Effect of loading ratio, conditioning time and air exchange rate on the formaldehyde emission from wood-based board using large chamber and desiccator method

In case of reduction of the loading ratios, the good correlation between the large chamber method and the desiccator test could be obtained for particleboard tested. With the reduction of the loading ratios, the correlation between the large chamber method and the desiccator test was improved. At the loading ratio of 0.04 ft2/ft3, the coefficients of determination (R2) showed 0.995 for 0.5 AC/HR, and 0.989 for 1.0 AC/HR. Large chamber emission rate at 1.0 AC/HR was 0.727 time Large chamber emission rate at 0.5 AC/HR.
