Effects of test conditions on formaldehyde emissions from whole wooden furniture were studied using a 30 m,3, large chamber. The results showed that the factor sequence of the test conditions on formaldehyde concentrations in air from the furniture samples was as follows: area bearing rate, temperature, air exchange rate and relative humidity. The area bearing rate, temperature and relative humidity were positively correlated to the formaldehyde emissions, while the area bearing rate was negatively correlated to the formaldehyde emissions.
