Sludge, treated biowaste, soil and waste - Determination of loss on ignition

This European Standard specifies a method for the determination of the loss on ignition (LOI) of dry matter at 550 °C. The dry matter is determined according to EN 15934.
This method applies to the determination of loss on ignition of sludge, treated biowaste, soil and waste. The LOI of sediments can also be determined with this method.
NOTE   The loss on ignition is often used as an estimate for the content of organic matter in the sample. It should be noted that inorganic substances or decomposition products (e.g. H2O, CO2, SO2, O2) are released or absorbed and some inorganic substances are volatile under the reaction conditions.

Schlamm, behandelter Bioabfall, Boden und Abfall - Bestimmung des Glühverlusts

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Glühverlusts der Trockenmasse bei 550 °C
fest. Die Trockenmasse wurde mit dem Verfahren nach EN 15934 bestimmt.
Dieses Verfahren zur Bestimmung des Glühverlusts ist anwendbar für Schlamm, behandelten Bioabfall,
Boden und Abfall. Der Glühverlust von Sedimenten kann ebenfalls mit diesem Verfahren ermittelt werden.
ANMERKUNG Der Glühverlust dient oft als Schätzwert für den Gehalt an nicht flüchtigen, organischen Bestandteilen in
der Probe. Anorganische Stoffe oder Zersetzungsprodukte (z. B. H2O, CO2, SO2, O2) werden freigesetzt oder
aufgenommen und einige anorganische Stoffe sind unter den Reaktionsbedingungen flüchtig.

Boues, bio-déchets traités, sols et déchets - Détermination de la perte au feu

La présente Norme européenne spécifie une méthode de détermination de la perte au feu (LOI) de la matière sèche à 550 °C. La teneur en matière sèche est déterminée conformément à l'EN 15934.
Cette méthode s'applique à la détermination de la perte au feu des boues, des bio-déchets traités, des sols et des déchets. La perte au feu des sédiments peut également être déterminée par cette méthode.
NOTE   La perte au feu est souvent utilisée comme une estimation de la teneur en matière organique dans l'échantillon. Il convient de noter que des substances inorganiques ou des produits de décomposition (par exemple, H2O, CO2, SO2, O2) sont libérés ou absorbés et que certaines substances inorganiques sont considérées comme étant des matières volatiles dans les conditions opératoires.

Blato, obdelani biološki odpadki, tla in odpadki - Določevanje žarilne izgube

Ta evropski standard določa metodo za določitev žarilne izgube suhe snovi pri temperaturi 550 °C. Suha snov je opredeljena v skladu s standardom EN 15934. Ta metoda velja za določitev žarilne izgube za blato, predelane biološke odpadke, prst in odpadke. S to metodo se lahko določi tudi žarilna izguba za usedline.

3.2 residue on ignition mass fraction remaining after burning up a dried sample to constant mass at a specified temperature 4 Principle A weighed test portion is burned up in a furnace to constant mass at (550 ± 25) °C. The difference in mass before and after the ignition process is used to calculate the loss on ignition. The determination is performed on a dried sample or directly on the undried sample including a drying step or by referring to the dry matter. 5 Interferences and sources of errors LOI is an empirical parameter, thus in principle there is no interference connected to the determination. However, for some purposes the determination of LOI is used for the assessment of the content of organic matter in the sample. It should be noted that elementary carbon in the sample will be included in the loss on ignition value. Furthermore, any volatilisation or chemical reactions of inorganic compounds will also be included in the loss on ignition value. Chemically bound water could be released during heating, thereby contributing to the loss on ignition. SIST EN 15935:2012
