NR 440.74(6)(a)(a) Method 24 is used to determine the VOC content in coatings. If it is demonstrated to the satisfaction of the administrator that 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 collected in a 1-liter container at a point in the process where the sample will be representative of the coating applied to the substrate, 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 collected. 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.

NR 440.74(6)(b)(b) Method 25 shall be used to determine VOC concentrations from incinerator gas streams. Alternative Methods (18 or 25A), may be used as explained in the applicability section of Method 25 in cases where use of Method 25 is demonstrated to be technically infeasible.
