Towards international pellet standards

摘要

The International Organisation for Standardisation (ISO) is currently preparing almost 60 standards for solid biofuels which will supersede EN standards in Europe following the application of Vienna agreement1 (see Figure 1). Due to be published in March 2014 as ISO EN standards, values for these standards have been agreed and include: ISO 17225-1 (general requirements), ISO 17225-2 (graded pellets) and ISO 17225-6 (non-woody graded pellets).
