The purpose of this European Standard is to provide a method for determining the bio-based content of solid, liquid and gaseous products using radiocarbon and elemental analysis. This European Standard applies to all solid, liquid and gaseous products containing the element carbon, provided that a declaration is available listing the composition and origin of the product. This method is not needed for the determination of the bio-based content in natural products wholly derived from biomass. The responsible national standardization committee is Working Committee NA 172-00-11 AA "Biobasierte Produkte" ("Bio-based products") at DIN Standards Committee Principles of Environmental Protection.
