ISO 16620-2-2019 塑料--生物基成分--第2部分:生物碳成分的测定 Plastics — Biobased content — Part 2: Determination of biobased carbon content

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.nd edition 2019-10 Plastics — Biobased content — Part 2: Determination of biobased carbon content Plastiques — Teneur biosourcée — Partie 2: Détermination de la teneur en carbone biosourcé Reference number ISO 16620-2:2019(E) ？ ISO 2019 ISO 16620-2:2019(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2019 All rights reserved.
