ISO 17828:2015定义了使用标准测量容器测定固体生物燃料体积密度的方法。该方法适用于标称顶部尺寸最大为100 mm的所有可浇注固体生物燃料。 堆积密度不是绝对值；因此，必须对其测定条件进行标准化，以获得比较测量结果。 注:由于振动、冲击、压力、生物降解、干燥和湿润等因素，固体生物燃料的体积密度会发生变化。 因此，在运输、储存或转运过程中，测量的体积密度可能会偏离实际情况。

ISO 17828:2015 defines a method of determining bulk density of solid biofuels by the use of a standard measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 100 mm. Bulk density is not an absolute value; therefore, conditions for its determination have to be standardized in order to gain comparative measuring results. NOTE Bulk density of solid biofuels is subject to variation due to several factors such as vibration, shock, pressure, biodegradation, drying, and wetting. Measured bulk density can therefore deviate from actual conditions during transportation, storage, or transhipment.
