The work of preparing International Standards is normally carried out through ISO technical committees. Each
19、member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
20、 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards ad
21、opted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of pat

23、3(E)IntroductionThis International Standard specifies a method of simulating the damaging effect of outdoor weathering with relevance to acidic atmospheric precipitation on polymeric products. In addition to the classical environmental variables of temperature and humidity, acidic atmospheric precip
24、itation can also have a significant effect on the photochemical ageing of polymers, e.g. by attacking the stabilizers. The mechanisms differ from those of harmful gases, which essentially constitute the initial products of acidic precipitation.Arising from changing industrial air pollution and addit
25、ionally diffused by the stochastic wind and cloud distribution, acidic precipitation occurs sporadically. Thus, especially regarding acidic precipitation, outdoor weathering effects vary enormously within different years. Therefore, it is practically impossible to obtain reliable outdoor exposure re
26、sults from just one season. These fluctuations can be avoided through the use of a laboratory test, where all weathering parameters, including the acidic deposition, can be controlled.The method is based on VDI Guideline VDI 3958-12.9 ISO 2013 All rights reserved vBS EN ISO 15110:2013BS EN ISO 15110
27、:2013Paints and varnishes Artificial weathering including acidic deposition1 ScopeThis International Standard specifies a so-called acid dew and fog test (ADF test) as an accelerated laboratory test method for simulating, by the use of artificial acidic precipitation, the damaging effects of acidic
28、atmospheric precipitation in association with UV radiation, neutral condensed precipitation, and changing temperature and humidity. This test method is intended to be used in evaluating, on the basis of relative performance rankings, the suitability of polymeric materials for use in outdoor environm
29、ents with acidic precipitation. It is not intended to generate the same extent of damage or the same damage pattern as in outdoor weathering, but rather to give a ranking which is similar to that which would be obtained in outdoor weathering. The method produces damage which is more homogeneous, all
30、ows fewer specimens to be exposed (and hence more rapid testing) and enables evaluation of the exposed specimens to be carried out using methods which are more objective than visual assessment.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this docu
31、ment and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.ISO 4892-1, Plastics Methods of exposure to laboratory light sources Part 1: General guidance
32、ISO 4892-2:2006, Plastics Methods of exposure to laboratory light sources Part 2: Xenon-arc lampsISO 4892-3:2006, Plastics Methods of exposure to laboratory light sources Part 3: Fluorescent UV lamps3 PrincipleThe combined action of solar UV radiation, heat, humidity, wetting and acidic deposition i
33、s simulated in weathering devices similar to those described in ISO 4892-2 and ISO 16474-2 for xenon-arc lamps, and in ISO 4892-3 and ISO 16474-3 for fluorescent UV lamps.Included in the artificial exposure is an acidic exposure, which is accomplished by a once-per-day spraying of acid. The aim of t
34、his test is not to reproduce the visual damage patterns which result from outdoor exposures, which show a very widespread distribution that is hard to evaluate. Rather, the aim is to reproduce the same ranking which would be obtained with an outdoor exposure, by causing damage by the same mechanisms
35、 but creating a homogeneous distribution on a smaller scale that can be evaluated in an objective way.Accelerated weathering is achieved by the serial arrangement of the worst conceivable combinations of environmental conditions for the object under test (referred to hereafter as the “worst-case sce
36、nario”). This is accomplished by reproducing these environmental conditions in a more compressed sequence than would be the case outdoors and by including artificial acidic precipitation. However, the values of the environmental conditions used do not significantly exceed those encountered in practi
37、ce outdoors.INTERNATIONAL STANDARD ISO 15110:2013(E) ISO 2013 All rights reserved 1BS EN ISO 15110:2013ISO 15110:2013(E)4 Apparatus4.1 GeneralFor this test, weathering devices as specified in either ISO 4892-2 or ISO 4892-3 shall be used.

47、id mixture with a pH of 1,5 at (25 2) C by dissolving 10,6 g of H2SO4, 3,18 g of HNO3and 1,80 g of HCl in 10 l of demineralized water (this gives a mass ratio of 1,0:0,3:0,17). These quantities refer to acids with a calculated concentration of 100 %. Depending on the mass concentrations of the acids
48、 available, larger quantities of acid might have to be weighed out (e.g. if 36 % HCl is used, the quantity will have to be 1,8/0,36 = 5,0 g). Analytical-grade acids shall be used.Then prepare a solution with a pH of 2,5 by diluting the pH 1,5 solution with demineralized water by a volume ratio of 1:
49、10.The pH 2,5 solution is the recommended solution. However, the more agressive pH 1,5 solution may be used if agreed upon by the interested parties. If the pH 1,5 solution is used, this shall be mentioned in the test report.Before starting the exposure, check the pH-value of the solution using, for instance, pH test strips. If it deviates by more than pH 0,3 from the theoretical value, replace the solution.To avoid changes in the pH-value of the solution, store it in an airtight container.Acid spraying may be carried out either manually
