 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 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, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
For a glass claimed to have a low emissivity coating, the reflectance at 8 µm 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 strengthened 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 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 572-1 and EN 572-2). The dew point of the test specimens shall not be higher than - 25°C, 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 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 lower than 30 µS. Drying shall also be done with a soft tissue. If necessary this cleaning procedure can be repeated. SIST EN 1096-3:2012
