Most Restrictive VOC limit in Subsection B.2 and the corresponding Labeling 

Requirement in Section C, if applicable, shall be considered in compliance with this 

rule. 

G. Testing Procedures: 

 1. Volatile Organic Compound Content: To determine the physical properties of a 

coating in order to perform the calculations in Section J.61 or J.63, the reference 

method for VOC content is EPA Method 24, incorporated by reference in Subsection 

G.4.i, except as provided in Subsections G.2 and G.3. An alternative method to 

determine the VOC content of coatings is the SCAQMD Method 304-91 (Revised 

February 1996), incorporated by reference in Subsection G.4.j. The exempt 

compounds content shall be determined by test methods referenced in Subsections 

G.4.f, G.4.g, or G.4.h, as applicable. To determine the VOC content of a coating, the 

manufacturer may use USEPA Method 24, or an alternative method as provided in 

Subsection G.2, formulation data, or any reasonable means for predicting that the 

coating has been formulated as intended (e.g. quality assurance checks, 

recordkeeping). However, if there are any inconsistencies between the results of a 

Method 24 test and any other means for determining VOC content, the Method 24 

test results will govern, except when an alternative method is approved as specified 

in Subsection G.2. The APCO may require the manufacturer to conduct a Method 24 

analysis. 

 2. Alternative Test Method: Other test methods demonstrated to provide results that 

are acceptable for purposes of determining compliance with Subsection G.1, after 

review and approval in writing by the staffs of the District, ARB and United States 

Environmental Protection Agency, may also be used. 

3. Methacrylate Traffic Marking Coatings: Analysis of methacrylate multicomponent 

coatings used as traffic marking coatings shall be conducted according to a 

modification of U.S. Environmental Protection Agency Method 24 (40 CFR 59, 

subpart D, Appendix A), incorporated by reference in Section G.4.k. This method 

has not been approved for methacrylate multicomponent coatings used for purposes 

other than as traffic marking coatings or for other classes of multicomponent 

coatings.
