27、 The mechanical properties, i.e. thermal durability and profile bending strength, and safety properties, i.e. fragmentation characteristics, are generated by the level of surface compression. These properties do not depend on the size of the channel shaped glass. 3.2 enamelled thermally toughened so

31、unt. NOTE Fragmentation in service does not always correspond to that described in Clause 8, due to restraint from fixing or due to the cause of fracture. 6 Dimensions and tolerances 6.1 General The dimensions of thermally toughened soda lime silicate channel shaped safety glass are shown in Figure
32、1. These are glass thickness (c), width (B), length (H) and flange height (d). 6.2 Dimensions and dimensional tolerances 6.2.1 Nominal thickness (c) and thickness tolerances The nominal thicknesses and thickness tolerances shall be those given in Table 1. NOTE The tolerances of width, height of flan
33、ge and thickness are those given in EN 572-7:2012, Table 1. Table 1 of EN 15683-1:2012 was extended by the length H. The thickness shall be determined as for the basic product. 6.2.2 Width, flange height and length (sizes) 6.2.2.1 General Thermally toughened soda lime silicate channel shaped safety
34、glass dimensions are quoted as follows: the type which defines the width, B, the flange height, d, and the thickness, c; and the length, H. EXAMPLE 232/41/6 4 000.

38、 deviation The deviation of the flange, z, from perpendicular to the web is determined with a right angle, as shown in Figure 2. BS EN 15683-1:2013EN 15683-1:2013 (E) 8 Key z flange deviation Figure 2 Determination of flange deviation 6.3.2 Squareness of cut, q The out of squareness of the web and f
39、langes is determined at both cut ends. It is measured relative to a plane perpendicular to the direction of draw of the glass at the intersection of the centre line of the web and of the cut edge (see Figure 3). The deviation of the flange plane is measured. Key q squareness of cut Figure 3 Determin
40、ation of squareness of cut 6.3.3 Tolerances on shape The tolerance on flange deviation, z, shall not exceed 1,0 mm. The deviation on squareness of cut, q, shall not exceed 3,0 mm. 6.4 Flatness 6.4.1 General By the very nature of the toughening process, it is not possible to obtain a product as flat
41、as annealed glass. The difference depends on the nominal thickness, the web and flange dimensions and the length. Therefore, a distortion known as overall bow may occur (see Figure 4). NOTE Overall bow can, in general, be accommodated by the framing system. BS EN 15683-1:2013EN 15683-1:2013 (E) 9 Ke

The deformation
43、 shall be measured along the middle axis of the web between the cut edges of the channel shaped glass as the maximum distance between a straight metal ruler, or a stretched wire, and the concave surface of the channel shaped glass (see Figure 4). The value for the bow is then expressed as the deform
44、ation, in millimetres, divided by the measured length of the channel shaped glass in millimetres. The measurement shall be carried out at ambient temperature.

46、ed, drilled or edge worked after toughening. The cut edges have to be edge worked prior to toughening. The simplest type of edge working is the arrissed edge (see Figure 6). Figure 6 Arrissed edge (with blank spots) BS EN 15683-1:2013EN 15683-1:2013 (E) 11 8 Fragmentation test 8.1 General The fragme
47、ntation test determines whether the glass breaks in the manner prescribed for a thermally toughened soda lime silicate channel shaped safety glass. 8.2 Dimensions and number of test specimens The length (H) of the test specimens shall be 2 100 mm. The width is determined by the glass type. The test
48、specimen shall be taped on the external surface to stop the fragments separating but still allowing the specimen to expand when fragmented. Five specimens shall be tested. 8.3 Test procedure The test specimen is placed web side down on a flat surface. Each test specimen shall be impacted, using a po
49、inted steel tool, at a position 13 mm in from the cut edge of the test specimen at the mid-point of that edge, until breakage occurs (see Figure 7). NOTE The fragmentation characteristics of glass are unaffected by temperatures between 50 C and +100 C. Examples of steel tools are a hammer of about 75 g mass, a spring loaded centre punch, or other similar appliance with a hardened point. The radius of curvature of the point should be approximately 0,2 mm. The test specimen shall be laid flat on a table withou
