DIN EN 15440:2011-05

This document specifies three normative methods for the determination of the biomass fraction in solid recovered fuel, and when to use each method. The methods are the selective dissolution in a hydrogen peroxide/sulphuric acid mixture, the manual sorting method and the method based on the 14C content. The determination of the biomass content using the 14C method is based on the well established analytical procedures that are used for the determination of the age of carbon containing objects. The method of selective dissolution is based on the reaction of biomass material with a mixture of sulphuric acid and hydrogen peroxide. The manual sorting method is based on the separation of different fractions on visual aspects.
