plate gauge type with a diameter o f 50 mm ± mm NOTE 4.1.2 The mechanical resistance of wired patterned glass is a function of the pattern as well as the thickness Tolerances All four measurements, rounded to the nearest 0,1 mm shall not vary from the nominal thickness by more than the tolerances shown in Table Table — Tolerance on nominal thickness Dimensions in millimetres Nominal thickness

25,0 mm, or a diamond mesh of approximate dimensions 19 mm The mesh is welded at all intersections and manu factured from wire o f diameter ≥0,42 mm Quality requirements 5.1 General One quality level is considered in this document This is determined by evaluation o f the visual faults There are three di fferent types o f pattern faults considered which may occur simultaneously They are shown in Figure and are: — out of square, — waviness, and — bow There are three di fferent types o f deviation o f the wire considered which may occur simultaneously They are shown in Figure and are: — out of square, — waviness, and — bow 5.2 Methods of observation and measurement 5.2.1 5.2.1.1 Visual faults Spot and linear/extended faults The glass pane to be examined is illuminated in conditions approximating to di ffuse daylight and is observed in front o f a matt grey screen Place the pane o f glass to be examined vertically m in front o f and 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 o f glass, and note the presence o f visually disturbing faults a) Spot faults Measure the dimensions of these faults with a micrometre 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, is placed on the glass as shown in Figure The deviations, u , v or w of the pattern in relation to this reference are measured I n tern ati o n al Org an i z ati o n fo r S tan d ard i z ati o n w v ISO 62 93 -4: 01 6(E) u Out of square NOTE NOTE Waviness The scale of these drawings is exaggerated to be explicit

direction of the wires The deviations, x, y, or z, of the wire in relation to this reference are measured (see Figure 3) Any penetration o f the glass sur face by the wire is noted z y Any breaks in
