Sludge, treated biowaste, soil and waste - Determination of total organic carbon (TOC) by dry combustion

This European Standard specifies two methods for the determination of total organic carbon (TOC) in sludge, treated biowaste, soil, waste and sediment samples containing more than 1 g carbon per kg of dry matter (0,1 %).
When present, elementary carbon, carbides, cyanides, cyanates, isocyanates, isothiocyanates and thio-cyanates are determined as organic carbon using the methods described in this European Standard. An interpretation of the measured value may therefore be problematic in cases where the samples contain relevant levels of the above mentioned components. If necessary, these components should be determined separately by means of a suitable validated procedure and be recorded in the test report.
For sludge, treated biowaste and soil only Method A is validated.

Schlamm, behandelter Bioabfall, Boden und Abfall - Bestimmung des gesamten organischen Kohlenstoffs (TOC) mittels trockener Verbrennung

Diese Europäische Norm legt zwei Verfahren zur Bestimmung des gesamten organischen Kohlenstoffs (TOC) in Schlamm, behandeltem Bioabfall, Boden, Abfall und Sedimentproben fest, die mehr als 1 g Kohlenstoff je Kilogramm Trockenmasse (0,1 %) enthalten.
Für Schlamm, behandelten Bioabfall und Boden ist nur das Verfahren A validiert.

Boues, bio-déchets traités, sols et déchets - Détermination de la teneur en carbone organique total (COT) par combustion sèche

La présente Norme européenne spécifie deux méthodes de détermination de la teneur en carbone organique total (COT) dans des échantillons de boues, de bio-déchets traités, de sols et de sédiments contenant plus de 1 g de carbone par kg de matière sèche (0,1 %).
Pour les boues, les bio-déchets traités et les sols, seule la méthode A est validée.

Blato, obdelani biološki odpadki, tla in odpadki - Določevanje celotnega organskega ogljika (TOC) s suhim sežigom

Ta evropski standard določa dve metodi za določitev skupnega organskega ogljika (TOC) v blatu, predelanih bioloških odpadkih, prsti, odpadkih in vzorcih usedlin, ki vsebujejo več kot 1 g ogljika na kg suhe snovi (0,1 %). Za blato, predelane biološke odpadke in prst je potrjena samo metoda A.

3.2 total inorganic carbon TIC quantity of carbon that is liberated as carbon dioxide by acid treatment 3.3 total organic carbon TOC quantity of carbon that is converted into carbon dioxide by combustion and which is not liberated as carbon dioxide by acid treatment 4 Principle 4.1 Method A (indirect procedure) In this procedure, the TOC is obtained by the difference between the results of the measurements of TC and TIC. The total carbon (TC) present in the sample is converted to carbon dioxide by combustion in an oxygen-containing gas flow free of carbon dioxide. To ensure complete combustion, catalysts and/or modifiers can be used. The released amount of carbon dioxide is measured by infrared spectrometry, thermal conductivity detection, flame ionisation detection after reduction to methane, or by gravimetry, coulometry, conductometry after absorption.
