EN 14179, Glass in building Heat soaked thermally toughened soda lime silicate safety glass, is composed of the following parts: Part 1: Definition an

20、d description; Part 2: Evaluation of conformity / Product standard. This European Standard differs from EN 14179-1:2005 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. air cushion process (3.7), edg

21、e lift (3.10) and roller wave distortion (3.14) further nominal thicknesses have been included in Table 1; c) the glass temperature during the holding time of the heat soak process cycle has been reduced, d) subclause 8.2.3 “Tolerances and squareness” has been completely revised; the squareness of r

22、ectangular glass panes is now expressed by the difference between its diagonals; e) Clauses 8 and 9 have been completely revised (including the air cushion manufacturing process); f) the informative Annex “Curved heat soaked thermally toughened soda lime silicate safety glass” has been deleted; g) a

23、 new informative Annex dealing with an alternative method for the measurement of roller wave distortion has been added.

25、, Turkey and the United Kingdom. BS EN 14179-1:2016EN 14179-1:2016 (E) 5 Introduction Heat soaked thermally toughened soda lime silicate safety glass has a safer breakage behaviour when compared with annealed glass. It also has a known level of residual risk of spontaneous breakage arising from the

26、possible presence of critical nickel sulphide (NiS) inclusions in the heat soaked thermally toughened soda lime silicate glass. NOTE 1 This case deals with extremely large quantities of glass. These quantities are dealt with on a statistical basis. Therefore, it is impossible to select a quantity of

27、 heat soaked thermally toughened soda lime silicate safety glass, for a building, and claim that no break by NiS inclusion can occur. The breakage of heat soaked thermally toughened soda lime silicate safety glass caused by other influences is not considered in this European Standard. When used to o

28、ffer protection under accidental human impact, heat soaked thermally toughened soda lime silicate safety glass also should be classified according to EN 12600. NOTE 2 CEN/TC 129/WG 8 is producing standards for the determination of the design strength of glass and is preparing a design method. The Eu

29、ropean Committee for Standardization (CEN) draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning heat soak tests. CEN takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent r

30、ight has ensured CEN that he / she is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with CEN. Information may be obtained from: SAINT-GOB

31、AIN GLASS FRANCE; Les Miroirs 92096 La Dfense Cedex, Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than those identified above. CEN shall not be held responsible for identifying any or all such patent rights. CEN and CENELE

32、C maintain online lists of patents relevant to their standards. Users are encouraged to consult the lists for the most up to date information concerning patents (ftp:/ftp.cencenelec.eu/EN/IPR/Patents/IPRdeclaration.pdf). BS EN 14179-1:2016EN 14179-1:2016 (E) 6 1 Scope This European Standard specifie

33、s the heat soak process system together with tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat heat soaked thermally toughened soda lime silicate safety glass for use in buildings. Curved heat soaked thermally toughened soda lime silicate sa

34、fety glass is not part of this European Standard. Other requirements, not specified in this European Standard, can apply to heat soaked thermally toughened soda lime silicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating units, or undergo an additional treatm

35、ent, e.g. coating. The additional requirements are specified in the appropriate product standard. Heat soaked 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 glasse

36、s (e.g. sandblasted, acid etched) after toughening 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.

42、mechanical properties, i.e. thermal durability and mechanical strength, and safety properties, i.e. fragmentation characteristics, are generated by the level of surface compression.
