37、provide the quality of a silvered mirror reflection, the mirror shall be manufactured with at least 0,7 g/m 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

38、, 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

39、 nearest 0,1 mm shall not vary from the nominal thickness by more than the tolerances shown in Table 1. BS EN 1036-1:2007EN 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

40、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

41、 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 nomina

42、l 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 dim

43、ensions 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 di

44、agonal 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 fr

45、om that applied to standard or stock sizes or in standards for other types of glass products. BS EN 1036-1:2007EN 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

46、 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; -

47、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,

48、 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 protectiv

49、e 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 or simulated daylight, between 300 lx and 600 lx at the silvered mirror), from a distance of 1 m. The direction of observation is normal, i.e. at right angles, to the silvered mirror. The use of an additional lighting source, e.g. spotlight, is not allowed. 7.2.1.2 Glass fault Glass faults are assessed using the method in 7.2.1.1. The dimension and nu
