DIN EN 15403:2011-05

This standard specifies a method for the determination of ash content of 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 organizations. 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.
The European Standard has been prepared by Technical Committee CEN/TC 343 "Solid recovered fuels", the secretariat of which is held by SFS (Finland). The responsible German committee is Working Committee NA 062-05-83 AA "Sekundärbrennstoffe" ("Recovered fuels") of NMP.
