23、or mirrors from silvered float glass for internal use in building. This European Standard applies only to mirrors from silvered glass manufactured from flat annealed clear or tinted float glass, 2 mm to 10 mm thickness, and supplied in stock/standard sizes and as-cut finished sizes. This European St
24、andard does not apply to mirrors from silvered glass manufactured from any basic glass other than float glass, any processed glass, i.e. thermally toughened safety glass, heat strengthened glass, chemically strengthened glass and laminated glass, and any bent glass. For mirrors from silvered glass u
25、sed in aggressive and/or constantly high humidity atmospheres, e.g. horse riding halls, swimming pools, medical baths, saunas etc. this European Standard is not applicable. This European Standard is not applicable to reflective glass for external glazing applications. This European Standard does not
26、 apply to framing, fixing or other support systems.

They can be spot and/or linear and/or enlarged area faults 3.8 spot faults nuclei (solid or gaseous inclusions), deposits, crush marks etc. In certain instances spot faults are accompanied by a distortion zone called halo. The nucleus of the spot fault is
34、 measurable 3.9 linear defects scratches, extended spot faults etc. 3.10 brush marks very fine circular scratches that can hardly be seen and are associated with glass cleaning techniques 3.11 scratches any kind of scratches that are not brush marks 3.12 reflective silver coating faults faults in th

They consist of scratches, stain, colour spots and edge deterioration 3.13 stain alteration of the reflective coating characterized by a more or less brownish, yellowish or greyish colouration of zones which can sometim

39、oducts Mirror from silver-coated float glass, according to this European Standard, shall be manufactured from monolithic float glass conforming to EN 572-2. 4.2 Reflective coating In order to provide the quality of a silvered mirror reflection, the mirror shall be manufactured with at least 0,7 g/m
40、of silver. 4.3 Protective coating(s) The reflective coating described in 4.2 shall be protected by a layer of metallic copper or another material and one or more protective coatings e.g. paint, lacquer. 5 Dimensional requirements 5.1 Thickness The actual thickness shall be the average of four measur
41、ements, taken to the nearest 0,01 mm, one taken at the centre of each side. Measurement shall be by means of an instrument of the calliper micrometer type. The actual thickness, rounded to the nearest 0,1 mm shall not vary from the nominal thickness by more than the tolerances shown in Table 1. Lice

43、ck/standard sizes Length, H, and width, B, are defined with reference to the direction of draw of the float glass ribbon as shown in Figure 1. The nominal dimensions for length, H, and width, B, being given, the pane shall not be larger than a prescribed rectangle resulting from the nominal dimensio
44、ns increased by the tolerance, nor smaller than a rectangle defined by their nominal dimensions reduced by the tolerance The sides of the prescribed rectangles shall be parallel to one another and these rectangles shall have a common centre. For stock/standard sizes the tolerances on nominal dimensi
45、ons length, H, and width, B, are 5 mm. The limits of squareness shall also be described by these rectangles (see Figure 2). 5.2.2 As-cut finished sizes For dimensions less than or equal to 2 000 mm, the standard tolerance range is 2 mm, to be stated as 1 mm of the nominal dimension. For dimensions g
46、reater than 2 000 mm, the standard tolerance range is 3 mm to be stated as 1,5 mm of the nominal value. The standard tolerance range to be applied shall be determined by the largest dimension of the pane. The squareness tolerance shall be expressed as the difference in length between the diagonal di
47、mensions of the pane. For plates with both dimensions less than or equal to 2 000 mm the difference shall not exceed 3 mm. For plates with one (or both) dimensions greater than 2 000 mm the difference shall not exceed 4 mm. NOTE The method of determining squareness tolerance is different from that a
