NBN ISO 16620-2:2021

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 14
C 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.
