24、Part 1: Definitions and general physical and mechanical properties 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 572-1:2012 and the following apply. 3.1 patterned channel shaped glass channel shaped glass with a pattern on the web surface Note 1 to
25、entry: A number of different patterns are available. Note 2 to entry: Patterns might be on one or both surfaces of the web. 3.2 wired channel shaped glass channel shaped glass which has a wire inlay in the web Note 1 to entry: This means that the wire runs across the width, B, and in the direction o
26、f the length, H. Note 2 to entry: Additional wires might also be in the flanges. 3.3 length, H, width, B, and flange height, d defined with reference to the direction of draw of the glass ribbon as shown in Figure 1 Note 1 to entry: All corners are rounded.

27、ey 1 direction of draw Figure 1 Relationship between U-channel dimensions and direction of draw 3.4 stock sizes glass delivered in the standard stock sizes: nominal length, H: supplied in multiples of 250 mm; nominal width, B: range from 232 mm to 498 mm; nominal height of flange, d: either 41 mm or
28、 60 mm Note 1 to entry: Maximum length, H, available: 7 000 mm. Note 2 to entry: Not all widths, B, are available with all flange heights, d. 3.5 visual fault fault which alters the visual quality of the glass Note 1 to entry: Visual faults include bubbles, ream, scratches and inclusions and where a
29、pplicable wire faults. 3.6 flange deviation deviation, z, of flange from the vertical Note 1 to entry: See Figure 2. 3.7 wire fault deviation of the wire resulting in penetration of the glass surface by the wire or break in the wire in the body of the glass 3.8 deviation of the wire deviation, y, of
30、 the wire relative to a reference such as a line or straight edge Note 1 to entry: See Figure 4. DIN EN 572-7:2012-11 EN 572-7:2012 (E) 6 4 Dimensional requirements 4.1 Method of measurement 4.1.1 Width, B, and height of flange, d The width and height of flange are measured at both cut ends of the p
31、iece using a vernier calliper with an accuracy of 0,1 mm. 4.1.2 Length, H The length is measured at the centre of the web. 4.1.3 Thickness, c The actual thickness is measured at both cut ends. Measurements, to an accuracy of 0,1 mm, are made in the centre of the web and flanges. Measurement should b
32、e made by means of an instrument of the plate gauge type with a diameter of (50 5) mm. 4.1.4 Flange deviation The deviation of the flange, z, from perpendicular to the web is determined with a right angle, as shown in Figure 2.

33、:2012 (E) 7 4.1.5 Squareness of cut The out of squareness of the web and flanges 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
34、of the flange plane is measured. Figure 3 Determination of squareness of cut 4.1.6 Wire inlay The relationship between the width of the wire inlay, in the web, and the width, B, of the web should be obtained by measurement. The actual distance between adjacent wires should be measured together with
35、any variation in the spacing. The diameter of the wire should be measured. 4.2 Tolerances 4.2.1 Width, B, height of flange, d, and thickness c All measured values shall comply with Table 1. 4.2.2 Length The tolerance on measured length, H, is 3,0 mm. 4.2.3 Flange deviation The flange deviation, z, (
36、see Figure 2) should not exceed 1,0 mm. 4.2.4 Squareness of cut The deviation of the squareness of cut (see Figure 3) shall not exceed 3 mm. 4.2.5 Wire inlay The wire inlay shall cover at least 75 % of the web width, B. The maximum distance between adjacent wires shall not exceed 35 mm. The allowabl
37、e tolerance between adjacent wires is 6 mm. The diameter of the wire should be between 0,3 mm and 0,7 mm.

38、lts. 5.2 Methods of observation and measurement 5.2.1 Visual faults The piece of channel shaped glass to be examined is illuminated in conditions approximating to diffuse daylight and is observed in front of a white background. Place the glass to be examined vertically in front of the screen. Arrang
39、e the point of observation 2 m from the glass, keeping the direction of observation normal to the glass surface. Note the presence of bubbles, ream, scratches and inclusions.

The deviation, y, of the wire inlay in relation to this refer
41、ence edge is measured (see Figure 4). Any penetration of the glass surface by the wire is noted. Any breaks in the wire are noted. a) Out of square b) Waviness c) BowNOTE The scale of these drawings has been exaggerated in order to be explicit about the types of deviation.
