DIN EN 14961-6:2012-04

This European Standard determines the fuel quality classes and specifications of non-woody pellets for nonindustrial use. This European Standard covers only non-woody pellets produced from the following raw material: herbaceous biomass; fruit biomass; biomass blends and mixtures. Blends are intentionally mixed biofuels, whereas mixtures are unintentionally mixed biofuels. The objective of this European Standard is to provide unambiguous and clear classification principles for solid biofuels and to serve as a tool to enable efficient trading of biofuels and to enable good understanding between seller and buyer as well as a tool for communication with equipment manufacturers. This standard will also facilitate authority permission procedures and reporting. This European Standard is made to support the use of non-woody pellets in non-industrial situations and specifically for the domestic/householder markets and smaller commercial boiler situations, where sensitivity to the fuel quality can cause major issues. Non-woody pellets have high ash, chlorine, nitrogen and sulphur content and major element contents, so non-woody pellets are recommended to be used in appliances, which are specially designed or adjusted for this kind of pellet. The committee responsible for this document is NA 062-05-82 AA "Feste Biobrennstoffe" ("Solid biofuels") at DIN.
