BS EN 15935:2021 PDF

Scope: What is BS EN 15935 about? In soil science, the loss on ignition test is conducted to analyze the minerals and chemical makeup of the soil. After strongly heating the sample, you determine the mass of what is left. BS EN 15935 specifies a method for the determination of the loss on ignition (LOI) at 550 °C. The dry matter is determined according to EN 15934 . BS EN 15935 applies to the determination of loss on ignition of sediment, sludge, treated biowaste, soil and waste. Note: The loss on ignition is often used as an estimate for the content of organic matter in the sample. 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.
