The International Organization for Standardization (ISO) standards for solid biomass fuels will be available for purchase in the next week in the ISO store.
The international standards agency outlined the need for standards for solid biofuels, including wood pellets, chips and other densified biomass, in an article published on its website, “Stoking the biofuel flame.”
Eija Alakangas, ISO project leader for the ISO 17225 series, pointed out that while there are existing standards in Europe and the U.S., “several test methods have been used. If you trade your solid biofuels internationally, you have to complete a number of tests to prove the quality of your fuels and, as things stand today, you cannot compare results because they have been derived using different methods.”
Part 1: General Requirements of the ISO 17225 series gives an overview of the standards, which include “the fuel quality classes and specifications for solid biofuels of raw and processed materials originating from a) forestry and arboriculture; b) agriculture and horticulture; and c) aquaculture.” Part 2: Graded wood pellets, outlines quality classes and specifications of graded wood pellets for nonindustrial and industrial use.
