Technical Specification [Withdrawn]

DIN CEN/TS 16640 ; DIN SPEC 35800:2014-05
Bio-based products - Determination of the bio-based carbon content of products using the radiocarbon method; German version CEN/TS 16640:2014

Title (German)

Biobasierte Produkte - Bestimmung des biobasierten Kohlenstoffanteils von Produkten mittels Radiocarbonmethode; Deutsche Fassung CEN/TS 16640:2014

Procedure

Overview

This Technical Specification specifies a method for the determination of the bio-based carbon content in products, based on the ¹⁴C content measurement. It also specifies three test methods to be used for the determination of the ¹⁴C content from which the bio-based carbon content can be calculated: - Method A: Liquid scintillation-counter method (LSC); - Method B: Beta-ionization (BI); - Method C: Accelerator mass spectrometry (AMS).This calculation method is applicable to any product containing organic carbon, including bio-composites. The Working Committee responsible for this Technical Specification is NA 172-00-11 AA "Biobasierte Produkte" ("Bio-based products") at DIN Standards Committee Principles of Environmental Protection (NAGUS).
