During 2016 and 2017 the European standards for solid fuel boilers and roomheaters have been under revision. RISE has taken active part in this work as a representative for Swedish interests. This includes meetings in the Swedish mirror committee SIS TK 169, participation in CEN Technical Committees TC 57 and 295 and in relevant working groups as well as continuous dissemination work. The report describes issues addressed at the meetings, Swedish positions and arguments as well as the status of the revision process.
