This document describes the method of determining the moisture in the analysis sample by drying the sample in an oven. It is intended to be used for general analysis samples according to ISO WD XXXXX (14780). The method described in this document is applicable to all solid biofuels.
Since biofuels in small particle size are very hygroscopic, their moisture content will vary with the change of humidity of the atmosphere and therefore, the moisture of the analyses sample should always be determined simultaneously when portions are weighed out for other analytical determinations, for example calorific value, carbon, nitrogen.
