Accredited Test Centre for Wood Firing Systems FHNW
The testing centre for wood-burning stoves is accredited as a type C laboratory by the Swiss Accreditation Service SAS. A type C laboratory is authorised to develop and validate its own test procedures and have these procedures accredited and can therefore respond much more flexibly to the specific needs of customers.
The test centre is accredited for the testing of
- Room heaters according to EN 16510-2-1
- Heating inserts according to EN 16510-2-2
- Cookers according to EN 16510-2-3
- Residential boilers according to EN 16510-2-4
- Pellet room heaters according to EN 16510-2-5
- Storage heaters according to EN 15250
- Boilers for solid fuels according to EN 303-5
- Boilers for solid fuels up to 1 MW according to own procedure
- Safety testing for boilers up to 10 MW according to our own procedure
Outside of accreditation, measurements and interpretation of the measured values can be carried out on all types of furnaces according to customer requirements.
