The approval of the new European standard for pellets (EN 14961-2) has introduced new certificates: ENplus
for pellets used in devices for domestic heating; EN-B for industrial boilers. The standard defines the ENplus
wood pellet classes in A1 and A2. The A1 class introduces more severe limits on the possible ash residue. The
A2 class allows for a ash residue content up to 1.5%.

1) no more than 1% of the pellet may be longer than 40 mm. Maximum length allowed: 45mm
2) Determined on the dry measurement
3) < 3.15 mm particles (fine dust particles before fuel dispensing)
4) for measurements carried out with a Lignotester, the limit value of the base weight in% is ≥ 97.7
