Determination of bio-based materials in bio-based content Liquid scintillation counter method1 ScopeThis standard specifies the use of a liquid scintillation counter measuring bio-based materials in bio-based content of instruments and reagents, test procedures and results of calculations. This standard applies to bio-based materials such as bio-based plastics, and organic carbon in these materials can be oxidized to carbon dioxide gas.2 Normative referencesThe following documents for the application of this document is essential.

ISO 8245.1999 Quality of total organic carbon (TOC) and dissolved organic carbon (DOC) Guidelines for the determination [Waterquality- Guidelinesforthedeterminationoftotalorganiccarbon (TOC) anddissolvedorganiccarbon (DOC)]3 Terms and DefinitionsThe following terms and definitions apply to this document. 3.1 Bio-based materials biobasedmaterial The use of biomass as a feedstock in the manufacture of new materials and chemicals, including bio-based plastics, bio-based chemicals, sugar, engineering products, and Renewable biological resources such as grains, legumes, cotton and straw and wood cellulose and other biomass as a raw material or plastic composite materials. 3.2 Fossil carbon fossilcarbon Substantially free of radioactive carbon-carbon, which is much larger than the half-life of 14C ages (5730 years). 3.3 Modern carbon moderncarbon Modern carbon. 1959 International Conference confirmed the US National Bureau of Standards developed by oxalic acid (SRM4990b) as the standard modern carbon Quality, and its 1950 95% of the radioactivity of carbon as a modern standard radioactivity. 3.4 Biobased Content biobasedcontent Organic carbon per gram of sample radioactivity and modern carbon per gram of organic carbon in the reference material radioactivity ratio percentage. Meaning it represents Si sample is the percentage of renewable resources of modern organic carbon total organic carbon, rather than a percentage of the total mass of the sample. 3.5 The efficiency of counting efficiency The number of observations or measurements to count the results of the measurement period and the occurrence of decay activity rates, expressed as a percentage. Principle 4 Upon the death of a living organism, it will stop the intake of new carbon. All organisms died twelve carbon isotope (12C) and Radiocarbon apposition ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 29649-2013_English be delivered?Answer: Upon your order, we will start to translate GB/T 29649-2013_English as soon as possible, and keep you informed of the progress.
