Hi, this is Josef Abboud with Atelier Ten.
An aspect of the VOC general emissions evaluation is unclear: the definition within the LEED reference guide for the general emissions test claims the manufacturer must state the range of VOCs after 14 days (336 hours), measured as specified in the CDPH Standard Method v1.1.
However, Section 126.96.36.199.2 of the CDPH v1.1-2010 indicates that an average time of 96 +/- 2 hours is sufficient for the full characterization of VOC emissions.
A manufacturer we're working with has a catalog of sealants tested up to 96 hours, which according to the definition in the LEED reference guide is non-compliant, but according to the CDPH is fine.
If anyone could please clarify how this should be handled, it would be very much appreciated.
