ISO 18134-1:2015描述了通过在烘箱中干燥来确定固体生物燃料的测试样品的总水分含量的方法，并且可以在需要高精度测定含水量时使用。本国际标准中描述的方法适用于所有固体生物燃料。固体生物燃料（如接收）的含水量总是基于测试样品的总质量（湿基）报告。 注意术语水分含量与生物质材料一起使用可能会产生误导，因为未经处理的生物质通常通过烘箱干燥确定含水量时可能会挥发的挥发性化合物（提取物）含量不同（参见参考文献[2]和[3]）

ISO 18134-1:2015 describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and may be used when high precision of the determination of moisture content is necessary. The method described in this International Standard is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total mass of the test sample (wet basis). NOTE The term moisture content, when used with biomass materials, can be misleading since untreated biomass frequently contains varying amounts of volatile compounds (extractives) which might evaporate when determining moisture content by oven drying (see References [2] and [3]).
