21、d pattern faults) for patterned glass as defined in EN 572-1, for use in building. This Part of this standard applies only to patterned glass supplied in rectangular panes and in stock sizes. EN 572-8 gives information on patterned glass in sizes other than those covered by this Part. 2 Normative re

22、ferences This 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 o

23、f these publications 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 (including amendments). EN 572-1:2004, Glass in building Basic soda lime silicate glass products Part 1: Defini

24、tions and general physical and mechanical properties. 3 Terms and definitions For the purposes of this European Standard, the terms 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

25、 in Figure 1 Figure 1 Relationship between length, width and direction of draw Key 1 direction of draw 3.2 stock sizes glass delivered in the following sizes: Nominal length H: 2 100 mm to 4 500 mm Nominal width B: 1 260 mm to 2 520 mm SANS 50572-5:2006This s tandard may only be used and printed by

26、approved subscription and freemailing clients of the SABS .EN 572-5:2004 (E) 5 NOTE The maximum stock sizes available depend on the manufacturer and the pattern. 3.3 visual faults faults, which alter the visual quality of the glass. They include spot faults, linear/extended faults and pattern faults

27、 3.4 spherical or quasi-spherical spot faults spot faults whose larger dimension is less than or equal to twice the smaller dimension 3.5 elongated spot faults spot faults whose larger dimension is more than twice the smaller dimension 3.6 linear/extended faults faults, which can be on or in the gla

28、ss, in the form of deposits, 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 4 Dimensional requirements 4.1 Thickness 4.1.1 General Th

29、e actual thickness shall be the average of four measurements, taken to the nearest 0,01 mm, 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

30、patterned glass is a function of the pattern as well as the thickness. 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.

32、 pane shall not be larger than a prescribed rectangle resulting from the nominal dimensions increased by the permissible plus tolerance, t, or smaller than a prescribed rectangle reduced by the permissible minus tolerance, t. The sides of the prescribed rectangles shall be parallel to one another an

33、d these rectangles shall have a common centre (see Figure 2). The limits of squareness shall also be prescribed by these rectangles. 4.2.2 Tolerances The tolerances, t, (see Figure 2) on the nominal dimensions length, H, and width, B, are dependant on the thickness of the glass and are shown in Tabl

35、. This is determined by evaluation of the visual faults. SANS 50572-5:2006This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .EN 572-5:2004 (E) 7 There are three different types of pattern faults considered which may occur simultaneously. They ar

36、e shown in Figure 3 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 in conditions approximating to diffuse daylight and is observed in front of a matt grey scree

37、n. 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 surface. View the pane of glass, and note the presence of visually disturbing faults. a) Sp

38、ot 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 the number of these faults. 5.2.1.2 Pattern faults A reference, e.g. line or straight edge,

39、is placed on the glass as shown in Figure 3. The deviation, x, of the pattern in relation to this reference is measured. Figure 3 Representations of the types of pattern faults 5.3 Acceptance levels 5.3.1 Spot faults a) Spherical and quasi-spherical spot faults. If the larger dimension is 2,0 mm, th

40、ey are acceptable with 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. SANS 50572-5:2006This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .EN 572-5:2004 (E) 8 They are not acceptable if

41、 the larger dimension is 5,0 mm. b) Elongated spot faults of width 2,0 mm. If their length is 4,0 mm, 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. They are not acceptable if the length is

42、25,0 mm. c) Elongated spot faults of width 2,0 mm. If the larger dimension is 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. 5.3.2 Linear/extended faults The number of allowable faults is an average of 0,05 faults in 20 m2of glass

43、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. 6 Designation Patterned glass in compliance with this standard shall be designated respectively by: type; tint (manufacturers reference) or clear; pattern (manufactur

44、ers reference); nominal thickness in mm; nominal length, H, and width, B, in mm; reference to this Part of this standard.
