Not all laboratories providing ASTM D6866 biobased content testing are qualified to provide such service to applicants of the U.S. Department of Agriculture’s BioPreferred® Program. Biobased content testing labs must first be accepted by the USDA. The labs must be ISO 17025-accredited, have no direct exposure to artificial carbon-14 and can demonstrate capability to perform ASTM D6866 testing.
The ISO/IEC 17025 standard specifies the general requirements for laboratories to demonstrate competence, impartiality and consistency in carrying out tests, calibrations and sampling. According to the International Organization for Standardization (ISO), the ISO 17025 standard allows laboratories to implement a sound quality system and demonstrate that they are technically competent and able to produce valid and reliable results.
Results of labs that are ISO 17025-accredited are accepted by many laboratories worldwide. Test reports and certificates of ISO 17025-accredited labs can be accepted from one country to another without the need for further testing, thereby improving international trade.
Under the standard’s scope and limitations, it is explicitly stated that ASTM D6866 is applicable only to laboratories working without exposure to artificial carbon-14.
According to ASTM International, artificial carbon-14 can become undetectably ubiquitous on lab surfaces and may randomly contaminate an unknown sample producing inaccurately high biobased content results.
Labs are required to disclose several details to assess their competence in ASTM D6866 testing, including:
The USDA BioPreferred Program is an initiative of the US government to increase consumption of biobased products and create jobs. As of June 2022, the Program has identified 139 product categories.
Certified-only products – they do not fit into one of the categories qualified for mandatory federal purchasing but have gone through the BioPreferred Program’s certification process; Qualified-only – biobased products that fall under one of the product categories but have not gone through the program’s certification process; Qualified/Certified – biobased products that belong in one of the product categories AND have gone through the program’s certification process.
Based in Miami, Florida, Beta Analytic has performed ASTM D6866 testing since 2004. The lab joined the American Society for Testing Materials (ASTM) Subcommittee D20.96 in 2004 to help author the ASTM D6866 standard.
An ISO 17025-accredited lab since 2008, tracer-free Beta Analytic does not accept biomedical samples or any materials with artificial carbon-14, carbon-13, carbon-12 or any other isotopes to avoid the risk of cross-contamination.
For inquiries on rates and lab turnaround time, please call 305-662-7760 or use this contact form.
Beta Analytic is not affiliated with ASTM or the USDA BioPreferred Program. The lab welcomes inquiries on how to submit samples for testing as part of the Biopreferred Voluntary Labeling Program.
