This part of EN 16785 specifies a method of determining the bio-based content in products, based on the radiocarbon analysis and elemental analysis.

As a direct analytical determination is not feasible, this method consists in requiring from the producer or his representative some data given in a statement, and comparing these data with the results of the radiocarbon and elemental analysis.

This European Standard is applicable to any solid, liquid and gaseous product containing carbon, provided that a statement is available about the elemental composition and the bio-based content of the product(s).

This method is not needed for the determination of the bio-based content in natural products wholly derived from biomass.
