Abstract The wood-based panel formaldehyde emission was tested by the desiccators method in GB/T 17657-2013 "Test method for physicochemical properties of wood-based panel ", the process of the detection was studied. All kinds of uncertainties were analyzed, which affected determination of formaldehyde emission and evaluated the components of uncertainty according to the JJF 1059.1-2012 "Evaluation and Expression of Uncertainty in Measurement" . The results showed that the formaldehyde emission was (1.06±0.05) mg·L-1, when expanded uncertainty coverage factor k=2, fiducially probability P=95％. The analysis showed that the uncertainty of the reference value and the repeated determination of the sample contributed the most, followed by the uncertainty which was introduced by the variation of the standard curve fitting.
