Title = Observations on Application of the Field and Laboratory Emission Cell (FLEC) for Latex Paint Emission -- Effect of Relative Humidity 
Abstract = The U.S Environmental Protection Agency (EPA) Air Pollution Prevention and Control Division (APPCD) has performed testing for products with different surface and mass transfer characteristics to evaluate the application of the Field and Laboratory Emission Cell (FLEC) for field studies. The goal of these tests has been to gain a better understanding of the effects of the FLEC operating parameters (e.g., high air exchange, high loading, low velocity). During recent tests, the impact of relative humidity (RH) on emissions from latex paint applied to gypsum board was investigated because RH may impact how the FLEC could be used in field studies. Dynamic emissions tests in small (53 l) chambers showed that RH levels in the chamber affected emissions of ethylene glycol, but had little impact on Texanol. The data suggested that the FLEC must be used with a humidified air source, which was demonstrated in a subsequent experiment. When operated with supply air at 50% RH, emissions measurements for ethylene glycol with the FLEC were comparable to results with small chambers, but Texanol measurements suggested that further evaluations are required.
