This European Standard applies only to polished wired glass supplied in rectangula
22、r panes and in stock sizes. EN 572-8 gives information on polished 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 and are indispensable for its application.

This is determined by evaluation of
33、 the optical and visual faults. Many spot faults are associated with the wire, due to the incorporation of the wire into the glass. Spot faults can thus be distinguished by their relationship with the wire: distance from the wire 2 mm; distance from the wire 2 mm, or in contact with the wire. There
34、are three different types of deviation of the wire considered, which may occur simultaneously. They are shown in Figure 2 and are classified as: a) out of square; b) waviness; c) bow. DIN EN 572-3:2012-11EN 572-3:2012 (E) 7 5.2 Methods of observation and measurement 5.2.1 Optical faults The glass pa
35、ne to be examined is placed 1 m from a bank of strip lights. The observer stands 2 m away from the glass pane. The strip lights are viewed through the glass and any disturbing distortions within the glass pane noted. 5.2.2 Visual faults 5.2.2.1 Spot faults Measure the dimensions of these faults with
36、 a micrometer with graduations in tenths of a millimetre. Note the number, dimensions and concentration of the spot faults together with their relationship to the wire. 5.2.2.2 Linear/extended faults The glass pane to be examined is illuminated in conditions approximating to diffuse daylight and is
37、observed in front of a matt black screen (reflection coefficient between 0,2 and 0,4). Place the pane of glass to be examined vertically in front of the screen and parallel to it. Arrange the point of observation 2 m from the glass, keeping the direction of observation normal to the glass surface. V
38、iew the pane of glass, and note the presence of visually disturbing faults. 5.2.2.3 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 edge is measured (see Figure 2). Any penetration of t
39、he glass surface by the wire is noted. Any breaks in the wire are noted. 5.3 Acceptance levels 5.3.1 Optical faults The observer should not see any disturbing distortions within the glass pane. 5.3.2 Visual faults 5.3.2.1 Spot faults Spot faults are categorised and found to be acceptable or not acce
40、ptable as follows: a) Spherical and quasi-spherical spot faults situated in contact with the wire or 2 mm from the wire: 1) if the larger dimension is 2,0 mm, they are acceptable without restriction; 2) if the larger dimension is 2,0 mm and 4,0 mm, they are acceptable up to 0,5 per m; 3) they are no
41、t acceptable if the larger dimension is 4,0 mm. b) Spherical or quasi-spherical spot faults situated 2,0 mm from the wire: DIN EN 572-3:2012-11EN 572-3:2012 (E) 8 1) if the larger dimension is 1,0 mm, they are acceptable without restriction. 2) if the larger dimension is 1,0 mm and 4,0 mm, they are
42、acceptable up to 0,5 per m. 3) they are not acceptable if the larger dimension is 4,0 mm. c) Elongated spot faults of width 1,0 mm: 1) if their length is 1,0 mm, they are acceptable without restriction; 2) if their length is 1,0 mm, and 5,0 mm, they are acceptable if their number is 10 per m; 3) if
43、their length is 5,0 mm and 10,0 mm, they are acceptable if their number is 3 per m; 4) if their length is 10,0 mm and 15,0 mm, they are acceptable if their number is 2 per m; 5) they are not acceptable if their length is 15,0 mm. d) Elongated spot faults of width 1,0 mm: 1) if the larger dimension i
44、s 4,0 mm, they are acceptable up to 0,5 per m; 2) they are not acceptable if the larger dimension is 4,0 mm. 5.3.2.2 Linear/extended faults The allowable number of faults is an average of 0,05 faults in every 20 m of glass, related to at least 20 tonnes. 5.3.2.3 Wire faults The deviation, y, (see Fi
45、gure 2) shall not exceed 15 mm per metre. NOTE 1 The deformation of the wires of each square of the mesh is not considered. No penetration of the surface is acceptable. Breaks in the wire are not acceptable. a) Out of square b) Waviness c) BowNOTE 2 The scale of these drawings has been exaggerated i
