Date Feb. 6, 1997A method for determination of parameters of wood panels, which comprises analyzing the raw wood material/panels at a moisture content 10% by a spectrometric method giving spectral data, and comparing spectral data with reference data from reference material/panels calibrated to known parameters of panels produced from the reference material or of the reference panel by multivariate analysis. Control of process variables influencing parameters of the panels, which comprises analyzing the material/panels, linking spectral data into a combination with desired parameters, and comparing the combination with reference combinations consisting of reference data from reference material/panels linked with known parameters of the reference material/panels, the reference combinations being calibrated to known variables by multivariate analysis.
