    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.
