9、asic soda lime silicate glass products Part 6: Wired patterned glass published by the European Committee for Standardization (CEN). It does not replace any current British Standard. EN 572-6 was produced as a result of international discussions in which the United Kingdom took an active part. A Brit
10、ish Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a fron

25、lts) for wired patterned glass, as defined in EN 572-1, for use in building. This Part of this standard applies only to wired patterned glass supplied in rectangular panes and in stock sizes. This Part of this standard does not apply to glass in cut sizes for final end use. 2 Normative references Th
26、is European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publ
27、ications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

28、l properties. 3 Definitions For the purpose of this standard the following definitions apply. 3.1 length, H, and width, B these are defined with reference to the direction of draw of the glass ribbon as shown in Figure 1 3.2 stock sizes glass delivered in the following sizes: Nominal length H: 1 380
29、 mm to 4 500 mm Nominal width B: 1 500 mm to 2 520 mm 3.3 visual faults these are faults which alter the visual quality of the glass. They include spot faults, linear/extended faults, pattern faults and wire faults 3.4 spherical or quasi-spherical spot faults these are spot faults whose larger dimen
30、sion is less than or equal to twice the smaller dimension 3.5 elongated spot faults these are spot faults whose larger dimension is more than twice the smaller dimension 3.6 linear/extended faults these faults can be on or in the glass, in the form of deposits, marks or scratches which occupy an ext
31、ended length or area 3.7 pattern faults these are deviations of the pattern relative to a reference, e.g. line or straight edge 3.8 deviation of the pattern this is a deviation, x, of the pattern 3.9 wire faults these are deviations of the wire, penetration of the glass surface by the wire or break
32、in the wire in the body of the glass 3.10 deviation of the wire this is a deviation, y, of the wire relative to a reference, e.g. line or straight edge 4 Dimensional requirements 4.1 Thickness The actual thickness shall be the average of four measurements, taken to the nearest 0,01 mm, each one take
33、n at the thickest and closest point to the centre of each side. Measurement shall be by means of an instrument of the plate gauge type with a diameter of 50 mm 5 mm. NOTEThe mechanical resistance of wired patterned glass is a function of the pattern as well as the thickness. Figure 1 Relationship be

35、the tolerances shown in Table 1. Table 1 Tolerances on nominal thickness 4.2 Length, width and squareness The nominal dimensions for length, H, and width, B, being given, the pane shall not be larger than a prescribed rectangle resulting from the nominal dimensions increased by the permissible plus
36、tolerance or smaller than a prescribed rectangle reduced by the permissible minus tolerance. The sides of the prescribed rectangles shall be parallel to one another and these rectangles shall have a common centre (see Figure 2). The limits of squareness shall also be prescribed by these rectangles.
37、4.2.1 Tolerances The tolerances on nominal dimensions are 4 mm. 4.3 Wire mesh This is a square steel mesh welded at all intersections of approximate dimensions 12,5 mm or 25,0 mm, manufactured from wire of diameter U 0,42 mm. 5 Quality requirements One quality level is considered in this standard. T
38、his is determined by evaluation of the visual faults. There are three different types of pattern faults considered which may occur simultaneously. They are shown in Figure 3 and are: out of square; waviness; bow. Nominal thickness (mm)Tolerances (mm) 6 0,6 7 0,7 8 0,8 9 +1,5 1,0 Figure 2 Determinati

They are shown in Figure 4 and
40、are: out of square; waviness; bow. 5.1 Methods of observation and measurement 5.1.1 Visual faults 5.1.1.1 Spot and linear/extended faults The glass pane to be examined is illuminated in conditions approximating to diffuse daylight and is observed in front of a matt grey screen. Place the pane of gla
41、ss to be examined vertically 3 m in front of and parallel to the screen. Arrange the point of observation 1,5 m from the glass, keeping the direction of observation normal to the glass surface. View the pane of glass and note the presence of visually disturbing faults. a) Spot faults Measure the dim
42、ensions of these faults with a micrometer with graduations in tenths of a millimetre. Note the number, dimensions and concentration of the spot faults. b) Linear/extended faults Note the number of these faults. 5.1.1.2 Pattern faults A reference, e.g. line or straight edge, is placed on the glass as
43、 shown in Figure 3, The deviation, x, of the pattern in relation to the reference is measured. 5.1.1.3 Wire faults A reference, e.g. line or straight edge, is placed parallel to the direction of the wires. The deviation, y, of the wire in relation to this reference is measured (see Figure 4). Any pe
44、netration of the glass surface by the wire is noted. Any breaks in the wire are noted. 5.2 Acceptance levels 5.2.1 Spot faults a) Spherical and quasi-spherical spot faults. If the larger dimension is k 2,0 mm, they are accepted without restriction. If the larger dimension is 2,0 mm and k 5,0 mm, the
45、y are acceptable up to any 2 in any 1 m 1 m area. They are not acceptable if the larger dimension is 5,0 mm. b) Elongated spot faults of width k 2,0 mm. If their length is k 4,0 mm, they are acceptable without restriction. If their length is 4,0 mm and k 25,0 mm, they are acceptable if the sum of th
46、e lengths is k100 mm in any 1 m 1 m area. They are not acceptable if their length is 25,0 mm. c) Elongated spot faults of width 2,0 mm. If the larger dimension is k 8,0 mm, they are acceptable up to 2 in any 1 m 1 m area. They are not acceptable if the larger dimension is 8,0 mm. 5.2.2 Linear/extend
47、ed faults The allowable number of faults is an average of 0,05 faults in every 20 m2 of glass related to at least 20 tonnes. 5.2.3 Pattern faults The deviation of the pattern, x, (see Figure 3) shall not exceed 12 mm per metre. 5.2.4 Wire faults The deviation, y, (see Figure 4) shall not exceed 15 m
48、m per metre. NOTEThe deformation of the wires of each square of the mesh is not considered. No penetration of the surface is acceptable. A break in the wire is acceptable only if it does not affect vision in a disturbing manner under the conditions of observation described in 5.1.1. 6 Designation Wi
49、red patterned glass in compliance with this standard shall be designated respectively by: type (mesh size); tint (manufacturers reference) or clear; pattern (manufacturers reference); nominal thickness in millimetres; nominal length, H, and width, B, in millimetres; reference to this part of this standard. Example Wired patterned glass (12,5 mm); pattern reference “PATTERN”; clear; thickness 7 mm; length 3,30 m; width 1,80 m; intended for use in building, is designated as follows:
