The approval of the new EU standard for wood pellets (EN
14961-2) was at mid 2010 and introduces new certificates
ENplus for pellets, utilized in domestic heating appliances,
the certificate EN-B is applied for industrial boilers. The
standard ENplus defines classes of the wood pellets, which
could be considered as qualifications:
А 1 and А 2. The class
А 1 introduces the most stringent limits for the ash content in
the wood pellets. The class А 2 defines ash content up to 1.5%. For industrial
applications the wood pellets should cover the requirements of the certificate
EN-B, which is less stringent, that the previous and the generally the quality of
the pellets is lower.
