ISO/DIS 15110
Abstract
This standard specifies the Acid Dew and Fog Test (ADF test) as a time compressed (time-lapse) laboratory test methods for simulating the damaging effects of acidic atmospheric precipitation in interaction with UV radiation, neutral condensed precipitation, and changing temperature and humidity with the use of artificial
acidic precipitation. These test methods are intended to evaluate the suitability of polymeric materials for use in outdoor environments with acidic precipitation on the basis of relative performance rankings. It is not intended to generate the same damage size and pattern as in outdoor weathering, but rather to result in a similar ranking. It produces a more homogenous damage of smaller scale, which allows smaller samples sizes (hence higher test sample throughput) and enables applying more objective means of evaluation than visual
assessment.
