When it sho

33、9 482 Page 5 EN 12150-1:2000 3 Definitions For the purposes of this European Standard the following definitions apply. 3.1 thermally 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 or
34、der to give it greatly increased resistance to mechanical and thermal stress and prescribed fragmentation characteristics 3 . 2 safety glass which has not been deliberately given a specific profile during manufacture flat thermally toughened soda lime silicate safety glass: thermally toughened soda
35、lime silicate 3.3 enamelled 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
36、, this glass is also known as opaque thermally toughened soda lime silicate safety glass. 3.4 horizontal toughening: process in which the glass is supported on horizontal rollers 3.5 vertical toughening: process in which the glass is suspended by tongs 4 Glass products Thermally toughened soda lime
37、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 a
38、ccording to EN 1096-1. Other nominal thicknesses of glass than those covered in the above standards are possible. 5 Fracture 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. NOT
39、E: Fragmentation in service does not always correspond to that described in clause 8, due to restraint from fixing or reprocessing (e.g. laminating), or due to the cause of fracture. 6 Dimensions and tolerances 6 . 1 Nominal thickness and thickness tolerances The nominal thicknesses and thickness to
40、lerances are those given in the relevant product standard (see clause 4 ) , some of which are reproduced in Table 1.

For special requirements, the manufacturer should be consulted. 6.3.2 Measurement of overall bow The pane of glass shall be placed in a vertical position and supported on its longe
43、r side by two load bearing blocks at the quarter points (see Figure 5). The deformation shall be measured along the edges of the glass and along the diagonals, as the maximum distance between a straight metal ruler, or a stretched wire, and the concave surface of the glass (see Figure 4 ) .

47、urement of overail bow 6.3.3 Measurement of local bow Local bow can occur over relatively short distances on the edges of the glass. Local bow shall be measured over a limited length of 300 mm by using a straight ruler, or a stretched wire, parallel to the edge at a distance of 25 mm from the edge o
48、f the glass (see Figure 4). Local bow is expressed as millimetres/300 mm length. For patterned glass, local bow shall be determined by using a straight ruler resting on the high points of the pattern and measuring to a high point of the pattern. 6.3.4 Limitation on overall and local bow The maximum
49、allowable values for the overall bow, when measured according to 6.3.2, and local bow, when measured according to 6.3.3, for glass without holes and/or notches andor cut-outs are given in Table Q BSI 08-2000 Copyright European Committee for Standardization Provided by IHS under license with CEN Not for ResaleNo reproduction or networking permitted without license from IHS -
