2、overs Definitions, requirements and test methods and EN 1036-2 covers Evaluation of conformity. b) In the normative references (clause 2) ISO 5740 has been deleted and replaced by EN 410. c) The terms “copper-free mirror from silver-coated float glass” (3.3) and “scratches” (3.11) have been added. T

3、he term “hairline scratches” has been changed to “brush marks” (3.10). d) In Table 1 “Thickness and tolerances” which has been revised tolerances for nominal thicknesses of 8 mm and 10 mm have been added. e) In clause 6 “Reflection characteristics of silvered mirrors” the reference to ISO 5740 has b

The standard illuminant is to be D65. f) Requirements for the luminous coefficient (6.2) have been divided up into at least 86

5、% for thicknesses between 2 mm and 6 mm and 83 % for thicknesses of 8 mm to 10 mm. g) In the inspection method to be carried out as part of quality assessment (7.2.1.1) the mirror is now to be observed in daylight of between 300 lx and 600 lx (rather than in daylight of no more than 600 lx). h) Tabl

Previous editions DIN 1238: 1983-04 DIN EN 1036: 1999-07 DIN EN 1036 Supplement 1: 2003-06 National Annex NA (informative) National remarks regarding the fixing of mirrors The fixing of mirrors is not specifie

10、d in DIN EN 1036-1:2008. The only information given on this subject is in the informative annex on cleaning and fixing mirrors; this information does not have any prohibitive character, however, which means that other technical rules on the fixing of mirrors can be applied (e.g. Technical Guideline

11、No. 11 of the German Glaziers Guild (Glaserhandwerk) “Glazing work Mounting mirrors” 4threv. ed. 2006). WARNING If mirrors in buildings are used as overhead mirrors or fall protection, for instance, regulatory provisions may apply in addition to DIN EN 1036-1. Since the variety of mirror fixing mate

12、rials used in Germany is so great, some of the information in the informative Annex B is not applicable. Thus, the following remarks which are likewise informative by the German Federal Association of Guilds in Glazing (Bundesinnungsverband des Glaserhandwerkes) have been included here as a National

13、 Annex: Air should be able to circulate between the mirror and the wall or any other mounting surface. To ensure sufficient ventilation, there should be a gap between the mirror and the mounting surface of at least 5 mm for less than 1 m high mirrors, or at least 510 mm for mirrors with a height gre

14、ater than 1 m Technical Guideline No. 11 of the German Glaziers Guild (Glaserhandwerk) “Glazing work Mounting mirrors” 4threv. ed. 2006. It should be noted that pockets of moisture can form if the gap between the mirror and the mounting surface is too small. Sufficient back-ventilation is essential

15、for the mirrors service life. If the mounting materials used (e.g. adhesives, tapes) do not provide the specified gap, a means of applying the mounting materials shall be used that ensures the best possible ventilation (vertical application of adhesives/tapes, use of distance pieces, or selection of

16、 an appropriate mirror). When mounting on closed-porous surfaces, e.g. pieces of furniture, the gap may be smaller if an increased exposure to moisture is not to be expected Technical Guideline No. 11 of the German Glaziers Guild (Glaserhandwerk) “Glazing work Mounting mirrors” 4threv. ed. 2006. To

17、prevent bending and thus distortion - the weight of the mirror should not be supported by the edges. Particularly large mirrors should be hung to avoid distortion through bulging or bending. Smaller mirrors can DIN EN 1036-1:2008-03 4 bear the weight via brackets or racks without any problems Techni
