This International Standard describes artificial weathering tests for the evaluation of plastics in heavily polluted outdoor environments. The results of this International Standard cannot be used to predict the service life of these plastics. This International Standard describes two different exposure procedures. The application of these procedures depends on the type of plastic product being evaluated. In Method A, intended for products where surface degradation is critical, a strong acid spray (pH 1.5) is used for a short period of time. Method B uses a weaker acid spray (pH 3.5) applied over a longer period of time that can penetrate deeply into the product. It is intended for geotextiles and similar products. This International Standard does not cover the influence of specialty chemicals such as agrochemicals.
