We have a project that requires sheet vinyl flooring that is "static dissipative and static conductive". The conductive adhesive has 56 g/L VOC. The adhesive is for use only with homogenous vinyl tile and sheet vinyl (not VCT).
I'm proposing that the adhesive meets SCAQMD #1168 (c) Requirements (1): "Unless otherwise specified in paragraph (c)(2), a person shall not apply any adhesives, adhesive bonding primers, adhesive primers, or any other primer, which have a VOC content in excess of 250 g/L less water and less exempt compounds."
(c)(2) refers to the VOC table that we all know and love, and covers VCT Tile adhesives, but not vinyl adhesives.
Has anyone any experience with this?
Thanks.

That's not a straight forward call. If it was a product that was intended for both VCT and sheet vinyl (as some products are) it would be easier to say it should follow the VCT Tile limit of 50. My reading of Rule 1168 doesn't find clear guidance on sheet vinyl flooring - the Rubber Flooring Adhesive definition does indicate it applies to both tile and sheet products, whereas the VCT definition doesn't say anything about sheet vinyl.
Since you'll need to make a judgement on how this material should be classified, that decision may be influenced by how far off this is from the lower VOC limit (not much), how it would affect doing a VOC budget given your other materials, are you being consistent with the overall credit intent etc. Hope that helps - sorry this is one of those grey areas.

back to 2011. Do we have an answer of the classification of Static Dissipative Tiles?
I have a submittal for an adhesive for SDT at 56 g/L VOC.
The manufacturer is telling me that Rule 1168 does not classify SDT as VCT - that they are Solid Vinyl Tile (not Vinyl Composition) and therefore do not need to meet the 50 g/L VOC limit. According to him, they are classified as 'undefined' and therefore the limit is 250 g/L VOC with the Oct 6 2017 Amended Rule 1168.
Anybody have a thought on this before I reject a submittal for 6 g/L VOC?

I think your manufacturer is wrong.
The 2017 amendment to 1168 defines VCT as follows: "VINYL COMPOSITIONS [sic] TILE (VCT) is a material made from thermoplastic resins, fillers, and pigments." Note this is not the vinyl flooring industry definition of VCT, so SDT is a VCT in this context, as is luxury vinyl tile (LVT), which isn't technically a VCT either. But even if it SDT did not fit the VCT definition, it would still fall under 1168 "All Other Indoor Floor Covering Adhesives," and that standard is 50g/l as well. Note there are many <50 g/l 1168-compliant, Floorscore-certified adhesives for static-dissipative vinyl, so I would look to those products.
Good Luck!
