This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2016, and conflicting national standards shall be withdrawn at the latest by July 2016. Attention is drawn to the possibilit

20、y 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 identifying any or all such patent rights. This part of the standard is published to allow the test methodology to be used. As stated in the scope, at the present ti

21、me, the test procedure does not specifically address the durability of the coatings self-cleaning functionality. Work is on-going to develop applicable testing. EN 1096, Glass in building Coated glass, is composed of the following parts: Part 1: Definitions and classification; Part 2: Requirements a

BS EN 1096-5:2016EN 1096-5:2016 (E) 5 1 Scope This European Standard defines a test method to establish the self-cleaning performances

25、for coatings on glass which utilize sun, rain or a combination of sun and rain to enhance the cleanliness of the glass. The European Standard applies to class A coated glass as defined in EN 1096-1 and EN 1096-2 for use in outdoor building applications. The test is designed to be applicable for coat

26、ings on glass which use hydrophilic or photocatalytic active functionalities to enhance the cleanliness of the glass. The test procedure does not specifically address the durability of the coatings self-cleaning functionality. 2 Normative references The following referenced documents, in whole or in

36、al Haze variation between initial cleaning stage and end of cycle 2 5 Principle of the test Standardized glass samples shall be submitted to a spray of a standardized dirt mixture, followed by a simulation of natural weathering action by applying UV irradiation (to simulate sun) and water spray (to

37、simulate rain). This cycle shall be repeated twice to ensure better stability of results. BS EN 1096-5:2016EN 1096-5:2016 (E) 7 The haze shall be measured at initial preparation (after cleaning) and final stage (at the end of the second cycle). The evaluation criteria shall be the haze variation (H)

38、 between the sample after initial preparation (Hinitial) and the sample at the final stage of the test (Hfinal), see Formula (1). = final initialHH H (1) NOTE The incident light on glass samples with dirt deposit is diffused scattered and the effect in transmission is seen as reduction of contrast o

39、f objects observed through the glass. It is strongly recommended to measure haze at each step of the test (as explained in Clause 10) in order to check that there is no deviation of the test. The test and all handling of the product to be tested shall be performed in a clean environment, i.e. exempt

40、 from any source of contamination (organics, silicones, dust) which could modify the surface, affect the functionality, the test conditions or the haze measurements. An example of contamination checking procedure is given in Annex C. 6 Instrumentation 6.1 UVA-Illumination chamber A UV illumination c

41、hamber1)shall be equipped with UVA-340 lamps, such as described in EN ISO 4892-3:2013, Table 1 (“type I” lamps). A closed chamber is recommended. The irradiation power shall be set to 0,68 Wm2nm1at 340 nm on the surface of the samples, which is the maximal irradiance of solar light according to CIE

42、85 Table 4. The irradiation level shall be maintained constant and uniformly distributed such as to ensure a same level of irradiation on all the samples. NOTE The irradiation level can be monitored with a radiometer. The intensity of the lamp can be controlled continuously and adjusted to balance a

43、ging of the lamps. Relative Humidity (RH) shall be maintained between 15 % and 50 % inside the chamber during the irradiation period. The air temperature in the illumination chamber shall remain between 25C and 40C. The UVA cabinet shall be placed in a well-ventilated area and its vents shall be ful

44、ly opened, to ensure that the temperature inside the cabinet remains in the indicated values. The temperature and RH shall be monitored and given in the test report. The cabinet shall be clean and exempt of any contamination source, especially silicone source, see Annex C. 6.2 Sample support For the

45、 spraying steps, the sample shall be installed on a support, with an inclination of 10 from vertical. The description of the support is given in Annex A. 1) Equipment UV2000 or UVCon from Atlas or QUV from QPannel have been used during the Round Robin tests and found to be suitable. This equipment i
