From local standards to the EN14961
The quality requirements for pellets were adhered to, in Germany in the DIN 51731, in Austria
in the ÖNORM M 7135 and in Switzerland in the standard SN 166000.
With the certificate "DIN-Plus
", the DIN 51731 and ÖNORM M7135 were unified and supple-
mented by requirements for abrasion resistance and testing procedure.
The "EN14961" replaces the respective national regulations: The corresponding "ENplus" certifi-
cate simplifies the difficulty consumers have when selecting but it also regulates the professio-
nal handling of the pellets by the trade: Gentle transport, optimal filling of the pellet storage
container ...
The pellets for your KWB heating system must comply with one of the following standards:
•
ÖNORM M 7135 or DIN 51731 (standardised quality requirements) or
• "ENplus"certificate according to standard EN 14961-2 (www.enplus-pellets.de)
• SN 166000
Inferior fuels lead to increased emissions and to sintering of the boiler. Only high-quality pellets
ensure a reliable and clean operation of your system and low operating costs. Observe the cor-
responding certificate of your supply company.
