BS EN 572-6:2012EN 572-6:2012 (E) 4 1 Scope This European Standard specifies dimensional and minimum quality requirements (in respect of optical and visual faults) for wired patterned glass, as defined in EN 572-1:2012, for use in building. This European Standard applies only to

20、wired patterned 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 European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document an

27、onal 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, 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 diame

28、ter of (50 5) mm. NOTE The mechanical resistance of wired patterned glass is a function of the pattern as well as the thickness. BS EN 572-6:2012EN 572-6:2012 (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 toleranc

The limits of squareness are described by devi

30、ation between diagonals. Such limits are given in Table 2.

This is determined by evaluation of the visual faults. There are three different

32、types of pattern faults considered which may occur simultaneously. They are shown in Figure 2 and are a) out of square; b) waviness; c) bow. BS EN 572-6:2012EN 572-6:2012 (E) 7 There are three different types of deviation of the wire considered which may occur simultaneously. They are shown in Figur

33、e 3 and are d) out of square, e) waviness, f) bow. 5.2 Methods of observation and measurement 5.2.1 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 glass to

34、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) Spot faults Measure the dimensio

35、ns 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. 5.2.2 Pattern faults A reference, e.g. line or straight edge, is placed on the glass as shown

36、in Figure 2. The deviation, x, of the pattern in relation to this reference is measured. a) Out of square b) Waviness c) Bow NOTE The scale of these drawings has been exaggerated in order to be explicit about the types of deviation. Figure 2 Representations of the type of pattern faults 5.2.3 Wire f

37、aults 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 3). BS EN 572-6:2012EN 572-6:2012 (E) 8 Any penetration of the glass surface by the wire is noted. Any breaks in the wi

38、re 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. Figure 3 Representations of the types of wire faults 5.3 Acceptance levels 5.3.1 Spot faults Spot faults are categorized and found to be accept

39、able or not acceptable as follows: a) Spherical and quasi-spherical spot faults: 1) If the larger dimension is 2,0 mm, they are acceptable without restriction; 2) 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;. 3) They are not acceptable if the larger

40、dimension is 5,0 mm. b) Elongated spot faults of width 2,0 mm: 1) If their length is 4,0 mm, they are acceptable without restriction; 2) 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; 3) They are not acceptable if the length is 25,

41、0 mm. c) Elongated spot faults of width 2,0 mm: 1) If the larger dimension is 8,0 mm, they are acceptable up to 2 in any 1 m 1 m area; 2) 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 m of gla

42、ss related to at least 20 tonnes. BS EN 572-6:2012EN 572-6:2012 (E) 9 5.3.3 Pattern faults The deviation of the pattern, x, (see Figure 2) shall not exceed 12 mm per metre. 5.3.4 Wire faults The deviation, y, (see Figure 3) shall not exceed 15 mm per metre. NOTE The deformation of the wires of each

43、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 5.2.1. 6 Designation Wired patterned glass in compliance with this European S
