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

This European Standard specifies a method for the determination of the bio-based carbon content in products, based on the 14C content measurement.
This European Standard 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) (normative);
-   Method B: Beta-ionization (BI) (informative);
-   Method C: Accelerator mass spectrometry (AMS) (normative).
The bio-based carbon content is expressed by a fraction of sample mass or as a fraction of the total carbon content. This calculation method is applicable to any product containing carbon, including bio composites.
NOTE   This European standard does not provide the methodology for the calculation of the biomass content of a sample see prEN 16785-1 [5] and prEN 16785-2 [6].

Biobasierte Produkte - Gehalt an biobasiertem Kohlenstoff - Bestimmung des Gehalts an biobasiertem Kohlenstoff mittels Radiokarbonmethode

Diese Europäische Norm 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) (normativ);
-   Verfahren B: Beta Ionisation (BI) (informativ);
-   Verfahren C: Beschleuniger Massenspektrometrie (AMS) (normativ).
Der biobasierte Kohlenstoffgehalt wird als Anteil der Masse der Probe angegeben oder als Anteil des gesamten Kohlenstoffgehalts. Dieses Berechnungsverfahren ist auf alle kohlenstoffhaltigen Produkte anwendbar, einschließlich Bioverbundwerkstoffen.
ANMERKUNG   Diese Europäische Norm bietet kein Verfahren für die Berechnung des Biomassegehalts einer Probe; diesbezüglich siehe prEN 16785 1 [5] und prEN 16785 2 [6].

Produits biosourcés - Teneur en carbone biosourcé - Détermination de la teneur en carbone biosourcé par la méthode au radiocarbone

La présente Norme européenne 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) (normative) ;
-   Méthode B : ionisation bêta (IB) (informative) ;
-   Méthode C : spectrométrie de masse par accélérateur (SMA) (normative).
La teneur en carbone biosourcé est exprimée en fraction de masse d'échantillon ou en fraction de la teneur en carbone total. Cette méthode de calcul est applicable à tout produit contenant du carbone, y compris les biocomposites.
NOTE   La présente Norme européenne ne fournit pas la méthodologie permettant de calculer la teneur en biomasse d'un échantillon ; voir le prEN 16785-1 [5] et le prEN 16785-2 [6].

Bioizdelki - Delež bioogljika - Ugotavljanje deleža bioogljika z radioogljično metodo

Ta evropski standard določa metodo za ugotavljanje deleža bioogljika v izdelkih na podlagi meritve deleža 14C.
Poleg tega ta evropski standard določa tri preskusne metode za ugotavljanje deleža 14C, na podlagi katerih se izračuna delež bioogljika:
– Metoda A: metoda števca s tekočinskim scintilatorjem (LSC) (normativni);
– Metoda B: beta ionizacija (BI) (informativni);
– Metoda C: pospeševalna masna spektrometrija (AMS) (normativni).
Delež bioogljika se izrazi z deležem mase vzorca ali kot delež skupnega deleža ogljika. Ta metoda izračuna se uporablja za vse izdelke, ki vsebujejo ogljik, vključno z biokompoziti.
OPOMBA: ta evropski standard ne zagotavlja metodologije za izračun deleža biomase vzorca. Glej standard prEN 16785-1 [5] in prEN 16785-2 [6].
