Influencing factors, repeatability and correlation of chamber methods in measuring formaldehyde emissions from fiber- and particleboards

Abstract Recently, there has been focus on lowering emission levels of wood-based boards. However, the accuracy and correlation between EN 717-1 and ASTM D 6007 chamber methods at emission levels below 0.05 ppm are not well investigated, and information about their correlation to the EN 16516 method is limited. In this paper, the low emission level of interest was determined by measuring emissions from particles, fibers and pressed boards without glue. The effect of analytical methods and edge-sealing on chamber emissions was determined, and accuracies and correlations of the EN 717-1 and ASTM D 6007 chambers were defined at low emission levels (
