ISO 16620 discusses the biobased content of plastics. ISO 16620-2 is the second part of the ISO 16620 multi-series and discusses the determination of biobased carbon content in plastics.
ISO 16620-2 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.
ISO 16620-2 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.
ISO 16620-2 on biobased carbon content in plastics is useful for:
Increased use of biomass resources for manufacturing plastic products is effective in reducing global warming and the depletion of fossil resources. Current plastic products are composed of biobased synthetic polymers, fossil-based synthetic polymers, natural polymers, and additives that can include biobased materials.
“Biobased plastics” refer to plastics that contain materials, wholly or partly of biogenic origin. The “biobased content” of biobased plastics refers to the amount of the biobased carbon content, the amount of the biobased synthetic polymer content, or the amount of the biobased mass content only.
ISO 16620-2 provides you with terminology definitions and symbols on biobased carbon content and guides you with the sampling. ISO 16620-2 helps you to determine the 14C content and the total carbon content and total organic carbon content. ISO 16620-2 guides you with the calculation of the bio-based carbon content and test report. ISO 16620-2 helps you to find the biobased carbon content in monomers, polymers, and plastic materials and products.
BS ISO 16620-2:2019 supersedes BS ISO 16620‑2:2015, which is withdrawn. BS ISO 16620-2:2019 includes a technical change with respect to BS ISO 16620‑2:2015. That is:
