At this moment,i will share ASTM D6866-18,Standard Test Methods for Determining the Biobased Content of Solid, Liquid, and Gaseous Samples Using Radiocarbon Analysis.
ASTM D6866-18 has been SUPERSEDED by ASTM D6866-20.
This standard is a test method that teaches how to experimentally measure biobased carbon content of solids, liquids, and gaseous samples using radiocarbon analysis.
The definitions of terms used in these test methods are referenced in order that the practitioner may require further information regarding the practice of the art of isotope analysis and to facilitate performance of these test methods.
Terminology D883 should be referenced for terminalogy relating to plastics. Although an attempt to list terms in aogical manner (alphabetically) will be made as some terms require definition of other terms to make sense.
The specific safety and regulatory requirements associated with radioactivity, sample preparation, and instrument operation are not addressed in these test methods. It is the responsibility of the user of these test methods to establish appropriate safety and health practices.
