NC-v4 EQc2: Low emitting materials
Inherently non-emitting sources cover materials such as "stone, ceramic,powder-coated metals, plated or anodized metal, glass, concrete, clay brick, unfinished or untreated solid wood flooring." Does hot-dipped galvanized fall into the same categroy? It seems like a pretty simple yes, but since it is not called out the team would like to double check. Thanks!

Applied in the shop or the field? Most of these products are high in solvents (about 50%). Once cured the solids content becomes very high (about 99%) and it should not continue to emit.

Thanks Susan. It is applied in the shop. Do you know if that would allow it to fall under the inherently non-emitting category, or would it still need to be tested?

It is non-emitting because it is metal coating when it arrived on site.

I had the same question and just did some research online. I learned through Wikipedia that galvanized metal uses a process of zinc-plating, which is in the general category of "plated metals" which is listed as acceptable as inherently non-emitting on the list.
