本欧洲标准规定了基于14C含量测量法测定产品中生物基碳含量的方法。 本欧洲标准还规定了用于测定生物基碳含量的14C含量的三种测试方法: 方法A:液体闪烁计数法（LSC）（规范）; - 方法B:β-电离（BI）（资料性）; - 方法C:加速器质谱（AMS）（规范性）。 生物基碳含量由样品质量的一部分或总碳含量的分数表示。该计算方法适用于任何含有碳的产品，包括生物复合材料。 注意本欧洲标准没有提供计算样品生物量的方法，参见prEN 16785-1 [5]和prEN 16785-2 [6]

This European Standard specifies a method for the determination of the bio-based carbon content in products, based on the 14C content measurement. This European Standard also specifies three test methods to be used for the determination of the 14C content from which the bio-based carbon content is calculated: - Method A: Liquid scintillation-counter method (LSC) (normative); - Method B: Beta-ionization (BI) (informative); - Method C: Accelerator mass spectrometry (AMS) (normative). The bio-based carbon content is expressed by a fraction of sample mass or as a fraction of the total carbon content. This calculation method is applicable to any product containing carbon, including bio composites. NOTE This European standard does not provide the methodology for the calculation of the biomass content of a sample see prEN 16785-1 [5] and prEN 16785-2 [6].
