This is determined by evaluation of the visual faults. There are three different types of pattern faults considered which may occur simultaneously.
30、They are shown in Figure 2 and are as follows: out of square; waviness; bow.4 ISO 2016 All rights reserved ISO 16293-5:2016(E) 5.2 Methods of observation and measurement 5.2.1 Visual faults 5.2.1.1 Spot and linear/extended faults The glass pane to be examined is illuminated in conditions approximati
31、ng to diffuse daylight and is observed in front of a matt grey screen. Place the pane of glass to 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
32、of glass, and note the presence of 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 faul
33、ts. 5.2.1.2 Pattern faults A reference, e.g. line or straight edge, is placed on the glass as shown in Figure 2. The deviations, u, v or w of the pattern in relation to this reference are measured. u v w Figure 2 Representations of the type of pattern faults NOTE 1 The scale of these drawings is exa

The deviations, v and w, (see Figure 2) sh
39、all not exceed 12 mm for the waviness and bow, respectively. 5.3.4 E dge defects for final cut sizes The limitations on entrant and emergent faults and bevel are given in Table 8.
