BS EN 16785-2:2018规定了使用适用于生产单元中代表性产品批次的物料平衡来确定产品中生物基含量的方法。本欧洲标准适用于通过化学合成、混合或组装获得的任何含碳固体、液体和气体生物基产品，前提是:对于一个产品批次，产品的成分以及生产单元中每个输入、输出和损失的生物基含量已知；产品的生物成分可以通过分析来验证。该方法仅包含最终产品中存在的输入和输出流的物理部分，不包含生产过程中使用的能量的材料输入。这种方法不需要测定生物活性- 完全来源于生物质的天然产品中的基础含量。交叉引用:EN 16575EN 16785-1购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN 16785-2:2018 specifies a method of determining the bio-based content in products using the material balance applied to a representative product batch in a production unit.This European Standard is applicable to any solid, liquid and gaseous bio-based product containing carbon, obtained by chemical synthesis, mixing or assembling, provided that:for a product batch, the composition of the product and the bio-based content of each input, output and loss in the production unit are known; andthe bio-based content of the product is verifiable by analysis.This method incorporates only the physical parts of the input and output stream as present in the final product, and does not incorporate material inputs for the energy to be used during the production process.This method is not needed for the determination of the bio-based content in natural products wholly derived from biomass.Cross References:EN 16575EN 16785-1All current amendments available at time of purchase are included with the purchase of this document.
