本技术报告概述了可用于确定固体，液体和气体产品的生物基含量的方法。它更具体地描述: a）使用放射性碳分析和元素分析的方法:该方法基于产品组成的陈述和验证; b）基于稳定同位素比例测量的方法;和 c）基于物料平衡的方法。 本技术报告对不同方法的适用性提供指导。 本技术报告还提出了进一步制定欧洲标准以确定生物基内容的建议

This Technical Report gives an overview of methods which can be used for the determination of the bio-based content of solid, liquid and gaseous products. It describes more specifically: a) a method using the radiocarbon analysis and elemental analysis: this method is based on a statement and a verification of the composition of the products; b) methods based on measurement of stable isotopic ratio; and c) a method based on the material balance. This Technical Report gives guidance on the applicability of the different methods. This Technical Report also gives recommendations for the further development of European Standards for the determination of the bio-based content.
