If the actual area -specific entiusum rates of a building material or famishing is needed (i e. <br />the initial emission rates estimates from the product certifications are higherdtan desired), <br />then that data can be acquired by requesting from the manufacturer the complete chemical <br />emission rate test report. For instance if the complete CDPH emission test report is <br />requested for a CDHP cettified product, that report will provide the actual area -specific <br />emission rates for not only the 35 specific VOCs, including formaldehyde, listed in Table <br />4-1 of the CDPH test method (CDPH, 2017), but also all of the cancer and <br />reproductive/developmental chemicals listed in the California Proposition 65 Safe Harbor <br />Levels (OEHIIA, 2017a)_ all of the toxic air contaminants (TACs) in the California Air <br />Resources Board'roxic Air Contamination List (CARE, 2011), and the 10 chemicals with <br />the greatest emission rates. <br />Alternatively, a sample of the building material or furnishing can be submitted to a <br />chemical emission rate testing laboratory, such as Berkeley Analytical Laboratory <br />(hops-l/berkcicyanalytical_cour), to measure the formaldehyde emission rate. <br />4.) Calcuate the "Dotal Formaldehyde Emission Rate. For each IAQ Zone, calculate the <br />total formaldehyde emission rate (i.e. µglh) from the individual formaldehyde emission <br />rates from each of the building material/fitmishings as determined in Step 3. <br />5.) Calculate the Indoor Formaldehyde Concentration. For each IAQ Zone, calculate the <br />indoor formaldehyde concentration (µg/m3) from Equation II by dividing the total <br />formaldehyde emission rates (i.e. µg/h) as determined in Step 4, by the design minimum <br />outdoor air ventilation rate (ms/h) for the IAQ <br />Etq <br />where: <br />Cm = indoor formaldehyde concentration (µglm3) <br />Etaai = total fonualdchvdc emission rate (µgill) into the IAQ Zone_ <br />Q,, — design minimum outdoor air ventilation rate to the IAQ Zone (m3lh) <br />The above Equation 1 is basedupon mass balance theory, and is referenced in Section <br />SOf19 <br />22 <br />75C-45 <br />
