GVOC= WS - WW - WES
VM - Vw - Ves

Where:

GVOC = Grams VOC/L of Coating less water and Exempt Compounds
WS = weight of volatile compounds in grams
WW = weight of water in grams
WES = weight of Exempt Compounds in grams
VM = volume of material in liters
VW = volume of water in liters
VES = volume of Exempt Compounds in liters

For a basecoat/clearcoat system:

make gifs


VOCbc + 2VOCcc
VOCMS = 3

For a 3 Stage Coating system:
VOCbc + VOCmc + 2VOCcc
VOCMS = 4

For a 4 Stage Coating system:

VOCMS = VOCgc + VOCbc + VOCmc + 2VOCcc
5

Where:

VOCMS is the average of the VOC content, as applied, and used to determine compliance with the standards in subsection C.1.a.1.
