Technical Note SB28: International wood pellet standard ISO 17225

The International Organisation for Standardisation (ISO) has prepared almost 60 standards for solid biofuels. In Europe these standards supersede EN-standards, in particular EN14961-2.

Under ISO 17225-series there are standards for pellets: ISO 17225-1 (general requirements for all kind of pellets), ISO 17225-2 (graded pellets for household and commercial applications and for industrial use) and ISO 17225-6 (non-woody graded pellets for household and commercial applications).

Commercial applications means facilities that utilise solid biofuel burning appliances or equipment that have the similar fuel requirements as residential appliances.
