20、012-04 EN 1096-2:2012 (E) 4 Foreword This document (EN 1096-2:2012) has been prepared by Technical Committee CEN/TC 129 “Glass in building”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or
21、 by endorsement, at the latest by July 2012, and conflicting national standards shall be withdrawn at the latest by July 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for id
22、entifying any or all such patent rights. This document supersedes EN 1096-2:2001. The main changes compared to the previous edition are: reference to the future EN 1096-5, Test method and classification for the Self-cleaning performances of coated glass surfaces; the introduction of a method to deal
23、 with toughenable / heat strengthenable and to be toughened / to be heat strengthened coated glass, see Annex A. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgari

DIN EN 1096-2
25、:2012-04 EN 1096-2:2012 (E) 5 1 Scope This European Standard specifies requirements and test methods related to artificial weathering and abrasion of coatings on glass for use in buildings. These tests are aimed at evaluating the resistance of the coating to attack by simulated natural weathering co
26、nditions as well as to abrasion. This attack can be considered as representative of that which could be found on the external and/or internal face of the glazing. This European Standard applies to Class A, B and S coatings, as described in EN 1096-1. 2 Normative references The following referenced d
27、ocuments 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 characteristi

EN 12898, Glass in building Determination of emissivity 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 1096-1 apply. 4 Requirements The coated glass
29、complying with this European Standard shall respect the requirements related to the different characteristics given in Table 1.

30、stance Annex B - No defect, as defined in EN 1096-1, greater than 3 mm length - Maximum one defect between 2 mm and 3 mm length - Maximum five defects between 1 mm and 2 mm length In addition, no scratches, staining of the coating or clusters of pinholes greater than 1 mm shall be allowed (see EN 10
31、96-1). When compared with the reference test piece, in both reflection and transmission, there shall be no significant colour change. This observation shall be made within 20 sa. The transmittance measured at 550 nm and 900 nm shall differ by no more than 0,03 from the corresponding measured value o
32、n the reference test piece. For a glass claimed to have a low emissivity coating the reflectance at 8 m shall decrease by no more than 0,02. Acid resistance Annex C No requirements Neutral salt spray resistance Annex D - No defect, as defined in EN 1096-1, greater than 3 mm length - Maximum one defe
33、ct between 2 mm and 3 mm length - Maximum five defects between 1 mm and 2 mm length In addition, no scratches, staining of the coating or clusters of pinholes greater than 1 mm shall be allowed (see EN 1096-1). When compared with the reference test piece, in both reflection and transmission, there s
34、hall be no significant colour change. This observation shall be made within 20 sa. Abrasion resistance Annex E No requirement other than to ensure that the abraded area is uniform Total (diffuse plus direct) transmittance measured at 550 nm and 900 nm shall differ by no more than 0,05 from the corre
35、sponding value measured for the reference test piece. aThe time for observation is fixed to 20 s in order to have a reference period which can influence the visual inspection.

36、 300 mm x 300 mm is needed for each test. For the three chemical durability tests, the test pieces are obtained by cutting the sample as shown in Figure 1. The abrasion test is undertaken on a 300 mm x 300 mm test piece. It is recommended that a spare sample be supplied in the event of one sample no
37、t being defect free. Key 1. test pieces 2. reference test piece for visual inspection 3. reference test piece for spectrophotometric measurement Figure 1 Plan for cutting a sample into test pieces 5.1.2 Thermally treated coated glass For the thermally treated coated glass, defined in EN 1096-1:2012,
38、 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). DIN EN 1096-2:2012-04 EN 1096-2:2012 (E) 8 5.1.3 Coated toughened or heat strengthened glass Use coated annealed glass samples for testing this type o
39、f coated glass. 5.2 Storage The test pieces shall be stored inside a room at a temperature of (23 5) C with a relative humidity less than 80 %. Storage shall prevent dust, chemicals or condensation reacting with the test pieces. The test pieces shall not be stored for more than three months before p
40、erforming the test. 5.3 Marking The test pieces shall be marked on the uncoated glass surface. The following information shall be marked: manufacturers coating reference test pieces number 1 to 4 code for test Glasses with coating on both surfaces shall be marked without damaging the coating. The tw
41、o reference test pieces shall be marked as the test pieces plus “ref“. 6 Initial evaluation of test pieces 6.1 Preparation All test pieces shall be cleaned with demineralised water and with a soft tissue. Drying shall also be done with a soft tissue. If necessary this cleaning procedure can be repea
42、ted. 6.2 Visual inspection The test pieces shall be subjected to a visual inspection under an artificial sky in accordance with EN 1096-1. The inspection shall take place in both transmission and reflection. The test pieces shall be observed at a distance of 600 mm. All test pieces shall be defect f
43、ree. No scratches or pinholes shall be observed. If a test piece contains defects it shall be replaced. NOTE The replacement of test pieces is to avoid any misinterpretation of the testing results. 6.3 Spectrophotometric measurements 6.3.1 Coated annealed glass A measurement sample shall be cut from
44、 the centre of the reference test piece. The actual size shall be dependent on the type of equipment being used for the measurements. The transmittance of the measurement sample shall be measured with radiation of normal incidence at the following wavelengths: 550 nm (representative wavelength for l
45、ight and solar transmittance); 900 nm (representative wavelength for solar transmittance). For glass claiming to have a low emissivity coating a measurement of the reflectance shall be made at 8 m using radiation of nearly normal incidence.
