ASTM D6866 biobased carbon testing

Radiocarbon measurement of biobased carbon as a fraction of total organic carbon by accelerator mass spectrometry — a physical test of what a sample contains, independent of any accounting attribution.

Where it's used

Bio-content certification and mass-balance traceability (ISCC PLUS, USDA BioPreferred)
How a bio-based claim is made provable — ISCC PLUS chain-of-custody certification over mass-balanced production, radiocarbon measurement of biogenic carbon under ASTM D6866, and the digital product passport regime the EU adopted in July 2026 to carry such claims through the supply chain.
