally toughened soda lime silicate safety glass is given in annex B, but this product does not form part of this standard.
Other requirements, not specified in this standard, may apply to thermally toughened soda lime silicate safety glass which is incorporated into asmblies, e.g. laminated glass or insulating units, or
cskaundergo an additional treatment, e.g. coating. The additional requirements are specified in the appropriate product standard. Thermally toughened soda lime silicate safety glass, in this ca, does not lo its mechanical or thermal characteristics.
2Normative References
This European Standard incorporates by dated or undated reference, provisions from other publications. The normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subquent amendments to be revisions of any of the publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies.

EN 12150-1:2000 3Definitions
For the purpos of this European Standard the following definitions apply:-
3.1thermally toughened soda lime silicate safety glass: Glass within which a permanent surface compressive stress has been induced by a controlled heating and cooling process in order to give it greatly incread resistance to mechanical and thermal stress and prescribed fragmentation characteristics.
3.2flat thermally toughened soda lime silicate safety glass: Thermally toughened soda lime silicate safety glass which has not been deliberately given a specific profile during manufacture.
3.3enamelled thermally toughened soda lime silicate safety glass: Thermally toughened soda lime silicate safety glass which has a ceramic frit fired into the surface during the toughening process. After toughening the ceramic frit becomes an integral part of the glass.
NOTE. In the UK, this glass is also known as opaque thermally toughened soda lime silicate safety glass.
3.4horizontal toughening: Process in which the glass is supported on horizontal rollers.
3.5vertical toughening: Process in which the glass is suspended by tongs.
4Glass products
Thermally toughened soda lime silicate 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
- coated glass according to EN 1096-1.
Other nominal thickness of glass than tho covered in the above standards are possible.
5Fracture characteristics
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 : Fragmentation in rvice does not always correspond to that described in clau 8, due to restraint from fixing or reprocessing (e.g. laminating), or due to the cau of fracture.
