标准摘要
[中文适用范围]： 本文件规定了基于 14C 含量测量测定单体、聚合物以及塑料材料和制品中生物基碳含量的计算方法。 本文件适用于由生物基或化石基成分制成的塑料产品和塑料材料（例如增塑剂或改性剂）、聚合物树脂、单体或添加剂。 了解塑料产品的生物基含量在评估其环境影响时非常有用。 [外文原描述]： This document specifies a calculation method for the determination of the biobased carbon content in monomers, polymers, and plastic materials and products, based on the 14C content measurement. This document is applicable to plastic products and plastic materials (e.g. plasticisers or modifiers), polymer resins, monomers, or additives, which are made from biobased or fossil-based constituents. Knowing the biobased content of plastic products is useful when evaluating their environmental impact.
