Woodfuel Standards

There have been several woodfuel standards used in the UK biomass industry for the provision of wood fuel, these being:

  • Önorm – An ÖNORM standard is a national standard published by the Austrian Standards Institute.
  • EN Standards – European Standards (ENs) are documents that have been ratified by one of the three European Standardization Organizations
  • ISO Standards – The International Organization for Standardization (ISO) is an international standard-setting body composed of representatives from various national standards organizations

British Standards (BS) are the standards produced by the BSI Group which is incorporated under a royal charter and which is formally designated as the national standards body (NSB) for the UK.
