Bio-based products - Determination of the bio based carbon content of products using the radiocarbon method

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 is calculated:
-   Method A: Liquid scintillation-counter method (LSC);
-   Method B: Beta-ionization (BI);
-   Method C: Accelerator mass spectrometry (AMS).
The bio-based carbon content is expressed by a fraction of sample mass, as a fraction of the total carbon content or as a fraction of the total organic carbon content.
This calculation method is applicable to any product containing organic carbon, including biocomposites.
NOTE   This Technical Specification does not provide the methodology for the calculation of the biomass content of a sample.

Biobasierte Produkte - Bestimmung des biobasierten Kohlenstoffanteils von Produkten mittels Radiocarbonmethode

Diese Technische Spezifikation legt ein Verfahren zur Bestimmung des Gehalts an biobasiertem Kohlenstoff in Produkten auf der Grundlage der Messung des 14C-Gehalts fest.
Es werden auch drei Prüfverfahren festgelegt, die zur Bestimmung des 14C-Gehalts anzuwenden sind, aus dem der biobasierte Kohlenstoffgehalt berechnet wird:
 Verfahren A: Flüssigszintillationszählverfahren (LSC);
 Verfahren B: Beta-Ionisation (BI);
 Verfahren C: Beschleuniger-Massenspektrometrie (AMS).
Der biobasierte Kohlenstoffgehalt wird als Anteil der Masse der Probe angegeben, als Anteil des gesamten Gehalts an Kohlenstoff oder als Anteil des Gehaltes an organischem Kohlenstoff.
Dieses Berechnungsverfahren ist auf alle Produkte anwendbar, die organischen Kohlenstoff enthalten, einschließlich Bioverbundwerkstoffen.
ANMERKUNG Diese Technische Spezifikation bietet kein Verfahren für die Berechnung des Biomassegehalts einer Probe.

Produits biosourcés - Détermination de la teneur en carbone biosourcé des produits par la méthode du carbone radioactif

La présente Spécification technique spécifie une méthode permettant de déterminer la teneur en carbone biosourcé dans des produits à partir du mesurage de la teneur en 14C.
Elle spécifie également trois méthodes d'essai à utiliser pour déterminer la teneur en 14C, à partir de laquelle la teneur en carbone biosourcé est calculée :
-   Méthode A : compteur à scintillation liquide (CSL) ;
-   Méthode B : ionisation bêta (IB) ;
-   Méthode C : spectrométrie de masse par accélérateur (SMA).
La teneur en carbone biosourcé est exprimée en fraction de masse d'échantillon, en fraction de la teneur en carbone total ou en fraction de la teneur en carbone organique total.
Cette méthode de calcul est applicable à tout produit contenant du carbone organique, y compris les biocomposites.
NOTE   La présente Spécification technique ne fournit pas la méthodologie permettant de calculer la teneur en biomasse d'un échantillon.

Bioizdelki - Ugotavljanje deleža bioogljika v izdelkih z radioogljično metodo

Standard CEN/TS 16640 določa metodo za ugotavljanje deleža bioogljika v izdelkih na podlagi meritve deleža 14C. Prav tako določa tri preskusne metode za ugotavljanje deleža 14C, na podlagi katere se izračuna delež bioogljika: – metoda A: metoda števca s tekočinskim scintilatorjem (LSC); – metoda B: beta ionizacija (BI); – metoda C: pospeševalna masna spektrometrija (AMS). Delež bioogljika se izrazi z deležem mase vzorca kot delež skupnega deleža ogljika ali kot delež skupnega deleža organskega ogljika. Ta metoda izračuna se uporablja za vse izdelke, ki vsebujejo organski ogljik, vključno z biokompoziti.

This Technical Specification (CEN/TS) was approved by CEN on 9 December 2013 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United
Kingdom.
