A new testing method for determining the density of wood pellets and briquettes has been accredited according to the standard EN ISO 18847:2016 methodology. This parameter is used in assessing the quality of wood pellets and briquettes and is included in the specifications of these products. It provides information on the degree of compaction of wood, the energy content of the product, as well as the result of the technological process of production. We offer our customers to include in their testing programs, along with other quality indicators, also the determination of this parameter to confirm the quality compliance of their products and obtain objective information for the management of the production process.
