EN 1036-1:2007 (E) 5 1 Scope This European Standard specifies minimum quality requirements (in respect of optical, visual and edge faults) and durability tests for 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 Standard 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 used 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 apply to framing, fixing or other support systems. NOTE
Useful advice on these items is contained in the informative Annex B. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 410, Glass in building — Determination of luminous and solar characteristics of glazing EN 572-2, Glass in building — Basic soda lime silicate glass products — Part 2: Float glass EN ISO 2409, Paints and varnishes - Cross-cut test (ISO 2409:2007) EN ISO 9227, Corrosion tests in artificial atmospheres — Salt spray tests (ISO 9227:2006) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 float glass flat, transparent, clear or tinted soda-lime silicate glass having parallel and polished faces obtained by continuous casting and flotation on a metal bath (see EN 572-1 and EN 572-2) 3.2 mirror from silver-coated float glass flat annealed clear or tinted float glass whose rear surface has been coated with a protected reflective silver deposit 3.3 copper-free mirror from silver-coated float glass flat annealed clear or tinted float glass whose rear surface has been coated with a protected reflective silver deposit without use of copper



EN 1036-1:2007 (E) 6 3.4 stock/standard sizes panes of mirrors from silver-coated float glass supplied with as-cut edges which are intended for further processing NOTE For dimensions of jumbo sizes and split sizes see EN 572-2. 3.5 as-cut finished sizes finished panes of mirrors from silver-coated float glass cut from stock/standard sizes NOTE They can be subject to further processing, e.g. edge working, drilling, face decoration. 3.6 optical faults faults directly associated with the distortion of the reflected image 3.7 glass appearance faults faults which alter the visual quality of the mirror from silver-coated float glass. 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 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 the reflective silver layer which will alter the appearance of the silvered glass. 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 sometimes cover the whole reflective surface 3.14 colour spots alteration of the reflective coating in the form of small, generally coloured spots 3.15 edge deterioration discolouration of the reflective silver at the edge of the silvered glass



EN 1036-1:2007 (E) 7 3.16 protective coating(s) faults faults where the metallic layer is exposed. They can be scratches or loss of adhesion of the protective coating(s) 3.17 edge faults faults that affect the as-cut edge of the silvered glass. They can include entrant/emergent faults, shelling, corners on/off and vents 3.18 pack area total surface area of the contents of a pack 3.19 cluster group of not less than 3 spot faults, separated by not more than 50 mm 3.20 halo distortion zone around a spot fault (see 3.8) 4 Materials 4.1 Glass products 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/m² 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 measurements, 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.



EN 1036-1:2007 (E) 8 Table 1 — Thickness and tolerances Nominal thickness (mm) Thickness tolerances (mm) 2 3 4 5 6 8 10 ± 0,2 ± 0,2 ± 0,2 ± 0,2 ± 0,2 ± 0,3 ± 0,3
5.2 Length, width and squareness 5.2.1 Stock/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 dimensions 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 dimensions 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 greater 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 dimensions 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 applied to standard or stock sizes or in standards for other types of glass products.



EN 1036-1:2007 (E) 9 6 Reflection characteristics of silvered mirrors 6.1 Measurement Measurement of reflectance shall be undertaken in accordance with the principle of EN 410, but with the angle of incidence of the light within 8° of normal. Illuminant will be D65 and observer 2. 6.2 Silvered mirrors made from clear float glass The regular luminous coefficient of silvered mirrors made from clear float glass shall be at least: - 86 % for float with a thickness between 2 mm and 6 mm; - 83 % for float with a thickness of 8 mm and 10 mm. 6.3 Silvered mirrors made from tinted float glass Silvered mirrors made from tinted float glass have a reflectance lower than those made from clear glass. 7 Quality requirements 7.1 General The quality of a silvered mirror can be affected by faults, which alter the appearance of the image of reflected objects. Such alteration of the image can result from optical faults, faults in the glass and faults in the reflective coating. 7.2 Quality assessment and inspection methods for silvered mirrors 7.2.1 Glass, reflective coating, edge and protective coating quality 7.2.1.1 Inspection method The silvered mirror shall be observed in a vertical position, with the naked eye and under normal diffused lighting conditions, (natural daylight o
