BS EN ISO 12543-6:2011 EN ISO 12543-6:2011 (E) ISO 201 iiiForeword ISO (the International Organization for Standardization) is a w
17、orldwide federation of national standards bodies (ISO member bodies). The work of preparing International 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
18、on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafte
19、d in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Stand
20、ard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12543-6 was prepared

NOTE Special attention is paid t
24、o acceptability criteria in the vision area. This part of ISO 12543 is applicable to finished sizes at the time of supply. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、 after manufacture 3.12 edge area perimeter of the pane, which is generally contained within the glazing system NOTE For pane sizes that are less than 5 m2, the width of the edge area as given in Figure 1 is 15 mm. The width of the edge area is increased to 20 mm for pane sizes that are greater than

32、inated glass is put in a vertical position, in front of and parallel to a matt grey screen, and is lit by diffuse daylight or equivalent. The laminated glass is visually inspected perpendicularly at a distance of 2 m from the glass, with the matt screen on the other side of the glass. Any visible de
33、fects that are disturbing shall be marked. 5 Defects in the edge area for framed edges When inspected according to the test method given in Clause 4 , defects which do not exceed 5 mm in diameter or 5 % to the edge area are permitted. 6 Vents Vents are not permitted. 7 Creases and streaks These are
34、not allowed in the visual area. 2 BS EN ISO 12543-6:2011 EN ISO 12543-6:2011 (E)4 ISO 20128 Defects in the vision area 8.1 Spot defects in the vision area When inspected according to the test method given in Clause 4 , the admissibility of spot defects depends on the following: size of the defect; f
35、requency of the defect; size of the pane; number of panes as components of a laminated glass. The number of permissible defects in a pane shall be in accordance with Table 1. Defects less than 0,5 mm shall not be considered. Defects greater than 3 mm shall not be permitted. NOTE Admissibility of spo
