The original material is the material before any VOC-containing material such as solvent is added for purposes of mixing or thinning. The VOC content shall exclude any colorant added to a tint base. The weight of VOC per total volume of material shall be calculated by the following equation:

Where:
G2 = Weight of VOC per total volume of material.
