1 Scope
This International Standard is one of a series of standards dealing with the testing
of paints, varnishes and related products. This International Standard specifies a
procedure for determining the resistance of a single-coat film or a multi-coat system
of paints or related products to humid atmospheres containing sulfur dioxide.
The test method allows for different amounts of 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.
