标准范围

本文件规定了一种基于放射性碳分析和元素分析测定塑料产品中生物基质量含量的方法。本文件适用于由生物基和/或化石基成分制成的塑料产品和塑料材料、聚合物树脂、单体或添加剂。只要塑料产品含有元素碳并且给出其元素组成和其生物基碳含量的声明是可用的，就可以应用该方法。

This document specifies a method of determining the biobased mass content in plastics products, based on the radiocarbon analysis and elemental analysis.

This document is applicable to plastic products and plastic materials, polymer resins, monomers or additives, which are made from biobased and/or fossil-based constituents.

This method can be applied provided that the plastic product contains the element carbon and that a statement giving its elemental composition and its biobased carbon content is available.
