This European Standard shall be given the status of a national standard, either by publication of an identic
22、al text or by endorsement, at the latest by December 2004, and conflicting national standards shall be withdrawn at the latest by December 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential req
23、uirements of EU Directive(s).

EN 572-6:2004 (E) 4 1 Scope This Part of this European Standard specifies dimensional and minimum quality requirements (in respect of optical and visual faults) for float glass, as defined in EN 572-1, for use in building. This Part of this standard applies only to wired patterned
27、glass supplied in rectangular panes and in stock sizes. EN 572-8 gives information on patterned wired glass in sizes other than those covered by this Part. 2 Normative references This European Standard incorporates by dated or undated references, provisions from other publications. These normative r
28、eferences 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 publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references
29、 the latest edition of the publication referred to applies (including amendments). EN 572-1:2004, Glass in building Basic soda lime silicate glass products Part 1: Definitions and general physical and mechanical properties. 3 Terms and definitions For the purposes of this European Standard, the term
30、s and definitions given in EN 572-1:2004 and the following apply. 3.1 length, H, and width, B defined with reference to the direction of draw of the glass ribbon as shown in Figure 1 Figure 1 Relationship between length, width and direction of draw Key 1 direction of draw 3.2 stock sizes glass deliv
31、ered in the following sizes: Nominal length H: 1 380 mm to 4 500 mm Nominal width B: 1 500 mm to 2 520 mm EN 572-6:2004 (E) 5 3.3 visual faults 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
32、-spherical spot faults spot faults whose larger dimension is less than or equal to twice the smaller dimension 3.5 elongation spot faults faults whose larger dimension is more than twice the smaller dimension 3.6 linear/extended faults faults, which can be on or in the glass, in the form of deposits
33、, marks or scratches which occupy an extended length or area 3.7 pattern faults deviations of the pattern relative to a reference, e.g. line or straight edge 3.8 deviation of the pattern deviation, x, of the pattern 3.9 wire faults deviations of the wire, penetration of the glass surface by the wire
34、 or break in the wire in the body of the glass 3.9 deviation of the wire deviation, y, of the wire relative to a reference, e.g. line or straight edge 4 Dimensional requirements 4.1 Thickness 4.1.1 General The actual thickness shall be the average of four measurements, taken to the nearest 0,01 mm,
35、each one taken 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. NOTE The mechanical resistance of wired patterned glass is a function of the pattern as well as the thickness. EN 572-6:2
36、004 (E) 6 4.1.2 Tolerances The actual thickness rounded to the nearest 0,1 mm shall not vary from the nominal thickness by more than the tolerances shown in Table 1. Table 1 Tolerances on nominal thickness Nominal thickness (mm)Tolerances (mm) 6 0,6 7 0,7 8 0,8 9 5 , 1 01 + 4.2 Length, width and squ
37、areness 4.2.1 General 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 tolerance or smaller than a prescribed rectangle reduced by the permissible minus to
38、lerance. 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. Figure 2 Determination of length, width and squareness The limits of squareness shal
39、l also be prescribed by these rectangles. 4.2.2 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 0,42 mm. EN 572-6:2004 (E) 7 5 Quality requ
40、irements 5.1 General One quality level is considered in this standard. This 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. There are three
41、 different types of deviation of the wire considered which may occur simultaneously. They are shown in Figure 4 and are: out of square; waviness; bow. 5.2 Methods of observation and measurement 5.2.1 Visual faults 5.2.1.1 Spot and linear/extended faults The glass pane to be examined is illuminated i
42、n conditions approximating to diffuse daylight and is observed in front of a matt grey screen. Place the pane of glass to be examined vertically 3 m in front of the parallel to the screen. Arrange the point of observation 1,5 m from the glass, keeping the direction of observation normal to the glass
43、 surface. View the pane of glass, and note the presence of visually disturbing faults. a) Spot faults Measure the dimensions 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
44、the number of these faults. 5.2.1.2 Pattern faults A reference, e.g. line or straight edge, is placed on the glass as shown in Figure 3. The deviation, x, of the pattern in relation to this reference is measured. EN 572-6:2004 (E) 8 Out of square Waviness Bow NOTE The scale of these drawings is exag
45、gerated to be explicit. Figure 3 Representations of the type of pattern faults 5.2.1.3 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 penetration of the
46、 glass surface by the wire is noted. Any breaks in the wire are noted. Out of square Waviness Bow NOTE The scale of these drawings is exaggerated to be explicit. Figure 4 Representations of the types of wire faults 5.3 Acceptance levels 5.3.1 Spot faults a) Spherical and quasi-spherical spot faults.
47、 If the larger dimension is 2,0 mm, they are acceptable without restriction. If the larger dimension is 2,0 mm and 5,0 mm, they are acceptable up to 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 2,0 mm. If their length is 4,0 mm,
48、they are acceptable without restriction. If their length is 4,0 mm and 25,0 mm, they are acceptable if the sum of the lengths is 100 mm in any 1 m 1 m area. EN 572-6:2004 (E) 9 They are not acceptable if the length is 25,0 mm. c) Elongated spot faults of width 2,0 mm. If the larger dimension is 8,0
49、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. 5.3.2 Linear/extended faults The allowable number of faults is an average of 0,05 faults in 20 m2 of glass related to at least 20 tonnes. 5.3.3 Pattern faults The deviation of the pattern, x, (see Figure 3) shall not exceed 12 mm per metre. 5.3.4 Wire faults The deviation, y, (see Figu
