Plastics — Biobased content — Part 4: Determination of biobased mass content

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.

Plastiques — Teneur biosourcée — Partie 4: Détermination de la teneur en masse biosourcée

L'ISO 16620-4:2016 spécifie une méthode de détermination de la teneur en masse biosourcée dans les produits plastiques, basée sur l'analyse au radiocarbone et l'analyse élémentaire. L'ISO 16620-4:2016 s'applique aux produits plastiques et aux matériaux plastiques, aux résines polymères, aux monomères ou aux additifs qui sont fabriqués à partir de constituants biosourcés ou d'origine fossile. La présente méthode s'applique à condition que le produit plastique contienne l'élément carbone et qu'une déclaration indiquant sa composition élémentaire et sa teneur en masse biosourcée soit disponible.
