25、ciples and procedure for determining the resistance of an organic coating on a metallic substrate (coil coating) to a combination of fluorescent UV radiation, and water condensation and temperature under controlled conditions. Due to varied conditions which occur during natural weathering and the ex

26、treme nature of accelerated testing, correlation between the two cannot be expected. Not all organic coatings will perform on an equal basis but a degree of correlation between the same generic type might be observed. 2 Normative references The following referenced documents are indispensable for th

30、oating is exposed in a cyclic manner to UV radiation, condensation of water and temperature under controlled conditions. One of two types of fluorescent UV lamps, UVA-340 or UVB-313, are used. After exposure to UV radiation under controlled conditions chalking and changes in gloss and colour are ass

31、essed. 5 Apparatus and materials Ordinary laboratory apparatus and glassware, together with the following. 5.1 Test chamber.

32、 13523-10:2010EN 13523-10:2010 (E) 6 The test chamber shall be constructed of corrosion resistant materials. Enclosed within the test chamber shall be eight fluorescent lamps (5.2), a heater pan, racks for test specimens, and provisions for indicating and controlling operating times and temperatures

33、. The lamps shall be in banks of four on either side of the cabinet. Electrical operating conditions for the lamps shall be as given by the manufacturer. 5.2 UV lamps. Either UVA-340 or UVB-313, as specified in EN ISO 11507: UVA-340 starting at a wavelength of approximately 300 nm with a peak emissi

34、on at 340 nm; UVB-313 starting at a wavelength of approximately 280 nm with a peak emission at 313 nm. 5.3 Water supply. Deionized water. 6 Sampling See EN 13523-0. 7 Test panels See EN 13523-0. The test specimens shall be flat and about 150 mm 75 mm in size. NOTE Deviations from the standard method

35、s of panel shape, size, previous working, or conditioning may be agreed between the interested parties. 8 Procedure 8.1 Exposure Place the test specimens in racks which are made of inert material. Expose the face of the test specimens parallel to the lamps at a distance of about 50 mm from the neare

36、st surface of the lamp. If there are empty spaces within the racks fill these with blanks to maintain the conditions within the test chamber. Cycle the test specimens through periods of 4 h of dry UV exposure at a black panel temperature of (60 3) C, followed by a period of 4 h of water condensation

37、 exposure, without radiation, at a black panel temperature of (40 3) C. (One cycle consists of 8 h exposure.) Arrange the test specimens to allow the condensate to freely run off the surface under gravity. Conclude the exposure at an agreed time, for example 2 000 h for UVA-340 or 1 000 h for UVB-31

38、3, or an agreed number of cycles, for example 250 cycles for UVA-340 or 125 cycles for UVB-313. NOTE Where possible, use an agreed irradiance level, typically 0,89 W/m for UVA-340 or 0,71 W/m for UVB-313.

For apparatus w

40、ithout the possibility to set the irradiance, after every usage of 400 radiation hours, replace one lamp and rotate the others within the bank with the oldest lamp being taken out of service unless otherwise specified by the equipment manufacturer. For apparatus with irradiance measurement the appar

41、atus indicates when the radiation sensors need to be calibrated. Carry out the calibration of the radiation sensors according to the method provided by the equipment manufacturer using the calibration equipment. When the irradiance of a lamp falls below the set point, it shall be replaced. This is u

42、sually triggered by an alarm on the equipment. 8.3 Evaluation of test specimens At the conclusion of the exposure evaluate the test specimens for chalking, changes of gloss and colour. Assess the coating for chalking, change of gloss and change of colour at ambient temperature. For more accurate mea

43、surements, as required for instance in case of dispute, the temperature shall be (23 2) C and the relative humidity (50 5) %, in accordance with EN 23270. 9 Expression of results The results shall be expressed as comparison between an unexposed test specimen and an exposed test specimen for properti

44、es defined in EN 13523-2, EN 13523-3, EN 13523-14 and EN 13523-22, if appropriate in terms of, for example, x % gloss retention EN 13523-2, E*b = y EN 13523-3, z chalking EN 13523-14. 10 Precision No precision data are currently available. 11 Test report The test report shall contain at least the fo

45、llowing information: a) all details necessary to identify the product tested; b) reference to this part of EN 13523 (EN 13523-10); c) type of UV lamps used; d) duration of exposure in hours (h); e) results of the test, as indicated in Clause 9; f) any deviation, by agreement or otherwise, from the t

46、est method specified; g) date(s) of the test.
