This test is useful for evaluating the UV r
19、esistance of materials such as polymers and protective coatings. The object of this test is to determine the ability of the module to withstand exposure to ultra- violet (UV) radiation from 280 nm to 400 nm. Before conducting this test, light soaking or other pre-conditioning should be performed in
20、accordance with IEC 6121 5 or IEC 61 646. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All normative documents ar
21、e subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

24、 accordance with IEC 61215 or IEC 61646; - I-V characteristics at standard test conditions (STC) in accordance with IEC 60904-1 ; - insulation test in accordance with IEC 61215 or IEC 61646. STD-BSI BS EN bL3LtS-ENGL II778 II624669 0718059 253 Page 4 EN 61345:1998 4 Apparatus The apparatus consists
25、of the items listed below. a) A temperature controlled test chamber or other arrangement with a window or fixtures for a UV light source and the module(s) under test. The chamber shall be capable of maintaining the module temperature at 60 OC i 5 “C and a dry condition. b) A UV light source capable
26、of producing UV radiation with an irradiance uniformity of I15 % over the test plane of the module(s) and capable of providing the necessary total irradiance in the different spectral regions of interest as defined in clause 5 c). The final test report shall indicate which UV light source is used. c
27、) Means for measuring and recording the temperature of the module(s) to an accuracy of I2 OC. The temperature sensors shall be attached to the front or back surface of the module near the middle. If more than one module is tested simultaneously, it will suffice to monitor the temperature of one repr
28、esentative sample. d) A calibrated radiometer capable of measuring the irradiance of the UV light produced by the UV light source at the test plane of the module(s). See annex A for suggested UV light sources. 5 Procedure The test shall be carried out according to the procedure outlined below. a) Us
29、e the calibrated radiometer to measure the irradiance at the proposed module test plane and ensure that, at wavelengths between 280 nm and 400 nm, the test spectral irradiance is never more than 5 times the corresponding standard spectral irradiance specified in the standard AM 1.5 solar irradiance
30、distribution given by table 1 of IEC 60904-3, that there is no appreciable irradiance at wavelengths below 280 nm and that it has a uniformity of f15 ?“O over the test plane. b) Mount the module in the test plane at the location selected in a) with the front side normal to the UV irradiance beam. c)
31、 While maintaining the module temperature within the prescribed range, subject the module(s) to a minimum irradiance of - 7,5 kWh.m-2 in the wavelength range between 280 nm and 320 nm, and - 15 kWh.m-2 in the wavelength range between 320 nm and 400 nm. d) Reorient the module so that the back side is
32、 normal to the UV irradiance beam. e) Repeat step c) for 10 Ye of the time at the irradiation levels that were performed on the front side. 6 Final measurements Repeat the following tests: - visual inspection in accordance with IEC 61215 or IEC 61646; - I-V characteristics at STC in accordance with
33、IEC 60904-1; - insulation test in accordance with IEC 61215 or IEC 61646. STD-BSI BS EN bL345-ENGL 1998 Lb24669 07L80b0 T75 m Page 6 EN 61345:1998 7 Requirements The photovoltaic modules tested shall fulfill the requirements stated below. - No evidence of major visual defects, as defined in IEC 6121
34、5 or IEC 61646. - The degradation of maximum power output at STC shall not exceed 5 % of the value measured before the test. For thin-film modules, the maximum output power at STC shall exceed the manufacturers minimum power rating for this module type. - Insulation resistance shall meet the same re
35、quirements as for the initial measurements, as defined in IEC 61215 or IEC 61646. Annex A (informative) Suggested UV light sources Selection of a UV light source is based on its ability to meet the spectral requirements of this standard. The following UV light sources can be able to meet these requi
36、rements when properly mounted and/or filtered. A.l QUV-A and QUV-B fluorescent UV lamps, or similar QUV-B lamps have a spectral range from 280 nm to 315 nm. The only drawback with this light source is the fact that almost all of the irradiance will be at the high energy end of the specified irradian
37、ce range. A combination of QUV-B and QUV-A fluorescent lamps may be used to provide the required irradiation in the specified ranges. A.2 Filtered xenon The spectral irradiance of a filtered xenon lamp in the UV-visible range most closely resembles the spectrum of natural sunlight, especially in the
38、 wavelengths from 280 nm to 320 nm. Because xenon reproduces all of the solar spectrum, it has more energy in the wavelength bracket ranging from 320 nm to 400 nm than the test specifies. To achieve a total irradiation of 75 kWh.m-2 between 280 nm and 320 nm with a xenon source, the sample may be ex
39、posed to considerably more than the 15 kWh.m2 of total irradiation specified for the wavelength range between 280 nm and 400 nm. A.3 UV-high pressure metal halide lamp These are high pressure mercury discharge lamps with metal halide additives which radiate mainly UVA and UVB. Special quartz glass s
40、hall be used to absorb the UVC radiation. This is also important in order to avoid the production of ozone. A.4 Natural sunlight Natural sunlight can be utilized with concentration. As with the xenon source, in order to achieve a total irradiation of 73 kWh.m-* between 280 nm and 320 nm, the sample
41、may be exposed to considerably more than the 15 kWhmr2 of total irradiation specified for the wavelength range between 280 nm and 400 nm.
