BS EN Standards

Fuel standards and classes

The general fuel specifications and classes for all solid biofuels are set out in BS EN 14961-1:2010, which defines certain parameters and property classes.  On top of this are BS EN 14961 parts 2 to 5 which cover the fuel specifications and classess for specific types of solid biofuels for non-industrial usage, such as wood pellets, chips, firewood, etc.

Some of the key standards that apply to solid biofuels are listed below.
