DIN EN 15682-1:2013-10 EN 15682-1:2013 (E) 5 Introduction Heat soaked thermally toughened alkaline earth silicate safety glass has a safer breakage behaviour when compared with annealed glass. It also has a known level
27、 of residual risk of spontaneous breakage arising from the possible presence of critical nickel sulphide (NiS) inclusions in the thermally toughened alkaline earth silicate glass. NOTE 1 In this case it is about a statistical mean out of a big quantity of glass. It is impossible to determine separat
28、ed subjects from it for a building where definitely no “break” produced by NiS occurs. The breaking of glass caused by other influences is not included herewith. When used to offer protection under accidental human impact, heat soaked thermally toughened alkaline earth silicate safety glass also sho
29、uld 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. DIN EN 15682-1:2013-10 EN 15682-1:2013 (E) 6 1 Scope This European Standard specifies the heat soak process system together w

Information on curved heat soak thermally toughened alkaline earth silicate safety glass is given
31、 in Annex B, but this product does not form part of this document. Other requirements, not specified in this document, can apply to heat soaked thermally toughened alkaline earth silicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating units, or undergo an addi
32、tional treatment, e.g. coating. The additional requirements are specified in the appropriate product standard EN 15682-2. In this case, heat soaked thermally toughened alkaline earth silicate glass does not lose its mechanical or thermal characteristics. 2 Normative references The following document

41、rom a monolithic alkaline earth silicate glass product generally corresponding to one of the following standards: coated glass according to EN 1096-1; basic alkaline earth silicate glass according to EN 14178-1. 5 Manufacturing processes 5.1 General Heat soaked thermally toughened alkaline earth sil
42、icate safety glass is manufactured as follows: Basic alkaline earth silicate glass products (see Clause 4) are cut to size, shaped and edge worked (see Clause 9). The prepared glass panes are then thermally toughened (see 5.2). The thermally toughened panes are then subjected to the heat soak proces
43、s cycle. After manufacture the heat soaked thermally toughened alkaline earth silicate glass shall comply with the fragmentation test (see Clause 10) and mechanical strength requirement (see 11.4). 5.2 Toughening process The cut, shaped and edge worked glasses are toughened. The horizontal or vertic
44、al toughened glass shall comply with the flatness criteria (see 8.3). The thermally toughened alkaline earth silicate glass shall have a level of fragmentation that will ensure that after the glass has been through the heat soak process, and subsequently tested to the fragmentation test (see Clause
45、10), it shall comply with 10.5. 5.3 Heat soak process cycle 5.3.1 General The heat soak process cycle consists of a heating phase, a holding phase and a cooling phase (see Figure 1).

47、80 C. The time to reach this temperature is defined in the calibration process. This time will be dependent on the size of the oven, the amount of glass to be treated, the separation between glasses and the heating system capacity. The glass separation and rate of heating should be controlled to min
48、imise the risk of glass breakage as a result of thermal stress. To facilitate economic heating, the air temperature within the oven may exceed 320 C. However, the glass surface temperature shall not be allowed to exceed 320 C. The period of glass surface temperature in excess of 300 C shall be minim
49、ised. When the temperature of the glass exceeds 300 C, care should be taken to ensure that the properties of the heat soaked thermally toughened alkaline earth silicate safety glass are not significantly altered, i.e. they continue to meet Clause 10. 5.3.3 Holding phase The holding phase commences when the surface temperature of all the glasses has reached a temperature of 280 C. The duration of the holding phase is minimum 2 h. Precise oven control is necess
