NOTE: Beta Analytic is not affiliated with ISO or its technical committees. However, you are welcome to contact BETA ANALYTIC on how to submit samples for ISO 16620 biobased content testing.
In April 2015, the International Organization for Standardization (ISO) published a series of standards focused on the biobased content of plastics. Two of the standards, ISO 16620-2:2015 and ISO 16620-3:2015, can determine the exact percentage of carbon in the plastic material that comes from renewable sources or biomass.
ISO 16620-2 includes Carbon-14 analysis and expresses biobased carbon content as a fraction of sample mass, total carbon content, or total organic carbon content.
The published standards are:
ISO 16620-1:2015 Plastics — Biobased content — Part 1: General principles
ISO 16620-2:2015 Plastics — Biobased content — Part 2: Determination of biobased carbon content
ISO 16620-3:2015 Plastics — Biobased content — Part 3: Determination of biobased synthetic polymer content
There are two more standards in the series that are currently in various stages of development:
ISO/DIS 16620-4 Plastics — Biobased content — Part 4: Determination of the biobased mass content
ISO/CD 16620-5 Plastics — Biobased content — Part 5: Declaration of biobased carbon content, biobased synthetic polymer content and biobased mass content
These ISO standards are applicable to plastic products, polymer resins, monomers, or additives, which are made from biobased or fossil-based constituents. Developed by ISO Technical Committee ISO/TC 61 Sub-committee 5, the standards are available for download at the ISO website for a fee.
ISO/IEC 17025:2005-accredited Beta Analytic provides biobased content testing as described under ISO 16620-2. The lab uses accelerator mass spectrometry (AMS) to determine the biobased carbon content of plastic products. Beta Analytic routinely reports results in 3-5 business days with online reporting, technical consultation, and quality assurance reports included. Customer service is available in English, Chinese, French, German, Italian, Japanese, Korean, Portuguese, Spanish, and Turkish.
