The work of preparing Internatio
7、nal Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO
8、, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Par

28、ument. This is determined by evaluation of 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 wi
29、re 2 mm, or in contact with the wire. There are three different types of deviation of the wire considered, which may occur simultaneously. They are shown in Figure 3 and are out of square, waviness, and bow. 5.2 Methods of observation and measurement 5.2.1 Optical faults The glass pane to be examine
30、d is placed 1 m from a bank of strip lights. The observer stands 1 m away from the glass pane. The strip lights are viewed through the glass and any disrobing distortions within the glass pane are noted. 5.2.2 Visual faults 5.2.2.1 Spot and linear/extended faults The glass pane to be examined is ill
31、uminated in conditions approximating to diffuse daylight and is observed in front of a matt black screen (reflection coefficient between 0,2 and 0,4)4 ISO 2017 All rights reserved ISO 16293-3:2017(E) Place the pane of glass to be examined vertically in front of the screen and parallel to it. Arrange
32、 the point of observation 2 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 faults Measure the dimensions of these faults with a micrometre with graduations in tenths of a millime
33、tre. Note the number, dimensions and concentration of the spot faults together with their relationship to the wire. b) Linear/extended faults Note the number of these faults. 5.2.2.2 Wire faults A reference, e.g. line or straight edge, is placed parallel to the direction of the wires. The deviation
34、of the wire in relation to this reference edge is measured (see Figures 3 to 5). x y z Out of square Waviness Bow NOTE The scale of these drawings is exaggerated to be explicit.
