Paints and varnishes -- Determination of resistance to humid atmospheres containing sulfur dioxide

The principle of the procedure specified is to expose a coated test panel to specified humid atmospheres containing sulfur dioxide. A volume of 0,2 litre, measured at atmospheric pressure, is generally recommended for testing coatings of thickness not exceeding approximately 40 µm. The effects of exposure are evaluated by criteria agreed in advance between the interested parties, these criteria being usually of a subjective nature. Applies to single-coat film or a multi-coat system of paints.
