DIN EN 572-5:2012-11EN 572-5:2012 (E) 4 1 Scope This European Standard specifies dimensional and minimum quality
21、 requirements (in respect of visual and pattern faults) for patterned glass as defined in EN 572-1:2012, for use in building. This European 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 tho
22、se covered by this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the re

28、n 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, 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
29、 diameter of (50 5) mm. NOTE The mechanical resistance of 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.

There are three different types of pattern faults considered which may occur simultaneously. They are shown in Figure 2 and ar
34、e a) out of square, b) waviness, c) 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 be examine
35、d 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 the following visually disturbing faults. a) Spot faults: Measure the dim
36、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. 5.2.2 Pattern faults A reference, e.g. line or straight edge, is placed on the glass as
37、shown in Figure 2. The deviation, x, of the pattern in relation to this reference is measured. DIN EN 572-5:2012-11EN 572-5:2012 (E) 8 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 2 Representatio
38、ns of the types of pattern faults 5.3 Acceptance levels 5.3.1 Spot faults Spot faults are categorized and found to be acceptable or not acceptable as follows: a) Spherical and quasi-spherical spot faults: 1) If the larger dimension is 2,0 mm, they are acceptable with restriction; 2) If the larger di
39、mension 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 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
40、 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 25,0 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 dime
41、nsion 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 related to at least 20 t. 5.3.3 Pattern faults The deviation of the pattern, x, (see Figure 2) shall not exceed 12 mm per metre.
