HPVA supports the California Air Resources Board (CARB) emission limits for hardwood plywood (HWPW) becoming national standards. The CARB emission limits for hardwood plywood have recently been incorporated into two national consensus standards with third party certification requirements similar to the CARB requirements. The ANSI/HPVA HP-1-2009 and ANSI/HPVA EF 2009 consensus standards also include other physical performance properties for these products. HWPW is the unfinished material used to manufacture engineered wood flooring (EWF). While the emission requirements are the same, the ANSI/HPVA EF 2009 national consensus standard requires that the finished consumer product meet those requirements while CARB requires the certification testing be on the unfinished HWPW material before finishing. The ANSI/HPVA EF 2009 standard tests the finished product as a consumer would use it.
HWPW has the lowest emission standard of any of the regulated composite wood panel products under the CARB regulations. The Phase 2 emission limit for veneer core HWPW, which comprise about 80% of the HWPW produced in North America, has been in place since January 1, 2010. This limit is 0.05ppm. The CARB emission limits are now de facto national standards being met by this industry.
Of the 90% of the HWPW and EF products that HPVA certifies as an officially recognized Third Party Certification organization (TPC-8), we estimate that over 60% of that production meets emission standards low enough to qualify for exemption. To achieve that level of production performance, no test can exceed 0.05ppm and 90% must be tested at 0.04ppm or below. Typically, exemption qualifying production operates with additional margins below even those low limits.
