, 2 .6 3 , or

2 .6 4

. The VOC content of a tint base shall be determined without colorant that is

a dded after the tint base is manufactured. If the manufacturer does not recommend

thinning, the VOC Content must be calculated for the product as supplied. If the

manufacturer recommends thinning, the VOC Content must be calculated including the

maximum a mount of thinning solvent recommended by the manufacturer. If the

coating is a multi

- component product, the VOC content must be calculated as mixed or

catalyzed. If the coating contains silanes, siloxanes, or other ingredients that generate

ethanol or ot her VOCs during the curing process, the VOC content must include the

VOCs emitted during curing.

6.2 VOC Content of Coatings

To determine the physical properties of a coating in order to perform the calculations in

subsection 2 .6 2 or 2 .6 4 , the reference method for VOC content is U.S. EPA Method 24,

incorporated by reference in subsection 6 .5.9 , except as provided in subsections 6.3 and

BAAQMD Method 41 (Revised 1995), as applicable, incorporated by reference in

subsection s 6.5.8, 6.5.6, and 6.5.7, respectively . To determine the VOC content of a

coating, the manufacturer may use U.S. EPA Method 24, or an alt ernative method as

provided in subsection 6.3, formulation data, or any other reasonable means for

predicting that the coating has been formulated as intended (e.g., quality assurance

checks, record keeping). However, if there are any inconsistencies betw een 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 6.3. The District Air Pollution Control Officer (APCO) ma y require a

manufacturer to conduct a Method 24 analysis.

6.3 Alternative Test Methods
