Solid biofuels — Determination of particle density of pellets and briquettes

This document specifies a method for determining the particle density of compressed fuels such as pellets or briquettes. Particle density is not an absolute value and conditions for its determination have to be standardized to enable comparative determinations to be made.

Biocombustibles solides — Détermination de la masse volumique unitaire des granulés et des briquettes

Le présent document spécifie une méthode de détermination de la masse volumique unitaire des combustibles comprimés tels que les granulés ou les briquettes. La masse volumique unitaire n'est pas une valeur absolue et les conditions nécessaires à sa détermination doivent être normalisées afin de pouvoir comparer les différentes déterminations.
