Calculation. The weighted average lead content of a pipe, pipe
fitting, plumbing fitting, or fixture shall be calculated by using

surface area of that component to the total wetted surface area of
the entire product to arrive at the weighted percentage of lead of
the component. The weighted percentage of lead of each wetted component
shall be added together, and the sum of these weighted percentages
shall constitute the weighted average lead content of the product.
The lead content of the material used to produce wetted components
shall be used to determine compliance with paragraph (1)(b), above.
For lead content of materials that are provided as a range, the maximum
content of the range shall be used.
