scope:

This European Standard specifies a method for the determination of the loss on ignition (LOI) of dry mass at 550 °C. The dry matter has been determined in accordance with the method of 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 non-volatile 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.
