Title = Characterization of Emissions from Building Products: Long-term Chemical Evaluation. The Impact of Air Velocity, Temperature, Humidity, Oxygen, and Batch/Repeatability in the FLEC. 
Abstract = The emissions of two critical VOCs from five building products (BPs) were measured in the FLEC up to 250 days. The BPs (VOCs selected on the basis of low human odor thresholds and abundance) were: nylon carpet with latex backing (2-ethylhexanol, 4-phenylcyclohexene), PVC flooring (2-ethylhexanol, phenol), floor varnish on pretreated beechwood parquet (butyl acetate, N-methylpyrrolidone), sealant (hexane, 3,7-dimethyloctanol), and waterborne wall paint on gypsum board (1,2-propandiol, Texanol). Ten different experimental conditions were tested: four different air velocities (1, 2, 5, ca. 9 cm/s), three different temperatures (23, 35 and 60 C), two different rel. humidifies (0 and 50% RH), and nitrogen instead of air. Additionally, two sample specimen and two different batches were compared for repeatability and homogeneity. Primary emissions were not affected by the air velocity after a few days to any great extent. Secondary (oxidative) emissions were observed depending on the type of BP and VOC. Both the temperature and rel. humidity affected the emissions depending on the type of BP and type of VOC. Anaerobic emission test conditions may provide more "true" emission rates for susceptible BPs. The time value concept, as used in the Danish labeling scheme, appears to be a good approach for interlaboratory comparison experiments.
