DIN EN 1096-3:2012-04 EN 1096-3:2012 (E) 4 1 Scope This European Standard
23、 specifies requirements and a test method related to resistance to solar radiation for coated glass for use in buildings. This test is aimed at evaluating if the exposure to solar radiation over an extended period of time produces any appreciable change in light transmittance and solar transmittance
24、 of the coated glass as well as a reduction of the infrared reflectance in the case of low emissivity coatings. This European Standard applies to Class C and D coatings as defined in EN 1096-1 and used in insulating glass units. 2 Normative references The following referenced documents are indispens
25、able for the application of this document. For dated references, only the edition cited applies.

29、relate to the characteristic resistance to solar radiation. DIN EN 1096-3:2012-04 EN 1096-3:2012 (E) 5 Table 1 Requirements Test piece Visual inspection Spectrophotometric measurements Exposed test specimens No additional defects on the coating are seen as compared to the unexposed double glass test
30、 specimens No requirements Exposed single coated glass test piece No requirements The transmittance values at 550 nm and 900 nm shall differ from the corresponding values of the unexposed single coated glass sample by no more than +/- 0,03 For a glass claimed to have a low emissivity coating, the re
31、flectance at 8 m shall decrease by no more than 0,02. 5 Samples, test pieces and test specimens 5.1 Test pieces 5.1.1 Coated annealed glass A sample of 1000 mm x 500 mm is needed. Two square test pieces of minimum size 250 mm x 250 mm shall be cut from the sample. 5.1.2 Toughened or heat strengthene
32、d coated glass For the thermally treated coated glass, defined in EN 1096-1:2012, 3.1.8 to 3.1.11, as the test pieces cannot be cut from test samples, a special procedure has to be employed to obtain the test pieces (see annex A). 5.1.3 Coated toughened or heat strengthened glass Use coated annealed
33、 glass samples for testing this type of coated glass. 5.2 Preparation of test specimens Two insulating glass units shall be manufactured as test specimens. The insulating glass units shall consist of one of the test pieces, 12 mm airspace and a piece of 4 mm clear float glass (in compliance with EN
34、572-1 and EN 572-2). The dew point of the test specimens shall not be higher than - 25C, when measured at (23 5) C, according to EN 1279-2:2002, Annex A, or equivalent. The dew point is ensured when the insulating glass unit is manufactured in accordance with the EN 1279 series. The edge area of the
35、 test specimens shall be covered with a reflecting aluminium foil (40 5) mm wide as a means of protection for the sealant components. 6 Initial evaluation of the test pieces The external surfaces of the test pieces shall be cleaned with a soft tissue using demineralised water, having a conductivity
36、lower than 30 S. Drying shall also be done with a soft tissue. If necessary this cleaning procedure can be repeated. DIN EN 1096-3:2012-04 EN 1096-3:2012 (E) 6 The test pieces shall be subjected to a visual inspection under an artificial sky according to EN 1096-1 at a distance of 600 mm. The examin
37、ation shall be in both transmission and reflection. The test pieces shall be defect free, i.e. no visible scratches or pinholes shall be allowed. 7 Test methods for exposure to simulated solar radiation NOTE Annex B gives criteria to demonstrate equivalence of coatings, i.e. an indication of whether
38、 or not the coated glass needs to be tested. 7.1 Radiation source Radiation sources shall be used which emit radiation with a spectral distribution similar to the spectral solar global distribution as given in EN 410 and with percentages of UVB and UVA as given in Table 2. Such a spectral distributi
39、on can be obtained using different kinds of lamps (examples of test apparatus are given in Annex C). Table 2 Spectral characteristics of the lamps used for the test Radiation Range of wavelength (nm) Percentage of total energy (%) ultraviolet range UVB 280 to 315 1 to 4 ultraviolet range UVA 315 to
40、380 3 to 9 visible and infrared range 380 balance 7.2 Test conditions The total irradiance level measured on the surface of the test pieces (surface facing the test lamps) shall be (900 100) W/m. NOTE Calibrated pyranometers with characteristics as reported in ISO 9060 and with a spectral sensitivit
41、y in the 305 mm to 2800 mm range should be used for the determination of the total irradiance level. Using these detectors, the measured irradiance level on the surface of the test pieces should be (730 80) W/m. The exposure time for the radiation test shall be: (1000 24) h in the case of test appar
42、atus given in C.1; (2000 24) h in the case of test apparatus given in C.2. The test specimen shall be placed with the coating orientated towards the radiation source. When tested, the coating shall be on surface 3. However, when the coating is only to be used on surface 2, then it shall be tested on
43、 surface 2. Figures C.1 a) (planar array) or C.1 b) (circular array) show the arrangement of the test specimens and the reference glass piece. The reference glass piece has a thermocouple placed on its surface facing the test lamps. The temperature of the reference glass piece shall be (56 3) C. DIN
44、 EN 1096-3:2012-04 EN 1096-3:2012 (E) 7 7.3 Reference glass piece An enamelled thermally toughened soda lime silicate safety glass, according to EN 12150-1, shall be used as a reference glass piece. It will be manufactured from of a piece of float glass, up to 10 mm thickness, according to EN 572-1
45、and EN 572-2 with an enamelled black frit on the surface facing the array of lamps. The reference glass piece shall have the following properties: dimensions not less than 250 mm; solar direct absorption e 0,92 determined according to EN 410 with radiation of normal incidence onto the surface of the
46、 reference glass piece facing the test lamps; normal emissivity n 0,84 at (23 5) C of both outer surfaces of the reference glass piece, measured according to EN 12898 with radiation of nearly normal incidence; thermal conductance between the two outer surfaces 100 W/(m2K). 7.4 Test procedure The tes
47、t procedure shall include the following steps: initial visual inspection of the two test pieces according to Clause 6; checking for the appearance of humidity between the panes; exposure of one test piece under simulated solar radiation, and storage of the second test piece in a dark room at a tempe
48、rature of (23 5) C; final visual inspection of the exposed and unexposed test pieces according to 8.1; checking for the appearance of humidity between the panes; opening of both test pieces and preparation of a test portion according to 8.2; spectrophotometric measurements. 8 Final evaluation of exposed test pieces 8.1 Visual inspection The exposed test specimens shall
