Measurement shall be by means of an instrument of the plate gauge type with a diameter of 50 mm 5 mm.NOTEThe mechanical resistance of wired patterned glass is a function of the pattern as well as the thickness.4.1.2TolerancesThe actual thickness rounded to the nearest 0,1 mm shall not v

The sides of the prescribed rectangles shall be parallel to one another and these rectangles s

33、Wire meshThis 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.5Quality requirements5.1GeneralOne quality level is considered in this standard. This is determined by evaluation of the visual faults.There are t

34、hree different types of pattern faults considered which may occur simultaneously. They are shown inFigure 3 and are: out of square; waviness; bow.There are three different types of deviation of the wire considered which may occur simultaneously. They are shown in Figure 4 and are: out of square; wav

35、iness; bow.5.2 Methods of observation and measurement5.2.1Visual faults5.2.1.1 Spot and linear/extended faultsThe 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 examined vertically

36、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 faultsMeasure the dimensions of these faults with a

37、micrometer with graduations in tenths of a millimetre. Note the number, dimensions and concentration of the spot faults.b)Linear/extended faultsNote the number of these faults.5.2.1.2Pattern faultsA reference, e.g. line or straight edge, is placed on the glass as shown in Figure 3. The deviation, x,

38、 of the pattern in relation to this reference is measured.Out of squareWavinessBowNOTEThe scale of these drawings is exaggerated to be explicit.Figure 3 Representations of the type of pattern faults5.2.1.3Wire faultsA reference, e.g. line or straight edge, is placed parallel to the direction of the

39、wires. The deviation, y, of the wire in relation to this reference is measured (see Figure 4).Any penetration of the glass surface by the wire is noted. Any breaks in the wire are noted.Out of squareWavinessBowNOTEThe scale of these drawings is exaggerated to be explicit.Figure 4 Representations of

They are not acceptable i

41、f 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 any1 m 1 m area.They are not acceptable if the length is 25,0

42、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.5.3.2Linear/extended faultsThe allowable number of faults is an average of 0,05 faults in 20 m2 of glass related t

43、o at least 20 tonnes.5.3.3Pattern faultsThe deviation of the pattern, x, (see Figure 3) shall not exceed 12 mm per metre.5.3.4Wire faultsThe deviation, y, (see Figure 4) shall not exceed 15 mm per metre.NOTEThe deformation of the wires of each square of the mesh is not considered. No penetration of

44、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 5.2.1.1.6DesignationWired patterned glass in compliance with this standard shall be designated respectively by: type (mesh size); tint
