FAQ | ASTM D6866 Bio Testing

ASTM D6866 is a standard specifically developed for biobased content measurements. The U.S. Department of Agriculture requested the development of this method because it needed a precise and reliable tool for verifying the biobased content claims under its BioPreferred Program. Many biobased manufacturers use the ASTM D6866 method to also verify their feedstocks, which are often derived from biofuels. No other method that can determine the biocarbon fraction has this level of accuracy and precision.

Yes, ASTM D6866 can be used for biobased content testing of biofuels. Regulators do accept ASTM D6866 results. Some regulations recommend or require ASTM D6866.

Not all radiocarbon dating labs have the technical expertise or the manpower to provide a quick turnaround time. Commercial radiocarbon dating labs that are ISO/IEC 17025:2005-accredited are recommended because the U.S. Department of Agriculture and other organizations strongly encourage the use of laboratories that have such accreditation.

For liquid fuels, 100-200 microliters of a combustible liquid is sufficient (3 mL max). For CO2 emissions, 1 liter is sufficient if the gas is not diluted. Send 5 liters for diluted CO2 samples.

Liquid samples should be placed in tightly sealed vials that are wrapped properly to prevent breakage during shipment. Vials with snap caps, like those shown below, can be used. You can also use vials found at this site.

We have an office in London, UK, but hazardous samples need to be shipped under the guidelines of “Dangerous Goods in Excepted Quantities” to the US lab because other BETA offices are not equipped to handle biofuels. Please send to:
