Calculation 1:
The VOC content of a basecoat/topcoat system shall be calculated according to the following equation:
where
VOCms = the composite VOC content, less water and less exempt compounds, to be used for compliance determination under the multistage topcoat system coating category.
VOCbc = the VOC content, less water and less exempt compounds as applied, of any given basecoat.
VOCcc = the VOC content, less water and less exempt compounds as applied, of any given clearcoat.
Calculation 2:
The VOC content per gallon of any coating, less water and less exempt compounds, shall be calculated by the following equation:
where
Pounds of VOC per gallon of coating, less water and less exempt compounds is the weight of VOC per combined volume of VOC and coating solids.
Ws = weight of volatile compounds in pounds.
Ww = weight of water in pounds.
Wes = weight of exempt compounds in pounds.
Vm = volume of material in gallons.
Vw = volume of water in gallons.
Ves = volume of exempt compounds in gallons.
Calculation 3:
The VOC content of any coating shall be calculated by the following equation:
where
Ws = weight of volatile compounds in pounds.
Ww = weight of water in pounds.
Wes = weight of exempt compounds in pounds.
Vm = volume of material in gallons.
Calculation 4:
The VOC content of a three-stage topcoat system shall be calculated according to the equation:
where
A three-stage topcoat system is a topcoat system composed of a basecoat portion, a midcoat portion, and a transparent clearcoat portion.
VOCms = the composite VOC content, less water and less exempt compounds, to be used for compliance determination under the multistage topcoat system coating category.
VOCbc = the VOC content, less water and less exempt compounds as applied, of any give basecoat.
VOCmc = the VOC content, less water and less exempt compounds as applied, of any give midcoat.
VOCcc = the VOC content, less water and less exempt compounds as applied, of any given clearcoat.
