Has anyone had any success on this credit? We cannot seem to locate any manufacturers that provide testing information on the lead in their wires. We have found a manufacturer that has a LEED letter for their product stating that lead is under the 300 ppm threshold, but also lead free, which is conflicting. When asked, GBCI stated this letter would likely not be approved. 

Who has achieved these two points, and what manufacturer did you use?

Inquiry: We sent in a LEED letter from a manufacturer, but it seemed to have conflicting information.

"The manufacturer documentation must explicitly address the presence or absence of lead either by stating either a) the amount of lead (and/or cadmium, etc.) or, b) stating the regulation the product complies with. Acceptable regulations for lead include California AB1953; NSF International certifies products to this standard under NSF 61 and NSF 372. Language such as “per AB1953” and/or “100% lead-free” is acceptable. GBCI will also accept testing data provided by the manufacturer for their product. Teams can demonstrate compliance by simply being in conformance to California AB1953 (for both the solder and the flux requirements).

There are two statements about lead content that might be interpreted as contradictory. One says the products "do not contain any lead, mercury, or asbestos," and the other says the products "do not exceed lead, mercury, or asbestos content of 300 ppm," which could imply there is some content between zero and 300 ppm."
