BS EN 16718:2015 describes a method for determining total organic carbon by calculating the difference between the results of measurements of total carbon (TC) and total inorganic carbon (TIC). The identification of the bio-based content given by the stable isotopes such as13C is described also. This method is applicable to all wood species, wood-based materials (panels, plywood, wood-polymer, etc.) and woods containing chemicals in general.Cross References:EN 13183-1EN 13137EN 16449CEN/TR 16721EN ISO/IEC 17025NF P01-010BP X30-323All current amendments available at time of purchase are included with the purchase of this document.
