Protocol -- Emission tests are performed following California Dept. of Health Services “Standard Practice forthe Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers,”CA/DHS/EHLRB/R-174, 07/15/04 (http://www.cal-iaq.org/VOC/Section01350_7_15_2004_FINAL_PLUS_ADDENDUM-2004-01.pdf). This practice is based on ASTM D 5116, “Standard Guide for Small-Scale Environmental Chamber Determinations of Organic Emissions from Indoor Materials/Products” andincorporates the chamber testing portion of California Specification 01350(http://www.ciwmb.ca.gov/GreenBuilding/Specs/Section01350/). Project-specific results are calculated asdescribed in Specification 01350.Table 1.

Equations Used in CalculationsAn emission factor (EF) in µg m -2 h-1 for a chemical substance in a chamber test is calculated usingEquation 1:CommentsEF = (Q (C - Co)) / A C (1)where C is the chamber concentration of the substance (µg m -3 ) and Co is the corresponding substrate orchamber blank concentration (µg m -3 ). The other parameters are defined in Table 1. For an emitting unit,such as a chair, the number of units, N, is substituted for surface area, A C , and EF is expressed asµg/unit-h.A building concentration (C B ) in µg m -3 can be estimated from the EF using Equation 2:C B = (EF * A B ) / Q B (2)where A B is the area of the product in the building space and Q B is the outdoor air flow rate to the space.An EF in µmol m -2 h -1 for an individual VOC in a chamber test is calculated from the above EF usingEquation 3:EF (µmol m -2 h -1 ) = EF (µg m -2 h -1 ) / MW (3)where MW is the molecular weight (molar mass) of the respective compound.A chamber concentration in ppb (molar basis) for an individual VOC is calculated from the chamberconcentration (C – Co) in µg m -3 using Equation 4:Chamber concentration (ppb) = (C – Co) x 24.45 / MW (4)where 24.45, in L/mol, is the molar volume of air at standard conditions (1 atm pressure, 25 o C).For a furniture component, the workstation concentration of formaldehyde and total aldehydes in ppb canbe estimated from the corresponding aldehyde EF (µmol m -2 h-1) using Equation 5:WS Aldehyde concentration (ppb) = (EF aldehyde )(A ws )(24.45) / Q ws (5)where A ws is the surface area of the component in the workstation (m 2 ) and Q ws is the outdoor air flowrate to the workstation (m 3 /h).The emission factor calculations are based on the area of both surfaces. According to the attachedCOC, the tested sample is representative of all Emilceramica and Ergon brands of ceramic porcelaintile (Group Bla).END OF REPORT333-001-01A-Mar0408 Berkeley Analytical Associates, LLC.
