At CIRAM, we perform ASTM D6866 compliant carbon 14 analyses to accurately determine the proportion of bio-based carbon in industrial products.

The ASTM D6866 standard was launched in 2004. It defines the testing methods that allow to determine the content of bio-based carbon of solid, liquid, and gaseous materials using radiocarbon analysis.
It is based on the distinction between:
The analytical methods used (AMS, IRMS, or LSC, as appropriate) allow this proportion to be quantified with an uncertainty generally ranging from 0.1% to ±3%, depending on the protocols and laboratories. In addition, the method uses international reference materials to ensure the traceability of measurements and their comparability across laboratories.
For an in-depth analysis, you can consult our dedicated article: In which cases should ASTM D6866 be used?
Explore the areas of applicationMany companies from the sectors of biomaterials,biofuels or renewable energies call on CIRAM to analyze the bio-based content of their products according to standard ASTM D6866.
Within this regulatory framework, CIRAM implements the ASTM D6866 standard in a rigorous analytical setting: the analyses carried out by our laboratory are based on accelerator mass spectrometry (AMS), the reference technology for measuring carbon 14.
This technique makes it possible to accurately quantify the proportion of carbon from modern sources as opposed to fossil carbon, based on the natural presence (or absence) of carbon-14 in the materials.
Our results are expressed in percentage of bio-based carbon, with a controlled uncertainty of 0.3 to 0.5%, making them directly usable in your technical documents, certification files, or commercial arguments.
Request a quoteBy choosing CIRAM, you are relying on an independent scientific laboratory, specializing in radiocarbon dating and analysis for over 20 years. Our laboratory is recognized for its mastery of ASTM D6866 methods, and offers you:
All products containing at least 1% carbon: liquids, solids, or gases. Even formulated and complex products are eligible.
Yes. It is often used as a supplement to or equivalent of European standards and is widely accepted, and even recommended, in requests for proposals and environmental audits.
Carbon-14 analysis provides independent scientific proof, uninfluenced by supplier declarations or technical data sheets.
Yes, CIRAM results can be integrated into ecolabel, LCA, biosourced certification or CSR reporting dossiers.
Of course. We'll show you how to collect, package and securely ship your samples.
The currently applicable version is the standard ASTM D6866-24a, published in 2024.
