This part of ISO 18134 describes the method of determining the moisture in the analysis test sample bydrying in an oven. It is intended to be used for general analysis samples in accordance with EN 14780.The method described in this part of ISO 18134 is applicable to all solid biofuels. The moisture contentof solid biofuels (as received) is always reported based on the total mass of the test sample (wet basis).Since biofuels in small particle size are very hygroscopic, their moisture content will change withhumidity in the atmosphere and therefore, the moisture of the test portion is determined simultaneouslywith determination of for example calorific value, carbon content, and nitrogen content.NOTE The term moisture content when used with biomass materials can be misleading since untreatedbiomass frequently contains varying amounts of volatile compounds (extractives) which can evaporate whendetermining the moisture content by oven drying (see References [1] and [2]).
