“…This paper reported chambertesting studies of formaldehyde emissions from composite and solid wood furniture for up to 4000 h. Since no information was available on how the products being handled before purchasing, the measured formaldehyde emissions from the furniture were solely being used to evaluate formaldehyde source emission models in this study. Our results, consistent with results of previous research (Zhu et al, 2001;Guo, 2002), demonstrate a better fit with the power-law decay model than with the commonly used firstorder decay model (Guo, 2002). The first-order decay model, severely underestimates formaldehyde emissions from composite wood furniture over a longer period of time (e.g.…”

“…Model prediction could be used to predict long term emission performance of building materials according to short term test. For example, power-law model [18] proposed by BIFMA [19] could be used to estimate emission rate of furniture at day 14 based on test results at day 3 and day 7. However, this model is empirical model, and it is only used to predict emission rate at day 14 or less [19].…”

Labeling of volatile organic compounds emissions from Chinese furniture: Consideration and practice

Volatile organic compounds (VOCs) emitted from furniture are recognized as a main cause of bad indoor air quality. In European countries and the U.S., labeling systems for furniture have been established with good effect to address this issue. However, there are problems with these labeling systems. For example, too many VOCs were targeted, and the testing time was too long (7-28 d). Aiming at solving these problems, solutions are put forward to establish furniture VOCs emissions labeling system in China and some practices are introduced in this paper. They are: some furniture popular in the market were tested and main VOCs emitted from these furniture were identified; furniture loading factors in residential homes were surveyed, and reference bedroom and reference living room were established according to the survey results to make emission rate thresholds of furniture; C-history method was developed and applied to testing furniture which could shorten the testing time to 3 d; a reference toluene sample for assessing the precision of the test results of chamber system was prepared. These works are technically helpful for establishing furniture VOCs labeling system in China.indoor air quality (IAQ), formaldehyde, chamber, building environment Citation:

An approximate integral method for volatile compounds emission from plate is presented in this paper. The gas-phase mass transfer resistance was neglected for simplifying computation. Compared to Laplace Transformation Method, the method suggested is simple, and emission flux, chamber concentration of volatile compounds and concentration distribution of volatile compounds in the material can be determined conveniently. Results of the present method show good agreement with experimental data. The influence of C0, D, K and N on concentration of total volatile organic compounds (TVOC) in the air is also calculated .
