Bio-based products - Bio-based content - Part 1: Determination of the bio-based content using the radiocarbon analysis and elemental analysis

This European Standard specifies a method of determining the bio-based content in products, based on the radiocarbon analysis and elemental analysis. This European Standard is applicable to any solid, liquid and gaseous product containing carbon element, provided that a statement giving the composition and the origin of the product is available. This method is not needed for the determination of the bio based content in natural products wholly derived from biomass.
