DIN EN 15403:2011-05

This document specifies a method for the determination of ash content of all solid recovered fuels. It is primarily geared toward laboratories, producers, suppliers and purchasers of solid recovered fuels but is also useful for the authorities and inspection organisations. The sample is heated in air atmosphere up to a temperature of (550 +- 10) °C under rigidly controlled conditions of time, sample mass and equipment specifications. The ash content is determined by calculation from the mass of the residue remaining after heating.
