Scope: This document specifies a method for the determination of moisture in a general analysis sample by drying the sample in an oven. This method is suitable for use for general analysis samples in accordance with CEN/TS 15414-1[3]1). It is applicable to all solid recovered fuels. If solid recovered fuels contain large amounts of oil-fractions the Karl-Fischer-Method (for example drying time until constant mass is achieved. NOTE The term moisture content, when used with recovered materials, can be misleading since solid recovered materials, e. g. biomass, frequently contain varying amounts of volatile compounds (extractives) which can evaporate when determining the moisture content of the general analyses sample by oven drying.
