33、n of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.
34、 International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance wi
35、th the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires appro
36、val 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 patent rights.

38、produce the weathering effects that occur when plastics are exposed to heavily polluted outdoor environments. Acidic precipitation can have a significant effect on the photochemical ageing of many polymers. In some cases, this is due to attack on the stabilizers56or fillers like CaCO378applied in te
39、chnical polymers. The mechanisms differ from those of harmful gases, which essentially constitute the initial products of acidic precipitation. Arising from changing industrial air pollution and additionally diffused by the stochastic wind and cloud distribution, acidic precipitation occurs sporadic
40、ally. Thus, especially regarding acidic precipitation, outdoor weathering effects vary enormously within different years. Therefore, it is practically impossible to obtain reliable outdoor exposure results from just one season. These fluctuations can be avoided through the use of a laboratory test,
41、where all weathering parameters, including the acidic deposition, can be controlled. In artificial weathering tests for plastics, the action of acidic atmospheric precipitation, which is part of the real world, has generally not been considered.

43、luate plastics for use in heavily polluted outdoor environments. Results from this International Standard cannot be used to predict the service life of these plastics. This International Standard describes two different exposure methods. Use of the methods depends on the form of the plastic product
44、being evaluated. Method A is intended for products where surface degradation is very important and uses a strong acid spray (pH 1,5) that is applied for a short time. Method B uses a weaker acid spray (pH 3,5) that is applied over a long period of time so that it can penetrate deeply into the produc
45、t and is intended for products such as geotextiles and related products. This International Standard does not cover the influence of special chemicals like agrochemicals. 2 Normative references The following referenced documents are indispensable for the application of this document.

The acidic deposition, in some cases, may accele
49、rate the degradation of the polymer itself. In other cases, the degradation is accelerated when the acid deposition attacks the stabilizers in the polymer. Two different methods combine acidic deposition with artificial weathering. In method A, a strong acid solution is applied once per day. In method B, a weaker acid exposure is integrated in the rain phase. Both test methods aim for the same physical-chemical degradation mechanism as known to occur from exposure in heavily polluted outdoor environment. To consider different climatic conditions, m
