WARNING — Persons using this European Standard should be familiar with usual laboratory practice. This European Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. IMPORTANT — It is absolutely essential that tests conducted according to this European Standard be carried out by suitably trained staff. Special measures shall be taken during the ignition process to prevent contamination of the laboratory atmosphere by flammable, explosive or toxic gases. SIST EN 15935:2012

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
