(a) Method 24 is used to determine the VOC content in coatings. If it is demonstrated to the satisfaction of the administrator that plant coating formulation data are equivalent to Method 24 results, formulation data may be used. In the event of any inconsistency between a Method 24 test and a facility's formulation data, the Method 24 test will govern. For Method 24, the coating sample shall be a 1-liter sample taken into a 1-liter container at a location and time such that the sample will be representative of the coating applied to the base film, that is, the sample shall include any dilution solvent or other VOC added during the manufacturing process. The container shall be tightly sealed immediately after the sample is taken. Any solvent or other VOC added after the sample is taken shall be measured and accounted for in the calculations that use Method 24 results.

par. (b) 1. and
2., the test shall consist of 3 separate runs, each lasting a minimum of 30 minutes.
