Plastics - Determination of bio-based carbon content

This Technical Specification specifies a calculation method for the determination of the bio-based carbon content in monomers, polymers and plastic materials and 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: Proportional scintillation-counter method (PSM);
-   Method B: Beta-ionisation (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 polymers containing organic carbon, including biocomposites.
NOTE   This Technical Specification does not provide the methodology for the calculation of the biomass content of a sample.

Kunststoffe - Bestimmung des biobasierten Kohlenstoffgehalts

In dieser Technischen Spezifikation wird das Berechnungsverfahren festgelegt, nach dem der Gehalt an
biobasiertem Kohlenstoff in Monomeren, Polymeren, Kunststoffen und Produkten unter Anwendung des
14C-Verfahrens bestimmt wird.
Es werden auch drei Prüfverfahren zur Bestimmung des 14C-Gehalts beschrieben, aus dem der biobasierte
Kohlenstoffgehalt zu errechnen ist:
⎯ Verfahren A: Proportional-Szintillationszähler-Verfahren (PSM);
⎯ Verfahren B: Beta-Ionisation (BI);
⎯ Verfahren C: Beschleuniger-Massenspektrometrie (AMS).
Der biobasierte Kohlenstoffgehalt wird als Anteil der Probenmasse bezogen auf den Anteil des
Gesamtkohlenstoffgehalts oder bezogen auf den Anteil des gesamten organisch gebundenen Kohlenstoffgehalts
Dieses Berechnungsverfahren ist auf alle Polymere anwendbar, die organischen Kohlenstoff enthalten und
auch auf Bioverbundwerkstoffe (Biocomposita).
ANMERKUNG In dieser Technischen Spezifikation wird kein Verfahren für die Berechnung des Biomasseanteils einer
Probe angegeben.

Plastiques - Détermination de la teneur en carbone biosourcé

La présente Spécification technique spécifie une méthode de calcul basée sur le mesurage du 14C, qui permet
de déterminer la teneur en carbone biosourcé des monomères, polymères, matières plastiques et produits en
Elle spécifie également trois méthodes d'essai à utiliser pour déterminer la teneur en 14C à partir de laquelle la
teneur en carbone biosourcé sera calculée :
- Méthode A : méthode au compteur de scintillation proportionnel (PSM) ;
- Méthode B : ionisation Bêta (BI) ;
- Méthode C : spectrométrie de masse par accélérateur (AMS).
La teneur en carbone biosourcé est exprimée en fraction de masse d'échantillon, comme une fraction de la
teneur en carbone total ou une fraction de la teneur en carbone organique total.
Cette méthode de calcul est applicable à tout polymère contenant du carbone organique, biocomposites
NOTE La présente Spécification technique n'indique pas la méthodologie pour calculer le contenu en biomasse d'un

Polimerni materiali - Določevanje ogljika biološkega izvora

Ta tehnična specifikacija določa računsko metodo za določevanje ogljika biološkega izvora v monomerih, polimerih, polimernih materialih in proizvodih na osnovi merjenja vsebnosti 14C.
Določa tudi tri preskusne metode, ki se uporabljajo za določevanje vsebnosti 14C, iz katere se izračuna ogljik biološkega izvora:
- metoda A: proporcionalna metoda s scintilacijskim števcem (PSM);
- metoda B: beta-ionizacija (BI);
- metoda C: pospeševalna masna spektrometrija (AMS).
Ogljik biološkega izvora se izrazi z deležem mase vzorca kot delež skupnega ogljika ali kot delež skupnega organskega ogljika.
Ta metoda izračuna velja za vse polimerne materiale, ki vsebujejo organski ogljik, vključno z biokompoziti.
OPOMBA: Ta tehnična specifikacija ne podaja metodologije za izračun biomase vzorca.

This Technical Specification (CEN/TS) was approved by CEN on 20 December 2010 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, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
